Bipolar Membranes

BIPOLAR MEMBRANES


The main components of electrodialysis modules are polymeric ion-exchange membranes. The Ion exchange membranes are nanoporous materials which functional  properties are determined by the properties of the thin surface layer with a thickness from several nanometers to micrometers.
At present JSC "Schekoniazot" launched production of high-quality membranes on the classical technology on domestic resins. The company is the only Russian producer of heterogeneous ion-exchange membranes marks MK-40, MA-40, MK-40L, MA-41I, MB-1, MB-2. Membranes suitable for use in electrodialysers and electrodialysis plants.

Bipolar membranes  brand MB-1, MB-2
• biolayer system consisting of a combined into one sheet cation and anion-exchange membranes.

The size of the standard membrane sheet is 1420*450 mm. Permitted, with agreement with the customer, manufacturing of membranes of other sizes, but not more than 1420*900 mm without changing their electrochemical and physicochemical properties. Operating temperature range of  membranes - 10-50 degrees of Celsius.

Membranes are used in installations for different areas:

• demineralization of whey;

• removal of citric acid from juice;

• purification of sugar syrups;

• desalting and deionization of water;

• wastewater treatment emitting valuable items;

• deep purification of biological and medical products;

• decontamination of radioactive wastewater;

• concentration of wastewater containing valuable components;

• preparation of water to heat.
