WHY WATER TREATMENT IS NEEDED

DO I NEED A WATER PURIFICATION SYSTEM AT ALL?

The question of water purification arises as if by itself if the water coming from the water supply system or the well is muddy, has a yellowish-brown color, and odor. It is much more difficult when the water is completely "normal" by all external signs - it seems like there is no reason for concern. Meanwhile, world experience shows that the cost of water treatment is on average 5-7% of the value of the house. And this is no coincidence. Even outwardly safe water may contain such a “bouquet” of dissolved and undissolved impurities that it is sometimes simply unsafe to use it. Unambiguously judge the quality of water is possible only after full chemical analysis. Problems are removed by purification systems, or more correctly, water treatment.

Water purification from 5 contaminants - hardness, iron, manganese, ammonium, and organics.

Such uniformity of pollution determines the main task of water purification from the well: simultaneous softening, iron removal, removal of manganese. That is why comprehensive water treatment is perhaps the most popular in the Ukrainian water treatment market. Complex cleaning allows you to effectively soften the water, remove iron, manganese, as well as organic impurities and ammonium using only ONE filter thanks to a special filter filling.

Perhaps the most difficult task of water treatment is the removal of iron, water purification from manganese. The effectiveness of deferrization is determined by a number of factors: the pH value of the pH, as well as the content of anions, oxygen, organics, hydrogen sulfide. In addition, iron can be found in water in several forms, including hard to remove ones. So, in the well most often it is divalent and therefore dissolved, inorganic iron. In addition, organic divalent, as well as colloidal and trivalent, sedimentary forms may be present.

Complex water purification efficiently and effectively removes all of the above forms of iron: dissolved, colloidal and organic, regardless of pH, the presence or absence of chlorine, organics, hydrogen sulfide, as well as the ratio of chlorides, sulfates and bicarbonates. Concomitant manganese is also removed along the way.

For complex water treatment, only the total iron content is relevant. Thanks to a comprehensive cleaning, deferrization, softening, as well as demanganization, have become simple and affordable. Integrated filters are reliable in operation, and in design and dimensions are identical to standard water softeners. The calculation of the filter performance is carried out under the condition of a linear filtration rate at the level of 20-25 m / h.

Long and uninterrupted operation of the filters is ensured by periodic and timely regeneration, that is, washing of the load, as a result of which the accumulated iron, manganese, stiffness ions, and other contaminants are removed and washed off into the drainage. The regeneration process consists of three parts: backwashing the load with water, washing with a solution of sodium chloride, and final quick washing. When these and other simple operating rules are followed, the loading of the integrated cleaning filter will last 5-7 years.

The universality of the technology, the ability to effectively remove all types of iron, regardless of pH and other factors, as well as the simultaneous softening of water, purification of water from manganese and filtration from organics and ammonium have led to the widespread use of complex purification. In turn, the compactness and cost-effectiveness of these filters allow them to be used both for water purification in cottages and apartments, as well as for commercial water treatment, for example, for hotels, restaurants, mini-manufactures.

Main water filters

Water purification with main filters

Water is not only the basis of all living things but also the basis for our civilization. After all, people always tried to settle closer to the water, because the largest megacities of the world grew on water: London, New York, Moscow, Tokyo, and others. Water is needed not only to meet natural needs, but also for hygiene.

A mechanical water filter plant is a fairly simple device that traps foreign bodies, dirt, rust, grains of sand, fine debris, and organic particles. First of all, such filters protect household appliances (dishwashers and washing machines, plumbing for the bathroom and kitchen) from damage by small debris that is contained in tap water. At first glance, the water may seem quite clean, but do not forget that before you get to your crane it passes kilometers of old rusty pipes and as a result becomes practically unsuitable for further use in domestic needs. Therefore, a mechanical water purification filter is not a luxury, but a necessity. You can buy the main water filter in our Water Service store.

Main mechanical filters are divided into the following types:

Coarse filters (operate in the range from 20 to 100 microns);

Cartridge filters (or cartridge);

1.       Filters of the filling type;

2.       Mesh washing;

3.       Disk wash filters.

4.       Cartridge Line Filters

The basis of the cartridge filter is a collapsible metal or plastic flask into which the cartridge is placed - a disposable replaceable element. Such filters have a filtration range of 20 to 50 microns. Cartridge printers are distinguished from washing printers by a single-use filter element, that is, it will not work to clean and reuse it.

