Do-it-yourself centrifugal water filter. We clean the water with our own hands: a homemade filter

There is a well-established opinion among the people that the purest and most useful water is brought from a well. However, modern life has made its own adjustments even to this seemingly unshakable rule. Today, the water contained in wells is not at all as pure as we imagine it to be. Therefore, people who are forced to use it often need to make a water filter with their own hands.

Why filter water?

Unfortunately, well and borehole water contains a number of impurities that can adversely affect the health of people who consume it. These are all kinds of chemical elements contained in modern fertilizers, and microbes that penetrate into groundwater during the construction of cesspools and septic tanks.

On the other hand, rust on metal parts also leads to deposits and bad taste. That's why filtering well water is absolutely necessary.

What can be used to purify water?

Perhaps everyone knows the principle of the filter: water just needs to be passed through the filter material. As it is possible to use:

• cotton wool;
• piece of cloth;
• Paper;
• Cleaning systems made from natural ingredients (sand, coal)
• The most common, perhaps, are gauze filters.

Unfortunately, most of these materials, for all their effectiveness, have one serious drawback. They are short lived.

This is a variant of the simplest and most affordable water filter from improvised materials.

You can, of course, purchase an industrial-made filter jug, but there is also a negative point in using it. You will have to regularly update the filter cartridges.

Types of homemade filters

There are several ways to make a homemade well water filter. They differ in the labor required to make them and in the amount of water available for cleaning.

Plastic bottle filter system

The simplest filter can be made using the most common plastic bottle. The method of its manufacture is elementary.

1. We take a plastic bottle and cut off the bottom of it.
2. We use a bucket with a plastic lid. It needs to cut a hole of the appropriate size.
3. Now we install the bottle in the slot with the narrow part down.
4. Pour the filter material into the bottle.

The best filler for filters for a small cottage is charcoal.

At the same time, it is also possible to make coal with your own hands. For this purpose, pieces of wood (with the exception of conifers) are calcined in metal containers. You can, of course, buy ready-made coal, sold in bags.

Advice! To ensure a good fit of the parts of the resulting structure, go over the edge of the hole cut in the lid with sandpaper. In addition, it is desirable to use a rubber gasket.

The same method is used in the manufacture of a somewhat more complex installation. This will be the same simple filter for giving, but larger. For this:

• We take a twenty-liter container.
• A hole is made in the bottom of this container and a crane is installed.
• And you will also need a ten-liter plastic bottle, in which you need to make a hole in the bottom.
• To make a carbon filter, you can use a cut pipe made of polypropylene. We glue perforated plastic to it from above and below. Then coal is poured into the pipe.
• The resulting simple filter is installed in the neck of the bottle.
• After that, you can connect all parts of the device.

Such a home-made water filter is convenient in that up to 10 liters of well water can be poured into it at once, thereby providing a decent supply.

Advice! Before the first use, be sure to clean the system by passing a sufficient amount of water through it, which is better then poured out. This method will remove the suspension, which can contaminate the liquid.

Three-flask installation

In the event that the house is equipped with running water, it is often necessary to make a homemade water filter. After all, tap water is also usually quite far from ideal purity.

In this case, it would be nice to make a three-flask design yourself.

You will need 3 identical flasks, which are connected using 2 adapters. They should be ¼ inch. The thread during installation must be sealed using FUM tape.

The resulting system is mounted in the water supply using a tee. To do this, you need a half-inch connector. Then a regular faucet is connected. The flasks are filled with the material to be used for filtration.

Such a simple homemade filter will quite effectively purify tap water.

Bottom filter

A more radical solution would be to clean well well water using a bottom filter. Such a system is laid even at the stage of digging a well or when cleaning it.

Deciding to resort to such filtering, you must first evaluate the quality of the bottom of the well.

• If the bottom consists of soft clay, then it can be strengthened with coarse gravel. The layer should be from 15 to 20 cm.
• A bottom filter is installed on the sandy bottom to help get rid of sand suspended in the water.
• In the presence of sand - floating water, the bottom filter is complemented by a wooden shield.
• The clay bottom does not need additional reinforcement.

