Water filters for wells: taking care of health

Drink water from an untrusted source is prohibited. If a one-time ill-advised move can cause a momentary disruption of the body's condition, then the constant use of water and undesirable impurities can significantly affect health person. Water filters for wells, properly selected and installed, will make drinking source is not only safe, but also useful.

Possible types of contamination of drinking water from underground sources

Composition downhole water depends on the depth of the reservoir and types of ground through which it passes. Rely solely on the taste, color and odor in determining the quality is not enough. Conducting chemical water analysis in a laboratory is required. The main types of pollution and sanitary indicators of non-compliance may be considered:

1. The increased iron content. This is a problem of almost all neglubinnyh sources. Water may be red color and a metallic taste. But even in clean at first glance, the water concentration of the trace element can be excessive.
2. The presence of hydrogen sulfide. A significant excess of this substance in the composition of water produces an unpleasant odor. But even if the amount is small, this chemical compound can be toxic.
3. High level of mineralization. This salt content. Their surplus gives the water a salty flavor. Such water poses a serious health threat, especially to people with hypertensive disease.
4. Rigidity. calcium and magnesium content of the total of the figure. It causes the formation of stones in the human body, scum on the heating devices.
5. Nitrate concentration. It is not determined by the taste, a detrimental effect on the cardiovascular system. Especially vulnerable children.
6. Mechanical impurities. May fall during the well installation. This crumbling soil, residues of synthetic materials used in sealing, lubrication.
7. Bacteria and viruses. It arises as a consequence of the decomposition of biological materials. It is also possible to penetrate into the water during drilling.

Useful advice!If laboratory studies have shown the presence in water of increased amounts of certain minerals or the presence of harmful bacteria - cleaning is required. Failure to do so after prolonged use of the fluid can cause serious harm to health, up to irreversible processes.

Water filters for wells: Key principles of operation and

The filtration system is installed, depending on the type of hole and the surrounding soil. From the latter depends on the material used to create the frame filter. This may be steel, polyethylene, polypropylene and others. To the cleaning process to be effective, it is necessary to calculate the duty cycle. This value, which is obtained by dividing the square holes on the working surface area and multiplied by 100%. Received number must not be less than 25%.

There are several types of filter systems. The main are the following:

• mesh;
• tube with a slit or circular perforations;
• gravel;
• wire (frame-rod and tube).

Strainers are mounted in holes drilled into the unsteady, unstable rocks. Is made mainly of steel, is mounted directly on the depth. Depending on the particle to be filtered, the mesh can be single-layered, multilayered, with square cells and T. D. The drawback of this system - the rapid clogging. However, the grid is quite easy to extract for cleaning or repair. The range of sizes of cells - 0,12-3 mm².

Tubular slotted and round apparatus optimally applied in cases when the water is pumped out of the pebble gravel and rocks. The filter is a tube with a circular perforation or multiple slots, which are able to detain particles of size up to 10 mm.

Wire filters are divided into two types: frame-rod and tube. Frame-rod devices have a structure from bar steel rods, tubes of casing and casing belt of iron. In such a wound wire frame. Tubular Wirewound barriers have a frame made of perforated tubes and a coil with stainless steel wire. The wire helically wound around the carcass, creating long slits through which filtered particles of sand and gravel. Wire filters are highly efficient. However, there are some drawbacks: expensive equipment, it is difficult to clear the backlog of mechanical particles.

The most reliable and inexpensive water treatment devices - gravel filters. They represent a layer of gravel or coarse sand in contact with aqueous reservoir. Such filters can be ready to go down the well. Gravel is poured into the annulus. Ready filter layer should have not less than 30 mm, the filling - not less than 50 mm. This system is distinguished by the durability, availability, cleaning and environmental friendliness.

Useful advice!The installation of any type of filter system is better to make the participation of a specialist who will correctly estimate the soil aquifer.

Water filtration systems of the well: target orientation

Depending on the chemical composition of water may require the use of not one but several filters, that is, the creation of the filtering system. Each purifying device performs its task and has a definite place in view of the cleaning sequence as a whole. There are a lot of filters, which differ in orientation activities.

Reverse osmosis filters. The flow of water under pressure is directed onto the membrane with low permeability, which holds only pure water. Harmful substances in this case do not penetrate into water. The basis filters for iron removal from a well is used a reverse osmosis system. Iron is precipitated as rust, is delayed by passing through the membrane. A common problem - the need for water purification from lime (calcium salts). This impurity in excess extremely harmful for the human body. Filters from lime also operate through the membrane system.

Obezzhelezivateli. The basis of this purification system - backfilling. It accelerates the chemical reaction wherein iron and manganese are oxidized and precipitated, without falling into the water feed stream. This purification process may be mechanical, but there are automatic methods.

