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.
Industrial water-treatment filters have cylindrical vertical vessels made of stainless steel with elliptic or torospherical stamped bottoms. The filter's vessel may have a flanged connection for easy and safe application of a corrosion-resistant coating. The lower bottom of the vessel is equipped with support legs for mounting on the foundation. The top and bottom drainage distribution assemblies are installed inside the vessel. Filter's scope of supply includes piping, check and control valves, and instrumentation (pressure gauges).
Industrial water treatment filters are manufactured in compliance with TU 3113-003-04688393-05 "Water treatment filters for heat and power plants and industrial energy sector", efficient from of July 1st, 2005.
Ion-exchange parallel-flow filters (FIPa)
Intended for use in the water treatment systems to obtain softened and demineralized water at central heating and power plants, industrial and heating boiler plants, and other facilities.
Depending on the resin charge used the ion-exchange filters are divided into:
Depending on position in the process flow chart water treatment filters are distinguished as follows:
Ion-exchange counter-flow filters (FIPr)
Intended for use in the water treatment systems to obtain softened and demineralized water at central heating and power plants, industrial and heating boiler plants, and other facilities. Similar to the parallel-flow filters, the counter-flow filters, depending on the applied resin charge, are divided into cation-exchange and anion-exchange filters. In contrast to FIPa filters, the regeneration of ion exchange resin occurs in the direction opposite to the processed water flow. Depending on design the counter-current filters are divided into:
Vertical clarifying filters (FOV)
Intended to remove the suspended impurities of various dispersion from the water. These filters are used in water-treatment facilities of various purposes. Depending on the number of filtration chambers the clarifying filters (FOV) are divided into:
Sorption carbon filters (FSU)
Designed for deep purification of a recycle condensate from highly dispersed oil and oil products, as well as for treatment of natural waters from organic pollutants, removal of taste and odour.
Ion-exchange mixed-bed filters (FISD)
Intended for use in the water demineralization and condensate-treatment plants at the electric power stations. Water filtration is performed trough the layer of specific mixed resin bed consisting of cation and anion exchange resins. Depending on the regeneration method, the ion exchange mixed-bed filters are divided into the following types:
Regeneration filters (FR)
Designed for regeneration of mixed-bed filters' resins with external regeneration (FISDNr).
Regeneration filters are used in the water-treatment and condensate-treatment facilities of the power units of thermal and nuclear power plants.
Iron removal filters (FUZH)
Designed for removal of iron, manganese and hydrogen sulphide from water. These filters are used in water-treatment facilities of various purpose.
Precoat filters (FN)
Intended for purification of low turbidity and low-colour liquids from ultra-fine impurities. Used in treatment of condensate, sugar syrups, milk, beer, oils and etc.
Depending on the applied filtering material the precoat filters are divided into:
Intended for purification of water and other liquids from mechanical impurities.
Depending on the treatment system used, disk filters are divided into the following types:
Depending on material of construction:
Designed for mechanical water cleaning from various impurities.
Depending on the treatment system used, strainers are divided into the following types:
