Water-treatment filters

Industrial filters for water and other medium treatment

Industrial water-treatment filters are used in the flow charts of various industrial enterprises, as well as in the energy sector to produce boiler feed water.

Used in technological schemes of various industrial enterprises and for boiler water preparation in the energy sector

Industrial water treatment filters for water purification are vertical cylindrical steel devices with elliptical or torospherical stamped bottoms. The water filter housing can have a flange connector for easy and safe application of anti-corrosion coating. In the lower part of the housing, there are supports for mounting filters on the foundation. The upper and lower drainage and distribution devices are installed inside the housing. The filter package also includes piping with stop and control valves and instrumentation (pressure gauges).

Industrial water treatment filters are manufactured in accordance with the requirements TU (technical conditions) 3683-009-33513134-2012 "Water treatment filters for thermal power plants and industrial energy sector", effective from 01.08.2012.

Industrial filter tank machine for water filtration (FIPa)

Designed for use in water softening and desalting schemes at water treatment units of power plants, industrial and heating boilers and other facilities.

Depending on the filter media ion-exchange filters are divided into:

• cation-exchange filters designed to remove cations (Ca2+, Mg2+, Na+) from water during sodium-, hydrogen-, or ammonium- cation exchange;
• anion-exchange filters designed to remove anions (SO42-, Cl-, Hco3 -) from water during OH- or chlorine- anion exchange.

Depending on the place in the technological scheme of the water treatment units, there are:

• parallel-flow ion-exchange filters of the first stage (FIPa I);
• parallel-flow ion-exchange filters of the second stage (FIPa II).

Counter-flow ion-exchange filter tank machine for water filtration (FIPr)

Designed for use in water softening and desalting schemes at water treatment units of power plants, industrial and heating boilers and other facilities. Like parallel-flow filters, counter-flow filters are divided into cation-exchange and anion-exchange filters depending on the filter media. The difference from FIPa filters is that the regeneration of the filtering medium is performed in the direction opposite to the treated water flow. Depending on the design, counter-flow filters are divided into:

• counter-flow filters with hydraulic clamping of filtering medium layers;
• counter-flow filters with mechanical clamping of the filtering medium layers.

Vertical clarification filter tank machine (FOV)

Designed to remove suspended impurities of various dispersity from water. They are used in schemes of water treatment units for various purposes. Depending on the number of filtration chambers, vertical clarification filters are divided into:

• one-chamber filters;
• two-chamber filters (FOV 2K);
• three-chamber filters (FOV 3K).

Sorption carbon filter tank machine (FSU)

Designed for deep cleaning of recycle condensate from highly dispersed oil and oil residues, as well as for cleaning natural waters from organic pollutants, removing tastes and odors.

Mixed-bed ion-exchange filter tank machine (FISD)

Designed for use in desalting units and condensate purification units in power plants. Water filtration in these filters is carried out through a layer of special ion exchange charge consisting of a cationite and anionite mixture. Depending on the method of regeneration mixed-bed ion-exchange filters are divided into:

• mixed-bed ion-exchange filters with internal regeneration (FISDVr);
• mixed-bed ion-exchange filters with external regeneration (FISDNr).

Regeneration filters for water-treatment and condensate-treatment facilities (FR)

Designed for ionite charge regeneration of mixed-bed ion-exchange filters with external regeneration (FISDNR).
Regeneration filters are used in water treatment and condensate purification units of power units of thermal and nuclear power plants.

Iron and manganese removal manganese greensand filter system for drinking water treatment (FUZH)

Designed to remove iron, manganese and hydrogen sulfide from water. They are used in schemes of water treatment units of various purpose.

Precoat filters (FN)

Designed for cleaning low-turbid and low-color liquids from the smallest mechanical contaminations. They are used in schemes of condensate purification, sugar syrups, milk, beer, wine, oils, etc. cleaning.
Depending on the filtering medium precoat filters are divided into:

• ion-exchange filters (NIF)
• cellulosic filters (NTSF);
• perlite filters (NPF).

High Quality Irrigation Equipment Disc Filter

Designed for purification of water and other liquids from mechanical impurities.

Depending on the purification system disk filters are divided into:

• automatic filters;
• semiautomatic filters;
• filters with manual control.

Material:

• plastic;
• metal;
• stainless steel.

Automatic Screen Self-cleaning Filter for water

Designed for mechanical purification of water from various impurities.

Depending on the purification system, mesh filters are divided into:

• automatic filters with hydraulic or electric motor;
• semi-automatic filters with automatic drainage;
• filters with manual control.

Material:

• plastic (polyamide with glass fiber);
• carbon steel;
• stainless steel.