But how to detect a clogged filter or not? Quite simply, you will notice that the pressure of the water in the tap will decrease significantly, so it's time to replace the cartridge. Replacing is quite simple, for this, minimal knowledge and skills are enough. how often the cartridge will clog up is pretty hard to say because it depends on many factors, such as: the quality of tap water, its composition, worn pipes. Someone will change the cartridge once every six months, and someone every week.

Water strainers

Strainers consist of a housing and a fine mesh which performs the filter element. This is ideal for filtering water with a low content of mechanical particles. There are a lot of options for such filters, and the degree of purification depends on the size of the mesh cell. In case of clogging, it will not be necessary to disassemble and change such a filter; washing with a reverse water flow will suffice.

Disc Water Filters

Disc filters are designed for coarser water treatment. Outwardly, they are absolutely no different from the retina, but dense discs with longitudinal grooves are used as a filter element. Such filters combine reliability, unpretentiousness in operation and low cost of maintenance. Able to filter out both mechanical and organic particles. They are mainly used for water intake from wells. As in the case with strainers, if clogged, it is enough to rinse with a reverse flow of water.

The advantages of a disc filter over a mesh filter

Disk filters have several advantages:

1.       They are much easier to wash from particles and dirt accumulated inside;

2.       Unlike screen filters, disk filters are much more resistant to corrosion, which is especially true for areas with brackish water;

3.       Strainers are ineffective in treating water that contains fine fibers (such as wool). That is, the water purified using a disk filter will be better;

4.       Unpretentious maintenance, easy to repair;

5.       All components of the product are chemically neutral, do not affect the composition of water;

6.       Reliable, robust construction with relatively low weight;

7.       Not afraid of water hammer;

8.       A wide range of applications, such as a filter can be used to purify drinking both drinking and industrial water.

9.       Disc filters are more expensive than mesh filters, the higher cost is offset by a much longer work.

10.   Fill filters for mechanical cleaning

As the main filter element in the filling filter, synthetic granular material is used - foamed aluminosilicate. You can also clear a clogged backfill filter with a reverse flow of water. Such filters are able to cope with particles up to 20 microns in size, they can withstand code moments well, a stream of heavily contaminated water enters the water supply. Fill systems are the most complex of all the above, most models are equipped with an automatic control unit.

Such a filter works according to a rather simple principle: water under pressure enters the filter, passes through the filter material from top to bottom and is already cleaned of foreign bodies (sand, clay, rust, etc.) and enters the outlet port for further supply through the water supply.

Fill filters are installed in front of chemical water treatment systems. Ideally, in front of the filling filter, there is a disk or mesh filter, so you can achieve perfect water purification.

Drinking water filters

Today, the water that flows from our taps, roughly speaking, has not been drinking for a long time. The use of such water leads to the scale on a teapot and other utensils, poisoning the body with organochlorine (do not confuse it with free chlorine that wears off when the water settles), and the unpleasant taste of drinks and cooked dishes.

Nationwide, this problem is simply unrealistic to solve! The general ecological state of the prepared water sources is getting worse every year, and there is no doubt that the attitude to this problem will change.

Residents of high-rise buildings are forced to buy bottled (supposedly mineral and healthy) water, but given that the water market is crowded with water bottling plants, there is no escape from fakes, and manufacturers can preserve antibiotics for long periods of storage. It is worth thinking about its quality. But there is water and good quality, there are many well-known brands that supply water in 19 liters. bottles to your home, but first this water is extracted and purified by various methods including reverse osmosis.

Today, the reverse osmosis water filter is the most perfect and effective way to purify tap water and turn it into drinking water.

It is worth noting that the principle of operation of the reverse osmosis system is borrowed from nature, and consists in the following: a thin membrane, which is a film with fractions of very small sizes, is able to pass only water molecules, as well as some chemical elements dissolved in it, oxygen, hydrogen. And mechanical impurities, salts of heavy metals, harmful pathogenic viruses and bacteria remain behind the membrane.

To prevent membrane cells from becoming clogged with a variety of impurities contained in the water to be purified, the filter of the reverse osmosis system must have a water pre-filter (prefilter) with several stages of filtration. The first stage of filtration is the cleaning of mechanical impurities (sand, suspensions, rust, etc.), the second is the stage of chemical cleaning with a carbon filter of chlorine-containing and various organic compounds. If necessary, the prefilter can be equipped with the the third stage of cleaning - trapping small particles not exceeding 5 microns in size.

