Basic technologies Technofilter in the water sector


  • mechanical particle cleaning
  • prefiltration (including in front of reverse osmosis systems)
  • removal of colloidal particles
  • sorption cleaning
  • depyrogenation of water objects of the pharmaceutical class
  • clarification
  • microbiological stabilization
  • sterilizing filtration
  • removal and concentration of viruses from water bodies



Membrane filter elements are used as part of sewage treatment plants, plants, 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 the Russian Federation.


Industrial filtration


Sterilizing filtration


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


- Polyamide (Nylon) is characterized by high productivity and wide chemical compatibility as a membrane material for EPMK - / 020


- Polyamide (Nylon) with Z-potential as a membrane material for EPMK + / -020 for sterilizing filtration with pyrogenic control , to remove viruses from water systems.


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





Prefiltration, clarification, sorption cleaning, water treatment


Prefilters of "Technofilter" have a different design and materials:




EPMK is a prefilter with a polyamide membrane


 EPMK - prefilter with polyamide membrane with a layer of fiberglass


  EPMMS - a prefilter with a membrane of polyethersulfone


  EPM.FG is a prefilter with a membrane of hydrophilized fluoroplastic (PVDF)




 EPVg.P is a corrugated universal polypropylene filter of increased density


 EPVS is a corrugated filter of 100% microglass fiber


 EPVC is a corrugated filter made of glass, cellulose and polypropylene microfibers


 EPNS.P is a corrugated all-metal stainless steel filter for process water filtration at high temperatures.


 EPSC - corrugated stainless steel filter for pre-filtration processes of highly contaminated solutions, process water.



wound or fiber, bonded by air-extrusion method


Sorption-filtering  EPSP for sorption cleaning.



Filters integrity monitoring


"To monitor the integrity of the membrane sterilizing filters used at the final stages of filtration processes, automatic tester devices for non-destructive testing of filter integrity of the Technocheck®. The integrity of the filters and biological safety is controlled through the determination of diffusion, bubble point and pressure drop, and for hydrophobic materials - a water intrusion test. The results of these tests are correlated with the Bacteria Challenge Test.




In this section, we confine ourselves to the main technological processes, where our filtration equipment is successfully used. The choice of equipment, as a rule, is multifaceted, and depends on the specific conditions of the production process. In the section  The products for each type of product are given the main recommendations for use. Since each process is unique, these recommendations should be taken into account as a starting point. We ask you to consult with technical experts of "Technofilter" on application for making a decision on the choice of equipment for a particular process.