The filter is installed in the following way.

• First, if necessary, a wooden shield made of hardwood is installed. Then you need to put the filter material itself. Depending on the material of the bottom, it fits in different ways.
• Straight. It is used when the bottom consists of soft clay or if a shield is already installed. In this case, the filter material is laid according to the principle “from a larger fraction to a smaller one”. It is necessary to lay at least three layers: large stones, small pebbles, sand. The thickness of each layer is at least 15 cm.
• Back. At the bottom of the well, consisting of sand, the layers are laid in the reverse order. This method does not allow grains of sand to rise.

This filter must be cleaned annually.

Whether you decide to install the simplest water filter in your home or country house or prefer a more complex home-made design, in any case, it is quite possible to do all the work yourself. Most importantly, as a result, the issue of water purification will be resolved for a sufficiently long time and will allow you not to worry about the health of all family members.

Since its inception, mankind has been looking for any possibility of water purification. From the Middle Ages to the age of modern technology and innovation. After all, at the moment of its existence, life on earth, environmental problems are becoming more and more.

Due to the constant development of technological processes, emissions of harmful chemical compounds into the atmosphere or soil are growing every year. After these harmful substances penetrate into groundwater.

In our article you will learn:

Filter characteristic

Recently, the filter for purifying running water in the form of a jug is gaining popularity. This filter has the simplest device and can be built from household scrap materials. This filter is suitable if you need to purify a couple of liters of water.

If we talk about large volumes, then you have to try, but the principle of the device of these filters is identical.

A properly made such filter is able to purify water without problems, but it is better not to use it immediately after filtering, but to let it stand for a while.

Modeling stage

Installing a filter for purifying running water will not be difficult enough. You will need a container where filtered water will drain, glass is best. Next, you can take any plastic bottle and cut it to the middle.

Thus, we form a container, the so-called jug. Then we start the device directly to the filter itself. To do this, we need filter wool and graphene sorbent.

A layer of filter wool is placed on the bottom of the funnel of a cut bottle, then a sorbent is placed and closed with a layer of filter wool. Thus, we get the simplest filter for water purification.

What is a graphene sorbent?!

So graphene sorbent is primarily a chemical element, carbon, whose structure has been radically changed. Graphene carbon is a kind of modification that allows the passage of water molecules, various salts and allows you to keep impurities, which include chemical elements, oil products.

In order for the graphene sorbent to perform its intended functions, it must be compacted to form a membrane.

Rainwater Treatment Methods

There are many ways to purify rainwater. It depends primarily on the number of downpipes, namely where to arrange the filter - on the roof or on the ground.

If the number of drainpipes is not small, then a kind of coarse filter should be arranged at the bottom of the drainpipe in order to initially clean the water from leaves, stones, droppings. The coarse filter, which is located in the downpipe, is constructed from a stainless steel mesh.

But in this article we will give an example of a do-it-yourself rainwater filter, without complex technological solutions.

Preparation and installation

First you need to purchase barrels, for example, plastic or wooden ones. The barrel should be arranged directly under the downpipe. It should be at a short distance from the building and it is recommended to place either bricks or stones under it.

Next, we cut in the tap, which we will later use to drain the filtered water. We install a solid partition in the barrel and make small holes, then covering them with a water-permeable membrane. Next, let's get to the fun part!

Filter modeling stage

At this stage, we will understand in detail how to make a filter for rainwater purification.

To begin with, we pour a small layer of pebbles, about 10-15 cm thick, onto the bottom canvas. After that, on top of the pebble layer, we lay a layer of river sand of approximately the same thickness. Next, lay a small layer of gravel. It is advisable to arrange a layer of gravel and river sand together as a whole.

The next layer, namely the last one, is a layer of granulated coal. An analogue of granular charcoal is hard maple charcoal.

The next stage is tamping - we create a very dense and rather thick membrane, which is the filter. All filter elements must be covered with the top sheet. The canvas can be changed according to the degree of contamination, and the filter itself is recommended to be replaced every season, as it, like all materials, wears out.

Such a filter can be created for containers of any size, the main thing is to follow the technological process and the correct filter design.

