Final filtration of wine

Membrane filtration is the most common method for achieving microbiological stabilization of beverages without using chemicals or heating. As an alternative to pasteurization, cold stabilization preserves the aroma, flavor and fine structure of the wine.

Membrane filters such as EPM provide absolute retention of microorganisms that cause damage to the wine. Filters of fine purification of the EPV type, which have a high mud capacity and resource, provide excellent protection of the membrane element and increase its working life.

Features and applications

Necessary conditions for perfect final filtration of wine:

  • Careful preliminary preparation of wine material. 
  • Pre-filtration of wine through a filter press with high-quality filter board. 
  • Availability of sterile service media. 
  • Prepared storage tanks equipped with filters for sterile breathing. 
  • Thorough sterilization of equipment and all materials in contact with wine. 
  • High level of sanitary-hygienic state of production facilities.


We present the new generation cartridge filter based on polyethersulfone membrane EPM.PS, specially created for the biological filtration of wine with the possibility of multiple washing, regeneration and sterilization.

Characteristics Advantages for Customer
The filter is based on a reliable pleated polyethersulfone membrane with excellent performance characteristics.
  • Wide chemical compatibility (pH 1-14)
  • Excellent thermal resistance (up to 100°C in water).
  • Low ability to bind proteins.
  • Longer service life due to an increased surface area up to 0.76 m / 250 mm.
High efficiency of retention bacteria and microorganisms (99.98%).
  • Available with pore sizes of 0.65, 0.45 and 0.2 microns. Guaranteed removal of yeast cells, molds and pathogenic bacteria before bottling.
Pronounced asymmetric pore structure and an increased total porosity of the membrane.
  • High filtering speed and small differential pressure reduce financial costs.
Reinforced construction, longer service life.
  • Reliable preservation of filter’s integrity under harsh operation conditions.
  • The possibility of multiple sterilization ensures economical operation.
100% control for quality assurance, integrity testing.
  • Microbiological reliability means that the breakthrough of delayed particles and microorganisms is excluded.
  • Guarantee the integrity and effective operation of the product. Can be checked by a special integrity test during operation.
Non-toxic, pyrogen-free.
  • Passed extensive tests and certified for use in the food industry, manufactured in accordance with a certified Quality Management System ISO 9001:2015.


  • Maximum operating temperature is 90° C at 0.20 MPa
