Technofilter solutions for water sector

  • mechanical particles removal
  • prefiltration (including systems precede reverse osmosis units)
  • removal of colloidal particles
  • sorption purification
  • depyrogenation of pharmaceutical class water solutions
  • clarification
  • microbiological stabilization
  • sterilizing filtration

Membrane filter cartridges are used as a part of sewage treatment plants, units, individual portable devices for obtaining disinfected drinking water supplied to the Ministry of Defense, the Ministry of Internal Affairs, and the Ministry of Emergency Situations of Russian Federation.

Industrial filtration

Sterilizing filtration



"Technofilter" produces a wide range of sterilizing filters in the form of standard filter cartridges and  capsules based on various membrane materials:

- Polyamide (Nylon) is characterized by high filtration rates and wide chemical compatibility. It is used as a membrane material for EPM.K - / 020

- Polyamide (Nylon) with Z-potential as a membrane material for EPM.K + / -020 is used for sterilizing filtration with pyrogenic control for removing viruses from water systems.

- Polyethersulfone has a wide chemical compatibility (pH = 1-14), high temperature resistance and throughput, low sorption with respect to proteins, enzymes and proteins. The pronounced asymmetric structure and the increased total porosity of the membrane ensures reliable removal of microorganisms at high flow rates using EPM-PS-020.

Prefiltration, clarification, sorption purification, water treatment


Prefilters of "Technofilter" have a different design and are based on various materials:

Membrane prefilters:

EPM.K is a prefilter with a polyamide membrane.

EPM.SK is a prefilter based on polyamide membrane combined with a micro fiberglass prefilter.

EPM.PS is a prefilter with a polyethersulfone membrane.

EPM.FG is a prefilter based on hydrophilized fluoroplastic membrane (PVDF).

Pleated prefilters:

EPVg.P is a universal pleated filter cartridge based on polypropylene microfibers of increased density.

EPV.S is a pleated filter made of 100% microfine glass fiber.

EPV.SC is based on a pleated filter material made of microfine glass, cellulose and polypropylene fibers.

EPNS.P is a full metal filter cartridge used for process water filtration at high temperatures.

EPNS is a pleated filter made of metal mesh for pre-filtration processes of highly contaminated solutions,  process water.

Unpleated prefilters:

EPV.P is prefilter made of multiple polypropylene layers (wound or woven), bonded by air-extrusion method.

EPS.P is a sorption filter cartridge for sorption purification.

Filters integrity monitoring


Technocheck® is an automatic integrity test device for non-destructive testing of filters’ integrity. It is  used to monitor the integrity of the membrane sterilizing filters used at the final stages of filtration processes. The integrity of the filters and biological safety is controlled through the checking of diffusion, bubble point and pressure drop values, and for hydrophobic materials - a water intrusion test. The results of these tests are correlated with the Bacteria Challenge Test. 

In this section, we observe only the main technological processes, where our filtration equipment is successfully used. The choice of equipment, as a rule, is multivariate, and depends on specific conditions of the production process. The section Products describes the main recommendations for use for each product type. As each process is unique and requires an individual approach, please contact technical specialists of Technofilter to make a decision on selection of filtration equipment.