I hope this article will be useful and informative for you!

DIY water filters photo

You have an urgent need to filter the liquid, then you can make a filter for water purification with your own hands. Most often, drinking water filtration is needed in the field, one of the simple options is presented in the video. It is also not uncommon for cases when you need to make a home-made filter unit for purifying water from the water supply system.

Why you need to purify water

Water from open sources is characterized by the following physical and chemical parameters:

1. Taste - sour, salty, sweet, bitter. It comes from dissolved impurities and gases.
2. The smell is hydrogen sulfide, marsh, putrefactive, fishy, ​​silty, etc. Its source is substances found in wastewater or naturally released into the liquid.
3. Turbidity and color - come from organic constituents, particles of clay and silt, microorganisms.

To make the simplest homemade filter, you can use the Aquaphor cartridge. The price of such a filter is about 400 rubles, for this cost you can filter about 200 liters of water.

In addition, water that has not passed at least a simple water filter contains industrial and domestic effluents, combustion products of various types of fuel, harmful chemical elements, particles of dolomites, lime, gypsum, and sand.

The Aquaphor filter is great for hiking and traveling. With this filter you can filter river or rain water. To be safe, boil water before drinking.

All this can cause:

• diseases of the gastrointestinal tract;
• intoxication of the body;
• the accumulation of salts in it, which lead to diseases of the joints, bladder, the formation of stones in the gall and kidneys, allergic reactions, the development of iron bacteria.

In these cases, water purification even with homemade filters dramatically reduces the likelihood of negative consequences for humans.

How to choose a filter media

This water filtration is the most elementary, and as we know: “Everything ingenious is simple!”

To weed out solid particles suspended in liquids, salts, excess iron, and also adsorb odors, different materials are used as filter element fillers:

1. Cotton wool, linen fabric, cotton will do to assemble a fabric filter for water purification.
2. You can make a charcoal version of the device for cleaning - use a product that is produced for cooking barbecue.
3. For short-lived appliances take paper napkins. They well eliminate suspensions that are not able to dissolve.
4. A high-quality sorbent is a natural mineral of volcanic origin - zeolite. It absorbs odors, mold, toxins.
5. After washing and disinfection in the oven or on fire, gravel, quartz sand or stones of medium and fine fractions are used to filter the water.
6. Mechanical cleaning can be organized using lutrasil, a non-woven fabric made of polypropylene, which is common in agriculture.
7. At the molecular level, silver has a disinfecting effect. You can use any suitable items made of this metal.

Activated carbon device for dirty water treatment

Coal will help remove pollution of organic and inorganic origin, as well as ozonize and eliminate water chlorination products.

As a filler in a homemade carbon-based filter, a product washed with alkalis or acids (activated) or regenerated is used.

If you purchase coal with a silver coating, you will get a product with bactericidal properties. Without such treatment, microorganisms and bacteria are able to penetrate the filter device.

Used coal can be restored 3-4 times as follows:

• rinse with running water 2-3 times, placing it in an enamel bowl;
• 2-3 hours to let stand;
• dissolve soda (3% bicarbonate) in 3 liters of water and pour the regenerated product with the composition;
• boil the mixture for half an hour;
• strain after draining and rinsing.

In the manufacture of a cleaning system, you need to consider:

• water pressure;
• liquid temperature (do not filter boiling water);
• the absence of nearby sources of heating, which can lead to the loss of sorbent properties.

Activated carbon is characterized by a porous structure, due to which purification occurs. For this, both powder material and granular material are suitable.

The quality of the resulting water depends on the thickness of the layer. The rate of passage of the liquid through the filter is selected so as to provide the time required for the contact of the liquid with coal for cleaning. 100g of product can reliably neutralize 200ml of water in 1 minute.

Small-sized varieties of marching type

A small filter for water purification from toxic substances and mineral formations, which you can take with you when going out into nature, hunting or fishing, is easy to make. The product will remove the consequences of the vital activity of microorganisms, rid the liquid of an unpleasant odor and taste, and make the drink transparent.