Nonchemical obezzhelezivateli. The basis - the process of electrolysis. This is one of the most effective water filters from rust, but quite expensive. In addition, its installation is fairly problematic.

Softeners. It filters water softener hardness. The purification process is based on ion exchange. The water passes through the resin, which changes the calcium and magnesium ions with sodium ions. The ion exchange resin is regenerated.

Carbon filters. Coal performs sorption function. After passing through the carbon bed water exits transparent odorless. In this way cleaning can be carried out by hydrogen sulfide and water from mechanical impurities.

Strainers. Strainers clean water wells or for any of the water supply system operate on the same principle: the various particles of debris and metal precipitates are delayed using the grid.

UV filters. Destroy bacteria and viruses. Ultraviolet water filters are placed inside the housing with ultraviolet lamps. The flow of water passing through such a system becomes safe and decontaminated.

Useful advice!This filtration system makes sense to set in if the iron is the only substance to be removed. In other cases, this process will be unprofitable.

Sequence drinking water purification process

With rare exceptions, the water needs to be cleaned from several elements, so dependable and gives the desired result is to install speed system. In the course of its activities have identified a number of stages:

1. Chemical analysis of the water, which gives an idea of ​​the composition and degree of concentration of harmful substances and organisms. Set level of salinity, hardness, determined by organoleptic component.
2. Carried rough cleaning, it is removed during the different particles (sand, pieces of the scale) which may harm the work of other types of filters.
3. Metals are removed, the presence of which can also be harmful to health and the work of other filters.
4. Removal of salts - softening water, in which process the liquid is cleaned of magnesium and calcium salts.
5. Fine purification, the purpose of which - the removal of organic impurities, improve palatability.
6. Decontamination - the destruction of bacteria and viruses.

Useful advice!Failure to comply with at least one of the cleaning steps makes water unfit for human consumption.

How to select the desired filter for water wells

There are two main reasons why the need to install water filters from the well:

1. Bringing water-composition in the state corresponding to the quality standards of consumption.
2. Protection equipment used for feeding and cleaning, from damage by harmful impurities.

Therefore, to buy a filter for wells, corresponding to the conditions and requirements of the proper operation of obtaining high-quality water from these necessities, and to take seriously. The primary objective - purpose: what and how to be cleaned. The second, no less important issue when choosing a cleaning device: it should be noted whether the conditions provided for its maximum productive work. There are common characteristics of the objective to be met by any filter:

1. Anticorrosion qualities. The conditions under which fits any filter, contribute to the appearance of corrosion. Therefore, should pay special attention to the material of construction of the filter unit.
2. High capacity. It depends on the nominal specifications of the treatment apparatus and the accuracy of calculation of the matching filter hole size.
3. Strength. It ensures compliance with the quality and characteristics of the filter assembly of its operating conditions.

Useful advice!When selecting a filter, you must follow the rules of rational choice. For example, expensive and durable wire set as filter well in sand is not suitable. It will last for a long time, but will require constant cleaning.

Stages of purification of water from a well in a country house

In the implementation of the installation of water treatment in the country house, you need to follow the traditional algorithm:

The need for analysis. Especially cleaning the well and the well. Removal of sand and silt. Carrying out cleaning by hand.

• an in-depth analysis of the chemical composition of water;
• identification of the substances whose concentration is higher than normal;
• system selection and design;
• testing of the equipment.

Installation of water filtration in a private home, you can consider the following example. For example, in water exceeded the amount of chlorine and hydrogen sulfide dissolved (ferrous) iron. You must buy a filter for the purification of water from wells, performing rough water treatment. Then aeration column need for water oxygenation, accelerating the oxidation reaction, as a result of which the iron would be ferric and precipitated. The filter material placed in the column to purify the water from dissolved gases.

This level of cleaning will make the water suitable for industrial purposes, safe for household equipment. If you want to bring the composition to the appropriate nutritional standards need to install additional filters.

water purification system of the villa of the well is of no fundamental differences from the water purification system of a country house. Filter to give the rough purification of water as required since without it a further filtering system impossible. His absence could affect the operation of the pump, to promote breakage and wear of the equipment. The remaining filters for water from the well to give have standard specifications (depending on the application).

Widely used in the cottages as a wastewater treatment plant septic tanks for water. The principle of operation of such filters to give the following: a reservoir (via the upper feed) moves down the pipe water. It reaches a shield located below the pipe and use it to change direction - rises. In passing through the edge of the water has been purified state because the contaminants remained below which precipitated.

The bottom of the tank often has a conical shape, at least - a pyramid, as in the last dirt is hammered into corners, so that the fermentation begins, it runs through iloprovod worse.

Useful advice!To sump for water to function properly, it is sure to monitor the status of the filtered substances and hit them in the place of gathering. Sometimes it requires manual cleaning, since waste can be compacted.

