INORGANIC MATERIAL MEMBRANE AND METHOD OF ITS APPLICATION Russian patent published in 2008 - IPC B01D71/02 B01D61/42 

FIELD: mechanics; filtration.

SUBSTANCE: invention relates to the field of production and application of membrane filters made from inorganic materials and may be used in various industrial branches for purifying and concentrating solutions, processing waste waters, purifying potable water and service water, etc. The membrane has a ceramic substrate and a conducting membrane layer. The latter is a carbon selective layer produced by applying a polymer-graphite mix onto the ceramic substrate with subsequent drying and furnacing with no oxygen in the 600 to 1400 °C temperature range. The solution is forced through the membrane obtained and between the electrodes. The conducting membrane layer makes one of the electrodes. The proposed invention allows increasing the separation efficiency along with power savings in the process of separation.

EFFECT: increase in separation selectivity along with power savings in the process of separation.