It is important to choose the right structure of the mineral. A good level of cleaning in a portable device will provide medium-sized granules - large ones will let dirt through, and small powder particles will seep into the liquid.

Make a hole in a cigar case and fill it with filter elements. We fill the case like this: at the very bottom two cm of cotton, then a layer of ground activated carbon eight cm, after a layer of cotton 2 cm. All layers are clamped with a plate of permeable porous plastic, which is used in industrial water filters.

For homemade devices, it is better to take charcoal from birch and other hardwood trees. The needles can give the water a specific smell. It is easy to prepare the material yourself. It is required to glow red-hot in an oven or on fire in a metal bowl pieces of wood and cool.

If the need for filtration arose unexpectedly, then the remaining coals and ash from the fire will be suitable as a filler. The combustion products are loaded into a plastic bottle or any other suitable container and liquid is passed through them.

Making a carbon water purifier

A carbon water filter can be assembled in a more suitable housing.

For this you need to prepare:

1. Cartridge, the basis of which is made from several food containers or plastic bottles.
2. A suitable tool is a screwdriver or an awl, a knife, scissors.
3. The filler is charcoal, cooked by yourself or bought in advance.
4. Granulates that can further improve the quality of drinking liquids are gravel, quartz sand.
5. Plugs or covers made of plastic.
6. Gauze, bandage or cloth to make the initial rough cleaning of large debris.

The joints of the device are strengthened with electrical tape or silicone glue. For ease of use, a home-made device can be hung by threading a cord or wire through holes made in a plastic bottle with a cut off bottom. A lid is suitable as a tap, which can be unscrewed a few turns so that water flows.

To facilitate the subsequent replacement of the filler, a fabric cover is often used. Then the filter layers are laid. Gravel, pebbles are placed last. First, coal and sand. At the neck, you can lay cotton wool as a fine filter.

The main disadvantage of such systems is the slow filtration process.

Useful homemade PVC pipe

Homemade water filters that can compete with industrial products can be made for a country house or cottage. If water is supplied from a lake, pond, river, a well is drilled or a shaft well is made, the installation of filtering devices is necessary.

Cleaning devices are made using improvised means. Will need:

• 2 containers;
• part of a plastic water pipe - 50-80 cm;
• caps from plastic bottles;
• cotton wool;
• filler;
• instruments.

The procedure for the manufacture of a water filter from PVC pipe.

1. A lid is glued into a PVC pipe, in which several holes are made. It will act as a mesh substrate when laying cotton wool and gauze as the primary layers of the filter.
2. A layer of synthetic winterizer is placed and another cover is laid without glue.
3. The neck, cut off from the bottle, is attached to the pipe with the thread outward. Wrap with tape.
4. At the other end, a cover with a fabric gasket is fixed.
5. The tube is filled with activated carbon.
6. The segments are connected with a thread and plastic bottles are placed on both sides.

Aquarium water filter

A flow device to purify water in aquariums is made independently at home.

The body can be constructed from 2 syringes or take a plastic tube of the desired diameter. To fix the device to the wall, you need a suction cup. Instrument assembly:

1. Remove the moving part from the syringes and remove. Cut off the noses of the remaining parts and connect the tubes with hot glue to each other.
2. Use a soldering iron or a heated nail to make holes on the surface of one of the syringes.
3. Place the zeolite and the atomizer inside the product.

Sand option for the pool

Before you make a water filter with your own hands, you need to decide on the volume of liquid that you want to clean. If the displacement is small, then home-made devices with sand filling are suitable.

The functions of the cartridge can be performed by any container of a suitable size. Fluid inlet and outlet pipes are brought into it and sand or other filler is laid. To turn the pipe, a PVC corner is useful.

For effective cleaning, several containers can be connected together using an M10 threaded sleeve. A compressor is connected to the system, the power of which is calculated depending on the volume of the pool.

Homemade water filter

The water filter is independently made from 3 containers in series. It will only function under pressure.

A 1/4" adapter nipple is suitable for connecting glass or plastic containers together. When assembling, follow the guides indicated on the parts.

Seal the joints of the product with synthetics. For threading, you can use Teflon tape.