Filter for wells with their own hands: the materials and sequence of

The complexity of installation and the high price of the finished filtering equipment often leads to a desire to understand how to make a filter for wells on their own. It's not hard. In addition, the cleaning device, created by your own hands, has a number of advantages:

• used available materials;
• the system does not require much physical effort;
• It does not require large financial investments;
• qualitatively cleans large impurities;
• removes substances that create unpleasant smell and taste.

The main disadvantage of homemade water filters is the impossibility of biological decontamination. This water must be boiled.

Simple and effective home design

How to make a water filter? This will require:

• charcoal;
• cotton fabric flap;
• plastic screw cap bottle.

Create a filter layer follows: preparing activated carbon - is crushed into particles of 4-5 mm, then boiled in water for 5-7 minutes, cools and is placed into the bottle (filled with one third) .In tube bore holes about 3 mm in diameter, in the bottle neck the fabric is laid, the bottom cut off. This filter is done in haste, but the water from it flows clear.

Homemade affordable water purification system for the well

Optimal and accessible design - bottom filter. For him everything you need:

• river pebbles of medium size;
• gravel;
• gravel;
• sand;
• black stone - schungite;
• zeolite as a sorbent.

It is necessary to produce panels of wood or other suitable material (stainless metal, polypropylene), wrap the geotextile fabric and lowered into the well. If the bottom of the clay, the necessary flow filter for sandy bottoms - the reverse. When the direct device stacked filter system first major fraction, then smaller. Finishing coat - sand. Backwash filter begins with the laying of sand and stone finishes.

The thickness of each layer for each of the two filters should be at least 20 cm, and the layers should be at least three. Despite the simplicity of installation availability and efficacy, these filters have a disadvantage: they require almost annual cleaning. Better to replace all the layers, but if this is not possible, make sure you need to lay new sand and stones must be thoroughly washed and disinfected in boiling water.

Useful advice!Building rubble - easily accessible material, but using it is not recommended, since it needs a major cleaning.

A device for cleaning the well water

When you create a treatment system will need the following materials for the wells:

• pipe, preferably polypropylene with thick walls;
• wooden plug;
• net with fine mesh.

The only time-consuming process to create the well screen - punching. Holes were made with a drill and drill at an angle of 60 °, staggered at a distance of 2-3 cm. Perforation should occupy a fourth part of the pipe. The lower part turns into a grid that must be securely fastened, as the impact of water can damage the structure. Top tube is stoppered. Passing through the filter, larger particles fall into the sump, small mesh delayed. Most effectively operates a filter water from a well after the sand.

Water filters for wells: manufacturers and price

Buy a water filter from the well can be from different manufacturers, the market is fairly saturated. The right decision when choosing - rely on products whose quality is tested by time. production leader of the filter devices in the global market - Honeywell. This is an American brand name, which is used by manufacturers in many countries, including Russia and China. Products are resistant to corrosion processes, durability.

Compete up filters manufactured by the Israeli company Arkal. They are eco-friendly, easy to install. In addition, the company is well organized repair service.

Products Rusfiltr domestic company is also competitive. The filter function of the products are quite high, the product quality. Carried out both coarse and fine cleaning. There is a difficulty in maintenance and repair.

Popular cleaning system of the joint Russian-Italian production Valtec. The line presents a variety of products, including the obliques, self-cleaning, large- and small-sized filters. The use of high-quality alloys (brass, bronze, stainless steel) extend their service life.

The range of the online store "Three wells" - water filters foreign and domestic manufacturers. To filter for water from the well of lime are softeners, iron removers, carbon, UV, the aeration installation, integrated system.

Price filter water from a well is dependent on the quality of material used and the producer. The cost of single-function types ranges from 20,000 to 40,000 rubles. When the two kinds of filters, cleaning the price is increased by one third - 27000-55000 rubles. The cost of complex systems comes to 100,000 rubles. Separate installation of foreign production exceeds the price level.

The main reasons for poor performance of the water purification filter wells

Unfortunately, there are cases when after use in water purification are unnecessary impurities and taste quality is poor. The reasons for this result may be different. Among the common are the following:

• incorrectly matched filter types;
• their number is insufficient;
• errors in sizing;
• leaking closed sump;
• parts of the filter used made of material that does not resist corrosion.

Useful advice! When selecting a filter all the conditions necessary to take into account the performance and well - and do it better with a specialist. Certain types of filters can not be removed for repairs without damaging the casing. In such a situation we will have to spend a lot of effort, time and money to restore the functioning of the source.

How to reduce the hardness of water, make it transparent, tasty and safe to use - this is the task for the filter units. But even the most modern equipment with precise electronic control can not cope with the work without human intervention. The ability to competently, correctly use a filter - the key to success in the process of water purification. Human health depends on the quality of water consumed.
