WATER PURIFYING APPARATUS USING SEDIMENTATION AND DISSOLVED AIR FLOTATION

摘要

The present invention relates to a precise water purifying device using precipitation and floatation which purifies water by primarily precipitating flocks and secondarily lifting and removing the flocks after forming flocks in raw water. The present invention provides a precise water purifying device which utilizes an existing settling basin, and dissolved air flotation (DAF) is applied on the lower part of the settling basin; removes contaminants gathered by the settling basin via precipitation; removes contaminants of low specific gravity, algae, contaminants of low turbidity; and prevents a blockage of a sand filer basin caused by excessive algae. f the thermoelectric element while being in contact with the top surface of the thermoelectric element attached on the measurement object.
