DEVICE TO PRODUCE SUPER PURE WATER BY REVERSE OSMOSIS Russian patent published in 2014 - IPC C02F1/44 B01D61/12 

FIELD: process engineering.

SUBSTANCE: invention relates to production of super pure water by reverse osmosis process. Proposed device comprises reverse osmosis filter module (6) divided by membrane (8) into primary chamber (7) and secondary chamber (9) and supply tank (3) with atmospheric vent including water feed pipe (1). Pipe (5) with built-in pump (4) extends from bottom end of supply tank (3) to primary chamber (7). Return concentrate pipe (14) extends from primary chamber (7) to supply pipe (3) while permeate pipe (28) extends from secondary chamber (9). Venturi pump (20) with converging chamber (21) and diverging chamber (22) is built in return pipe (14) and includes suction hose (18) to be selectively connected by plug joint (17, 26) with tank (27) containing disinfectant or with return concentrate pipe (14) upstream of Venturi pump 20. Plug joint (17, 26) comprises two plug-in connectors. The latter when disconnected make fixed part automatically close while connection or disconnection of suction hose (18) is registered and used as a control signal for reverse osmosis.

EFFECT: disinfection process can be notably automated.
