How to make a water filter

Man can not live long without water.On the day only one person on the planet have an average of 2-2.5 liters of water.To stay in shape and feel good, you must be sure to keep drinking regime.Water consumption must meet the sanitary standards and have to be clean.Residents of big cities need to take care about the quality of the water suitable for drinking.There are several options: to buy a stationary water filter or set up your own mini-cleaning station.Not everyone turns to resolve this question in the affirmative, so a great alternative - a water filter to make your own.

in a city or in the countryside is always a risk that the water will not be suitable for use in raw form.Even if it is clean, then By doing a long way, it passes through dirty pipes, tanks and so on.If the water storage tanks will get germs and bacteria, it is very difficult to get rid of them.

If you remember, back in the S

oviet times, special services were notified tenants of the houses on the water filtration.In those days it was impossible to use tap water, because it had a bad smell of chlorine.Drinking such water was impossible, except for a long time to maintain and boil.At such times, to carry out disinfection of tanks, used bleach.It kills germs, but could not cope with the main task - water purification from impurities.Then it was invented home purifiers for water, which served as the basis for the creation of the first industrial filters.

to always get out of the tap, borehole or well clean water and drink it without fear, you can make your own water filter.

What is a filter?

Filter - a special device that allows you to clear the water from the large and small impurities.coarse filter cartridges do not cope at 100% with its task, as the fine grains remain in the water.To purify water quality, you should use the modern filter.It purifies the water from the fine particles of salts of heavy metals, chlorine, bacteria and pathogens.As a result, the proper treatment, even the usual raw water from the tap becomes harmless to humans.

What you need to filter the water from the well?This question is raised by many villagers.After all, before nobody thought about to pass water from the well by special devices.It was enough to collect a bucket of well water and use as directed.Now the situation has changed, and not always well water can be consumed without fear, because it is possible to "find" a lot of harmful substances.This heavy salt, bacteria, microorganisms, nitrate, nitric acid (irrigation and field processing), other pesticides and fertilizers.Some of these substances in growing agricultural products, remain in the ground and seep into aquifers.

If you examine the issue thoroughly, it becomes clear that the pit, manure pit, and toilets often do not meet safety standards, so the pathogens into the water, too.Drink this water is not only frustrating, but also very dangerous!Therefore, to prevent the spread of serious diseases, it is necessary to install a water filter.On the market there are many different models, which differ in performance and operating principles.The cost of the device ranges from 200 rubles (filter-pitcher) to 40 thousand rubles (individual filter station).

If you can not buy a filter in the store, we offer a great option - to make a water filter with your hands.

Materials for water filters

principle of operation of any of the filter device is the same - it is necessary that the water has passed through the filter material.This may be an ordinary fabric, or gauze, folded in several layers, wadding, dense paper napkins, and grass, sand or coal.

for temporary water purification suitable gauze, cloth, cotton or paper towels.They are perfectly clean water, but it will last for long, as they will have to be changed frequently.If you want to build a temporary filter for the purification of water, then you can use these materials.

more reliable and durable filter media - is charcoal.It is available on their own or buy a few bags in the store.The principle of construction of a home filter is simple: you need to put a layer of clean coal wood (preferably without impurities), a layer of sand, grass or gravel, then again a layer of coal and so on.As an upper layer can use a special material - "Lutrasil", which is made of propylene fibers.

If you want to save the filter charcoal is easy to make yourself.To do this, take the wooden logs (pure, not stained with paint, varnish or stain), and ignited in a metal tray.Remember that coniferous wood is not suitable for filter structures, as they have a lot of essential oils.

How to filter the water with their hands

If we compare the classic low-cost filter in the form of the tank, but it is possible to find out that the capacity of such devices is small, only a few liters - filter may be used only 1 person, and the family of the2 or more people this is not an option.There is another disadvantage when using - receiving tank located above the second vessel, and is inserted into the filter through which water infiltrates into the reservoir therebetween.We have to wait a long time until the water purification will take place and it can be used for other purposes.Will take into account these defects in the manufacture of a water filter.

to filter structures we need:

  • canister of food grade plastic with a capacity of 20 liters;
  • collapsible valve for water;
  • hot melt adhesive;
  • plastic bottle to 10 liters;
  • washer and threaded rod;
  • section of plastic pipe with a diameter of 40 mm;
  • charcoal;
  • filter for tie-in plumbing.

