Fine water filter





Nowadays, much attention is paid to the quality of the water consumed, because the tap water that comes autonomously into the house from a well or a centralized water supply system contains a lot of mechanical impurities. They slowly kill a person, increasing the load on the body, reduce the life of almost all household appliances. In an effort to please consumers, manufacturers saturated the market with various types and types of purification systems, including a fine water filter. In the article we will tell you how thin water purification is carried out and advise how to choose a modern fine filter for plumbing.

Basics of coarse and fine water purification

The process of water purification using special devices is called filtration. All contaminants in water can be divided both by chemical composition and physical size. Of course, completely purified water will not be ideal, since it will lack the necessary mineral elements, but an excess of various harmful chemical compounds in the water is not safe.

That is why there is a need for filters with various properties.

Rough cleaning

By installing a coarse cleaning device in a hot and cold water supply system, it is possible to significantly reduce the amount of mechanical impurities, sand, rust, abrasive particles and insoluble suspensions.

Basically, such systems are implemented in the form of a mesh made of stainless steel or non-ferrous metal, which retains larger impurities than the diameter of the mesh cell.

Important! The principle of operation of such filters is uniform, but they differ in the type of the main element, form, method of cleaning and the method of insertion into the water supply.

Fine water purification

By installing a fine filter, you will get excellent water quality, without organic compounds, chemical elements, heavy metal compounds, odorless, or even without some microorganisms.

Water of the required quality is obtained by fine filters. The filter for fine water purification consists of a housing and a main working element.

The material from which the device body is made affects the cleaning process and the properties of the resulting water. Options may be as follows:

• Sorption material (aluminosilicate or activated carbon).
• Reverse osmosis membrane.
• Ion exchange resins.

Important! Filters must be changed periodically. The frequency of cartridge replacement is usually indicated by the manufacturer and depends on the time of use, on the volume of water passed through.

The fine filter can be installed both on the general water supply system, purifying water for all residents, and on a separate branch of the system. A stationary filter can be installed and only drinking water in the apartment can be treated.

Characteristics and operation features of fine filters

To choose the right filter for fine water purification and correctly install it, consider the following points:

• These devices are very sensitive to pressure drops.
• Devices are sensitive to temperature extremes.
• Such devices require regular servicing.
• Fine filters have a limited service life.

In addition, consider the following points when mounting:

• It is strictly forbidden to violate the integrity of the flask and cartridge, which contains the active material.
• The fine filter must be installed only after installing the pre-cleaner.
• It is necessary to install the system as close to the consumer as possible so that there is no repeated water pollution.
• Do not use appliances designed for cold water when cleaning hot water, as they cannot withstand high temperatures.

The choice of a cleaning system is always made for a specific purpose. Of course, it’s impractical and economically unprofitable to clean all the water supplied to the house to a drinking state. Usually adhere to such conditions:

1. The most common strainer or bulb filter can be installed on the inlet pipe of hot or cold water to get rid of large particles and impurities.
2. If you need drinking purified water, then use a multi-stage fine-purification system, and put out a separate tap for its supply.
3. To protect plumbing, you can use fine filters that reduce the hardness of the water.

Mechanical filters

For cleaning with low requirements, filters that delay various contaminants are suitable. Options may be like this.

Woven filter

The device is a cylinder, with a rope or tow wrapped around it. Cleaning takes place in a layer of material that traps foreign particles, insoluble salt crystals and metal oxides. A fine filter for plumbing is used.

Advantages of the tissue system:

• Universality.
• Low cost.
• Acceptable work resource.

Important! Most additives are found in hot water, because such additives allow water to be as long as possible hot. Therefore, if you notice that the drum tissue has changed color, then the device must be cleaned or replaced. To do this, fill it with water and boil until it turns white.

Sorption type filters

The device is a mesh cylinder, which is filled with mineralized chips. Such a device protects against chemical salts and various compounds. Some types of aggregates are a complex of sorbents based on activated carbon and aluminosilicates. Cleaning is carried out at the level of interaction of various particles with the crystal lattice of the filler.

