FIELD: filtering engineering.
SUBSTANCE: member comprises perforated tube for discharging filtrate and diaphragm stacks applied on the tube via a turbulizing grid. The turbulizing grid has free access to the outer surface of the member, and the member is additionally rolled with the turbulizing grid. The diaphragm stacks are provided with semi-permeable diaphragm drain made of three layers of grid material. Two outer layers are load-bearing ones, and inner layer is discharging one. The member has reflecting collar that overlaps the free passage of the liquid to be filtered and roll member mounted at the face opposite to the face for supplying liquid to be filtered.
EFFECT: enhanced efficiency and reliability.
