FIELD: process engineering.
SUBSTANCE: proposed method comprises the following stages: collecting rinsing water in receiver suitable to this end, processing said water by one or more water-soluble polymer. Note here that said water-soluble polymers are selected from the group including amphoteric polymers, cationic polymers wherein specified load density varies from about 5 mol % to about 100 mol %, zwitter-ion polymers and combinations thereof. Said water-soluble polymers may be mixed with said rinsing water to be forced through membrane. Said membrane represents ultrafiltration or microfiltration membrane.
EFFECT: possible back-flushing of membrane to remove dry substance from membrane surface.
