PLANT TO OFFTAKE AND CLEAN WATER FROM SURFACE SOURCES Russian patent published in 2012 - IPC E03B3/04 

FIELD: machine building.

SUBSTANCE: proposed plant comprises water intake, transition chamber with closed top and check valve arranged in top section, pump, compressor with air tube, air eliminators, electrically driven gates, control unit, at least two electrophoresis chambers closed from top, and submerged electrically drive pump. Water intake comprises flotation tank closed from above with perforated tubular air distribution system and outlet side holes made at its bottom. Jet apparatus submerged in source water is arranged on air tube. The latter communicates with pressure tank. Pressure tank is located at water intake bottom. Every electrophoresis chamber is equipped with electrodes arranged at top and bottom and air eliminators arranged at top. Every chamber is equipped with electromagnetic check valves fitted at top, bottom and center of water intake chamber. Submerged electrically driven pump is arranged in water intake chamber to communicate with water lift tube. Inclined protective canopy is installed on vertical part of aforesaid tube above water intake. Water flow rate pickup is arranged on horizontal section of water lift tube. Water flow rate pickup is connected with control unit. Control unit is connected with electrically driven gates on air lift and air tubes, pressure pickup, transducer of electrophoretic mobility of suspension particles, pump, compressor, all check valves and DC source. Pressure pickup is mounted on air tube. DC source is connected with electrodes.

EFFECT: higher quality of water cleaning, expanded performances.
