PLANT FOR DEFFERIZATION OF UNDERGROUND WATERS IN BED Russian patent published in 2001 - IPC

FIELD: water supply; applicable in piping of underground waters by hole water intakes. SUBSTANCE: plant has water supply wells with water hoisting devices and water conduit for each water supply well. Water conduit is connected with pressure pipeline by means of check and control valves. Installed on pipeline for water supply to well is aerator in the form of ejector with air chamber and mixing chamber. Head of each water supply well is sealed and provided with branch pipe connected with aerator air chamber. Internal surface of mixing chamber is made in the form of nozzle. Provided on internal surface of mixing chamber are crank helical grooves. Internal surface of ejector nozzle part has cycloid conductors spiral in form. Branch pipe of pipeline for water supply into well is connected by flexible pipeline brought to well strainer bottom. Settler has holes provided with nozzles widening toward bed. Nozzle internal surface is made in the form of curved spiral grooves. Rigidly secured to external surface of settler above nozzles are baffles. EFFECT: increased degree of deferrization of underground waters in bed due to full mixing of aerating air with water before its supply to well and within strain zone. 2 dwg
