WATER TREATMENT APPARATUS AND METHOD Russian patent published in 2006 - IPC C02F1/20 B01D19/00 

FIELD: water treatment, in particular, degassing, purification and conditioning of water.

SUBSTANCE: apparatus has supply pipe, discharge pipe, locking-adjusting and measuring equipment, pump, tank, at least two contours equipped with interconnected supersonic liquid-gas ejectors mounted in upright position with upward oriented receiving chambers. Receiving chambers of ejectors are directly connected with each other through vapor-gas pipeline. First contour is designed for water to be treated and second contour is designed for circulating working fluid. Second contour has circulation pipe connected with circulating liquid tank equipped at its lower part with heat-exchanger. Method involves supplying water under pressure to nozzle unit of liquid-gas ejector so as to produce in ejector mixing chamber two-phase supersonic water mixture and gas and vapor released therefrom; simultaneously vacuumizing ejector receiving chamber through the use of second supersonic ejector positioned in parallel with first ejector in independent contour so as to cause circulation of working fluid in contour; discharging vapor-gas phase through vapor-gas pipeline which directly connects receiving chambers of ejector; supplying water to be treated to ejector under pressure enabling continuous flowing of supersonic two-phase mixture in mixing chamber of ejector during vacuumizing of its receiving chamber, with temperature of water under treatment process exceeding temperature of working fluid in contour of ejector adapted for vacuumizing.

EFFECT: increased efficiency in degassing of water, reduced consumption of power for operation of apparatus, and decreased material usage.