The filter elements are connected to the water supply system in series through a tee. Activated carbon is used as a filler.

Conclusions and useful video on the topic

Homemade water filters are a good way to protect the human body from harmful minerals, as well as from debris and scale - household appliances - washing machines and kettles.

In most cases, making a device at home is cheaper than buying a factory one. To fill the device, improvised materials are used.

Charcoal, gauze, or a coffee filter can be used to improve water quality, and it’s not difficult to make them yourself.

Filters help get rid of the following substances and manifestations:

• chlorine impurities;
• nitrates;
• sulfates;
• nitrites;
• pesticides;
• odors;
• coloration;
• turbidity;

Unfortunately, this method of purification is also not ideal, it has features and limitations in use.

Self-manufacturing

Filter device

Features of the manufacture of simple filters– in multi-layered materials with different cleaning properties. Each new level contributes to the additional removal of impurities, contaminants or certain properties of water.

To build a filter with your own hands, you can use available fillers and simple fixtures.

At home, for a homemade filter as cleaners, you will need:

1. Paper napkins, gauze or a wide bandage. Water from a well or water supply is perfectly cleaned with their help, but the fragility of materials is the reason for their frequent replacement.
2. Thin cotton, canvas, or linen fabric, cotton wool is more durable in composition, they last longer.
3. , which can be purchased at the store or made independently.
4. silver coin or other small silver items.
5. small pebbles, gravel, clean river or quartz sand, previously washed and calcined for disinfection.

As containers for unfiltered and purified water, you can use a plastic or enameled bucket with a lid and a plastic five-liter bottle. The volume of dishes used can be increased or decreased depending on the need.

Walkthrough:

1. Step 1. In the lid of a bucket for clean water, in the center you need to cut a hole for screwing a plastic bottle upside down. The fit of the two elements must be tight. The cut edges should be processed with sandpaper or a file, and 5-6 punctures should be made in the bottle cap to drain the purified liquid.
2. Step 2 Preparing a container for water purification. If a five-liter or other plastic bottle is used, then you need to carefully cut off the bottom to fill the vessel with filter materials and insert it into the hole in the bucket lid.
3. Step 3 In the place of the neck, a thin fabric or cotton wool is laid in layers from the inside with a snug fit to the walls. From above, you need to fill in pre-prepared crushed coal 5-6 cm high and compact it a little with a heavy object. This is the main filtering component, its capabilities are calculated approximately from the ratio: 1 tablet of activated carbon per 1 liter of liquid.
4. Step 4 On top of a layer of coal, you need to spread gauze or a bandage in several layers, carefully closing the previous level, and place silver pieces or coins on top for bacterial cleaning.
5. Step 5 Place a layer of clean sand 2-2.5 cm high and make sure that it does not leak to the coals. Mixing can cause the filter to clog. Sand enhances filtration without letting in foreign particles. From above it is necessary to lay gauze in 4-5 layers so that there is no funnel when filling the container with water.
6. Step 6 You can start test cleaning after filling the container. If the design is determined for a continuous supply of water, then it is important to monitor the pressure, which should not exceed the throughput of the filter.

The performance and quality of filter cleaning depend on the number of layers and their density. It is considered the best indicator for cleaning 2-3 liters of water per hour.

It should be noted that purchased filters essentially have the same cleaning properties, even if pyrolyzed ground coconut shells are used instead of carbon filler.

You can prepare charcoal yourself by calcining a hardwood tree placed in a metal dish in a fire. Ephedra cannot be used due to the large amount of resins they contain. Birch logs are ideal for making activated carbon.

The filtration layers should fill approximately 2/3 of the total volume of the bottle, and 1/3 remains for unfiltered water.

DIY flow filter

Manufacturingpossible, provided that the water is supplied with a certain and stable pressure. The main purpose of such installations is the removal of chlorine odors, additional cleaning and disinfection.

To assemble the design, you will need three flasks of the same size, filler and ¼ inch nipple adapters with carrier direction markings. The filter material may be carbon.

The flasks must be connected in series, the middle one must be filled with filter material. The filter is connected to the water supply system with a tee. Connections are carefully sealed to prevent leakage.

