FIELD: separation.
SUBSTANCE: invention generally relates to processes of removing deposition substances from membrane surfaces and, in particular, from membranes for direct osmosis. System for solution dewatering includes membrane made with possibility of partial enclosing with initial solution and receiving of through flow of drawing solution; and a device configured to control the flow of said drawing solution through said membrane; wherein said system is configured to operate in three different preset operating modes, including filtration mode, osmotic relaxation mode and pulsation mode; wherein said membrane comprises a membrane structure.
EFFECT: higher efficiency of the membrane and elimination of its blocking.
