Purposes of filtration

Unpasteurized beer is becoming more and more popular, but its production requires changes in the filtration scheme.

The generally accepted filtration scheme for the production of pasteurized beer is as follows:


This scheme does not guarantee the product sterility. Even with sterilizing cardboard, sterility is guaranteed at the outlet of the filter only. When the product passes through the bright beer tank and pipelines to the filling line (bottling), secondary insemination occurs.
NPP Technofilter recommends using an additional filtration stage – final filtration before filling. Final filtration allows you to retain particles and bacteria, thereby significantly increasing the shelf life of beer.

Proposed scheme:


or a scheme with replacing the filter presses with a cartridge trap filter:


Recommendations for filter cartridges

Filter cartridges for filtration before bottling of unpasteurized beer

Cartridge filter EPV.S is designed for high-quality filtration with the possibility of multiple flushing and regeneration.

EPV.S –is a death corrugated filter cartridge based on microfiberglass material with a large surface area and low resistance to flow. The filtration efficiency (practically at the membrane filtration stage) is achieved by the high adsorption capacity of the glass fiber as well as increased filter capacity.



High efficiency of bacteria and particle removal (98-99,5%)

  • Micron ratings 0.2 and 0.5 microns are available

Large surface area (pleated)

  • Higher flow rates with the smaller differential pressure

Stable matrix, reinforced construction

  • Reliable preservation of the integrity of the filter in harsh operating conditions
  •  The structure of the filter cartridge excludes "dusting"
  •  Withstands in-line steam sterilization, multiple backwash and all types of chemical sanitation
  •  Longer service life.

Operational characteristics

  • The maximum pressure drop - 0.5 MPa at 20 °C, 0.25 MPa at 90 °C 
  • Rinsing with hot water (at least 100 cycles) – 90 °C, 30 min 
  • Steam sterilization (at least 20 cycles) - up to 135 °C, 30 min
