FIELD: process engineering.
SUBSTANCE: proposed device and filter are intended for water treatment. Device (1) comprises water flow rate controller (2). Note here that aid controller (2) comprises throttle (6) and leak-proof device (12) communicated with throttle (6) to interrupt the flow when pressure difference between throttle inlet and outlet is lower than preset magnitude. It includes water filter (34) and flow adder (28, 29) to add water flow downstream of water filter (34). Note also that water filter (34) communicates with throttle (6, 36) to constrict water flow rate through filter (34) at preset time interval.
EFFECT: decreased water flow rate.