It should be remembered that over time the filters themselves become dirty too. Cloth, cotton and paper cleaners should be changed as they wear out. Sand can be washed with reverse water flow until the water is completely transparent.

The carbon layer must be replaced due to infection with bacteria. The maximum filtration period for sand is 3 months and for coal is 1 month.

Overview of Filtration Materials

Water purification is carried out through porous layers of materials that can be replaced as needed or in connection with the tasks. To determine the quality level of filtration, water must be sent for laboratory analysis. Sometimes it is enough to taste and visually feel the difference between the original and purified water.

The main list of filtration materials is traditional: cotton wool, gauze, cotton fabrics, pebbles, coal. But sometimes the question arises, what to prefer and why?

River or quartz sand

For the purpose of mechanical purification of water from impurities and contaminants, sand is used. Quartz is considered the most suitable due to the suitable shape of its grains and mineral purity. The angularity of the particles resists sticking, this property is important for filtration. Quartz sand is finely dispersed, which enhances the quality of water purification.

Charcoal or coconut shell charcoal

The use of coal is associated with the purification of pesticides, traces of chlorine, ozone, organics due to the adsorption process. Efficiency is achieved under the condition of the porosity of the structure.

If the coal was manufactured in a factory way, then the technologies ensure the presence of pores in charcoal. Independent production of coal does not lead to the desired stage, although there will still be a certain porosity.

The best cleansing structure of charcoal is achieved by charring coconut shells or pits of plums, apricots or peaches.

An additional component for a filter that has recently appeared on the modern market. The presence in it of special fibers made of polypropylene provides high-quality cleaning from impurities and substances harmful to humans.

Principle of operation

How a reverse osmosis system works

Water passes through several layers of the filter, successively freed from various contaminants. The more levels, the higher the degree of purification. Fillers can be different, each has its own filtration features and capabilities.

First stage cleaning- this is a mechanical screening through porous materials of particles of rust, sand, clay, any debris that may be contained in the water. In this way, transparency is achieved, giving an external appearance of purity.

Subsequent filters can change the color, taste, smell of water, change its chemical composition.

In the role of cleaning layers are used:

• fabrics or gauze;
• cotton wool;
• paper napkins;
• quartz sand;
• charcoal;
• lutraxil;

To conduct effective water filtration, you need to know its features, composition. This information helps in filter selection. For example, when receiving water from an artesian well, a lot of iron and hardness salts get into the drilling process. Accordingly, cleaning should be aimed at removing iron content with a selected reagent.

Advantages and disadvantages

Cleaning structures made independently from improvised means and materials are quite inexpensive, convenient and affordable. This is their great advantage over purchased filters, installations that do not take root in country houses, dachas at all because of the cost and unacceptable conditions for use.

Any inhabitant can make the simplest and at the same time effective filter using household tools and appliances: a knife, a plastic bottle, a bucket, cloth and other materials.

The disadvantages of homemade designs for traditional filtration are:

1. Failure to trap contaminants and high-level infection. The pores of the filters can only partially resist harmful substances.
2. A typical purifier problem is the internal accumulation of contaminating microorganisms., the concentration of which increases with the use of filtration materials. The lack of self-cleaning affects the operation of the entire system as a whole. But no solution to this problem has yet been found.
3. Microelements necessary for a person in particles, commensurate with the size of pollution, are also retained by filters and demineralize water.

The problem of drinking water purification is becoming relevant not only for citizens, but also for rural residents. To make water from a well or well drinkable, you can make a water filter with your own hands.

Why filter well water?

It would seem that what could be cleaner than well water, sung in ancient Russian epics? Alas, modern reality is not at all like a fairy tale. Water in private wells can be contaminated with a variety of substances, such as:

• nitrates;
• bacteria and pathogens;
• impurities that impair the taste and quality of drinking water.

For an excess of nitrates in drinking water, i.e., salts of nitric acid, one should “thank” the farmers who widely use fertilizers and pesticides in the cultivation of agricultural products. Some of these substances inevitably seep into the aquifer of the soil.