How to make a water filter:

  1. For receptacle we use plastic canister.It is necessary to insert into the bottom of the canister collapsible crane.It can not buy, and unscrew with tetrapaketa of wine.This crane is very convenient for the construction of the filter, if you click on it - the liquid flows, release - valve closes.
  2. At the bottom of the cans need to cut a small hole to insert the valve.Put him best for hot melt.The initial capacity
  3. serve liter bottle 10 from the drinking water.
  4. should be cut with a sharp knife in the tank filler opening.
  5. neck of the cans and bottles capacity should match the diameter, so an additional fix nothing.Neck "sits" in the hole very tight.
  6. as the filter element, we take the finished filter, which is used to tie into the existing water supply systems.It is mounted to the inside of the cans, because the element through the neck passes.To filter
  7. tight "sat" in the container, it is necessary to press by means of washers (in the lower part a drain hole) and studs.
  8. Putting together all components and test a homemade filter.It is possible to do otherwise, and instead of the finished filter cartridge to make their own charcoal.To do this you will need a piece of a pipe, in which you need to put charcoal to connect the pipe to the neck and secure with a homemade filter with hot melt glue.As a gasket, the bottom of the napkin or can assume a folded in several layers of fabric or gauze.
  9. to coal remained inside the pipe, the back end also need to close the cloth and reliably fix.
  10. Now insert the filter into the neck of the bottle and put it on top of the canister.Get more filter.
  11. Testing our homemade cartridge.Pour into the tank 5 liters of water, it is enough to "pump" the carbon filter.Look, what will be the water, it will flow muddy, with fine coal particles - this is normal.The next time the water is clear.

Performance of the handmade filter about 3 liters per hour.If you fill the filter with a homemade evening, in the morning, you can enjoy clean water.It is very convenient as it is not necessary to wait until it passes cleaning.You will always have a decent supply of water for the day.Approximately 15 liters, which is a lot.By the way, the water does not stagnate, and charcoal bag will last for several years.

Dimensions water filters may be different.If you need to quickly clean some water, you can make another cartridge filter using the purchase.So you can save money on buying a pitcher, especially if you often move from one place to another.Homemade Filter help out on business trips, on vacation, in the country.

To manufacture the filter you need to prepare the following:

  • filter;
  • plastic bottle 2 L .;
  • scissors.

Stages of water filter:

  1. need scissors to cut the bottle into 2 parts.The upper part of the cone will remain with cover.Next
  2. bottom of the filter should be inserted in the first part of the bottle (with the neck) so that the filter is "sitting" very tight.So you can decide where you want to cut the high part (neck).Scissors cut along the marked lines.Now you have 3 pieces of plastic bottle plus filter.The top of the bottle with the cap will not be needed.
  3. collect water filter: the top of the bottle (middle) set filter, narrow down.
  4. We put this structure in the conical part of the bottle and carefully presses.
  5. All water filter is ready, it remains to test the device by pouring a little water.

next version of homemade cartridge for water purification more interesting, because we do not only fully water tank, but the filter itself.

To do this, prepare the following:

  • canister of water (capacity of 5 or 10 liters);
  • 3-liter glass bottle;
  • fine river sand;
  • charcoal or activated charcoal;
  • gauze or cotton (you can take the cloth).

How to make your own filter:

  1. Cut the bottom of a plastic bottle in.The cover hot awl make holes.
  2. turns the bottle upside down and laid in a sequence filter elements: first, the fabric, gauze or cotton, then charcoal and the last layer - river sand.
  3. In this position without turning our homemade filter insert into the neck of a glass jar.
  4. Now you can see how the filter works.To do this, fill it with water (can be covered with a homemade device cut bottomed) and look forward to when it passes through the sand, coal and cloth.Try the water and enjoy its taste.
