FIELD: process engineering.
SUBSTANCE: invention can be used in water supply systems for water purification to required standards. Proposed filter comprises transparent housing 1, chambers for initial and purified fluid 5 and 4, respectively, granular medium with indicator particles 2 and laminar grated drainage-distribution system 3 arranged there below, tubes to feed initial 6 and rinsing 10 fluids, filtrate discharge tubes 11 and waste fluid discharge tubes with valves an accessories. Ejector 16 with diffuser 17 and structuring tube 14, fast-operation valve, and vacuum-tank 20 arranged on suction pipe are connected to pure water chamber 4 via gate valve 15. Fast-operation valve inlet is connected to rinsing water tube and valve outlet is connected to ejector. Coarser grains of filter medium acts as indicator particles.
EFFECT: higher reliability, water quality and filter efficiency, simplified medium composition.
