Abstract

PURPOSE: To remove effectively the colloidal organic substances sticking to the membrane, by contacting the membrane with enzymatic agent or enzyme-containing detergent after the pressure on the membrane has been released and the membrane has been taken out for a definite period of time, at the removal of contaminants which have sticked to the memgrane surface at the treatment of the solution containing (in)organic substances with the permeable membrane.