Bacteria and other dangerous microorganisms appear in wells and wells, since sanitary and hygienic standards in the construction of cesspools and manure pits, toilets and other similar structures are often not observed as strictly as they should.

The simplest filter can be made from a plastic bottle with filler

Poor quality and damage to equipment lead to the fact that an admixture of rust, sand, etc. appears in the water. Drinking such water is simply unpleasant. Therefore, for giving it is recommended to buy or make at least a simple water filter.

Overview of filtration materials

The principle of operation of the filter is simple and familiar to everyone. It is necessary to pass water through a layer of filter material. The filler may be different:

• the cloth;
• cotton wool;
• paper napkins;
• gauze;
• sand;
• grass;
• coal;
• lutraxil.

Filters made of gauze, cotton wool, paper napkins, cloth and other similar materials are quite effective, but short-lived. They need to be changed quite often. However, as a temporary option, they are quite suitable.

You can buy charcoal at the store or make your own.

For regular use, other materials are used, mainly charcoal. It is laid in layers, alternating with sand, gravel, grass, etc. Lutraxil is a synthetic material made from polypropylene fibers.

Tip: You can make your own charcoal. To do this, it is enough to ignite pieces of wood in a metal container. Coniferous wood is not suitable for this. Ready-made charcoal is sold in stores, in the picnic departments.

The simplest plastic bottle filter

The use of conventional household filters for a small cottage is rarely convenient. Such devices require water to flow from the water supply under a certain pressure, and not every country house has a water supply with suitable characteristics. Pitcher filters purify water too slowly.

In addition, you will have to constantly change cartridges. Therefore, a homemade water filter made from a plastic bottle and a bucket with a plastic lid may be the most viable option.

Homemade water filter can be made from an ordinary plastic bottle

This filter uses charcoal and ordinary cloth as a filler.

The simplest filter for giving is made in this way:
1. Cut off the bottom of a plastic bottle.
2. Cut a suitable hole in the plastic lid of the bucket.
3. Insert the bottle into the hole with the neck down.
4. Fill the filter with media.

Tip: It is important to ensure that the bottle is firmly attached to the edges of the hole made in the bucket lid. To do this, process the edges of the hole with sandpaper, and also use a rubber gasket.

By the same principle, you can make a more convenient filtration unit. A plastic canister or tank of about 20 liters is used as a receiving container. At the bottom you need to make a hole and insert a small faucet into it, through which purified water will flow.

On top of the receiving container, you need to install a plastic bottle with a volume of 10 liters, in the bottom of which a filling hole has been made. For the manufacture of the filter, you can use a piece of 40 mm polypropylene pipe. The top and bottom of the pipe are covered with pieces of perforated plastic, which is recommended to be fixed with hot glue. The pipe is filled with charcoal.

Such a homemade filter should fit tightly into the neck of a standard ten-liter bottle. It remains to connect the receiving tank with the filter and the bottle. A full bucket of well water can be immediately poured into the installation, which will be filtered after a few hours. Thus, the house will always have a supply of clean drinking water.

Please note: The charcoal filter must be washed before use. To do this, several liters of water are passed through it, which is immediately drained. As a result, small particles of coal that can pollute the water will be removed.

Three-flask design for a full plumbing

Happy owners of a full-fledged water supply in a private house can make a three-flask home-made filter for water purification. For this you need:

1. Buy three identical flasks.
2. Connect the flasks in series with two quarter-inch nipples. In this case, it is necessary to strictly adhere to the in / out designations in order to observe the direction of water movement. The threads of the nipples should be sealed with FUM tape.
3. The end holes of the flasks are connected to the quarter-inch tube with straight adapters.
4. Connect the filtration system to the water supply with a tee that is cut into the water supply using a 1/2” connector.
5. At the outlet, a standard tap for drinking water is connected to the filter system.
6. Fill the flasks with filter material. You can use a polypropylene cartridge, a carbon filter and an anti-scale filler.

Filter cartridges are very diverse and allow you to eliminate a wide variety of water contaminants. It is worth noting that the cost of such a do-it-yourself design may not be much lower than an inexpensive filtration unit from the manufacturer.