After the membrane, immediately before the drinking tap of purified water, there is a carbon post-filter. This is the last stage of purification, which is a guarantee of obtaining drinking water of impeccable purity.

Thus, it turns out to be unusually tasty, perfectly purified, healthy water, in quality and taste many times greater than the usual bottled water from the supermarket.

To increase the service life, productivity, and improve the quality of purified water, reverse osmosis systems have an auto-flushing device (water is supplied to the membrane under pressure for 20 seconds and begins to wash away particles accumulated on it).

If the pressure in the water supply system is small (less than 2 atm.) Or the water is taken from the tank, then the reverse osmosis system is supplemented by a pressure increase pump. With its help, the pressure rises to the level of 3.5-4 atm., Which is necessary for the normal operation of the filter. Note that the required pressure level is present in almost all water supply systems in large cities, so some filter models are equipped with a pressure increase pump.

The reverse osmosis system also comes with a storage tank for storing purified water and a chrome-plated drinking tap, which is installed on the sink next to the main mixer.

The carbon filter for water purification effectively removes:

1.       chlorine and its compounds;

2.       mechanical impurities;

3.       bacteria and germs;

4.       smell and turbidity.

The quality of the water purified through a charcoal filter is fundamentally different from the tap water supplied by public utilities. The carbon water filter compares favorably with compact dimensions and ease of installation. Most often, you can install it yourself, without resorting to the help of specialists.

Purification of water from chlorine using a carbon filter

Water from the city pipeline is heavily chlorinated. Therefore, many people suffer from irritations of the skin, while the condition of the hair and teeth also noticeably worsens. In such cases, a carbon filter is a real salvation. With the right choice of model and its proper installation, all of these problems will disappear from your life forever. Instead, your family’s immunity will be much stronger.

The big advantage of this device is its relatively low price. The carbon filter price is available for any category of the population. Moreover, it very effectively copes with any chlorine compounds. This treatment system is multifunctional and reliable.

Before you buy a carbon filter, familiarize yourself with its principle of operation. It is a small plastic vessel with a replaceable cartridge, which is filled with activated carbon. In this case, coal is initially specially treated. Inexpensive exchangeable cartridges can be easily replaced independently. The return on the filter is very high given the high cost of bottled water. The carbon filter is designed for several months of continuous operation. Depending on the quality of the water entering it, it can effectively last up to a year.

How to choose chlorine water treatment

Dechlorination of tap water is effectively managed by the following types of filters:

·         Cartridge type

·         Column type

·         Cabinet type

The most compact and cost-effective are carbon cartridge filters. But in their device, there is no material regeneration, so the cartridge needs to be replaced every six months. In this case, the cartridge type is inferior to other types in terms of cleaning speed.

The material for loading carbon column water filters is more durable and will last up to two years without replacement, and the material is automatically regenerated. However, column filters take up a lot of space, but the highest speed of water purification and high throughput allow them to be used for mini-production.

Carbon filters of cabinet type with automatic material recovery can function uninterruptedly for two years. Regeneration takes place according to an established cycle, depending on the quality of water and other factors. This filter is quite bulky in size, but it has a maximum degree of water purification compared to cartridge types of filters.

Mechanical water filters

Mechanical water treatment - removal of suspended solids (particles, sand, suspensions, rusts, etc.) from industrial and domestic wastewater. The essence of this method is to prepare water for physicochemical and biological treatment. Mechanical water purification filters are usually installed at the inlet of the filtration system, but depending on the project, they can be used with other elements of water treatment systems.

Filters for mechanical cleaning water

Multimedia filter media in the field of mechanical water purification has many advantages.

Physical properties allow reaching the level of mechanical treatment up to 5 microns.

Due to the large size of the filter particles and the deep penetration of contaminant particles into the loading layers, the pressure loss of the filter is reduced and the service life of the material is extended.

Due to the irregular shape, the multimedia download prevents the filtered impurities from sticking and blocking in the upper loading layer. Lightness provides low water consumption and greater expansion of the layer to remove mechanically filtered particles during loosening of the load. This combination makes multimedia loading highly efficient filter media.

When used in mechanical filters, it significantly reduces the capital and operating costs of purifying water from suspended particles due to low-pressure losses, high productivity, and low loosening water consumption.