Fillers that use zeolite and shungite work on the same principle:

1. Zeolite is actively used in municipal and industrial systems for the treatment of recycled water. It is a proven reagent.
2. Shungite is a relatively new mineral aggregate and its properties have not been fully explored.

Important! Such filters have a significant resource, but they also need to be changed when plaque appears on the walls. You can restore the device’s operating properties for a while by flushing.

Application

Install a fabric or mesh filter for plumbing with high throughput at the entrance to the water supply system of a private house. It will reduce the load on other cleaning devices installed on other sections of the network or on household equipment.

Filters with ion exchange resins

Such a filter for fine purification of water can significantly reduce its stiffness. The main working element is a container, inside which are granules of ion-exchange resin. The flow of water passing through the granules washes them, as a result, a reaction occurs to replace calcium in salts with sodium. Sodium salts do not cause sedimentation on the walls of pipelines, as well as on the walls of heating devices.

The body of the product is made of plastic or steel.

Important! The performance of ion-exchange systems depends on the composition of water, room temperature and the quality of ion exchangers. The effective life of such aggregate is limited and depends on the volume of water passed through. The work item must be replaced with the cartridge.

Multi-Stage Systems - Ultrafine Cleaning

Sometimes in the filter unit several types of filler are used. Purified water is passed through them sequentially - such a system is called a cascade or cascade filter. In such a multi-stage system, after mechanical cleaning, water is treated with ultrafine cleaning elements.

Working components are made of various materials capable of solving the problem of separation of harmful compounds. In addition, they differ by the principle of exposure to impurities:

• The first stage - is responsible for the purification of water from mechanical impurities. As a result, the water becomes transparent.
• In the second stage, water passes through an ion exchange cartridge. As a result of this purification, the chemical composition of water changes: all oil products, iron, chlorine, pesticides and nitrates are removed. When boiling, such water does not form scale on the walls and heating elements of electrical appliances.
• The third stage of purification is provided by pressed activated carbon, which conditions the water flow. As a result, drinking water becomes perfectly pure and crystal clear, acquires a pleasant taste and smell.

Important! Install the three-bulb system under the sink. The interior of the kitchen will not suffer, and to remove purified water, install an additional faucet at the sink.

Reverse Osmosis Filters - Molecular Purification

Modern technologies have allowed to create the most advanced fine water purification system. Reverse osmosis filters represent a thin film semipermeable membrane with a pore size of only 0.0001 microns.

Only a water molecule is able to seep through the pores of the membrane; therefore, it is not surprising that the transmitted tap water is purified from 99% of impurities.

Important! Before water enters the fine filter, it is subjected to several degrees of purification, otherwise, such elements would quickly fail.

Act

A high level of cleaning allows you to remove not only dissolved contaminants, biological residues, but also pathogenic bacteria. Reverse osmosis systems put an insurmountable barrier to all harmful substances contained in water, such as:

• Magnesium.
• Mercury.
• Arsenic.
• Strontium.
• Nitrates and nitrites.
• Asbestos.
• Cyanides.
• Fluorine.
• Lead.
• Iron.
• Chlorine.
• Sulphates.
• All kinds of bacteria.
• Viruses.

Principle of operation

This perfect cleaning takes place thanks to five steps:

1. At the first stage, a cartridge for mechanical cleaning of impurities and suspensions (15-30 microns) works.
2. At the second stage, activated carbon “enters” the work, which removes chlorine, chlorine compounds and gases.
3. At the third stage, there is a fine purification of water (1-5 microns), as well as post-treatment with pressed activated carbon.
4. At the fourth stage, the reverse osmosis method works.
5. The carbon post-filter finishes.

Important! The membrane filter is not installed on the supply piping, as it works as an independent element of the system. The productivity of such a device is low, since this is due to the duration of the cleaning process, however, the service life is significant and significantly exceeds the operating time of other systems.

Minuses

The disadvantages of this system include:

• High price.
• Replacing a life-time membrane is also more expensive than all other filters.
• As a result of purification, useful substances are also removed, although some plant models are additionally equipped with mineralizers and ionizers.
• The pressure in the water supply system must be at least 3 atmospheres.

Important! If your water supply system has a water pressure of less than 3 atmospheres, then purchase a reverse osmosis device with a pump.
