FLOAT COMBINE FOR WASTE WATER PURIFICATION Russian patent published in 2018 - IPC C02F1/24 B03D1/14 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to waste water purification. Waste water treatment float combine includes body 1, on the outside of which there are nozzles for supplying source water 3, tapping of purified water 7 and withdrawal of float sludge 14, a block for thickening the flotation sludge in the form of ejector 11 and a joint sludge dewatering unit and a flotation sludge using bag 16 of synthetic fabric. Inside the body perforated element 13, branch pipe for supplying working fluid, semi-submergible partition 6 with a lower window with a grid are installed. Synthetic fabric bag 16 is disposed on vibrating platform 18 with filtrate outlet 20 which is connected by conduit 21 to working fluid supply pipe 2 on the combine body. Pump 22, coagulant feed nozzle 23, a pair of magnets 24, flocculant supply branch 25, air conditioning chamber 26 are sequentially mounted on the pipeline. Distance between the nozzles of coagulant supply 23 and flocculant 25 is from 10 to 500 diameters of pipeline 21.

EFFECT: invention makes it possible to increase the efficiency of waste water purification and to increase the degree of sludge and float sludge dewatering.
