Part of the reflux gas pressurized dissolved air flotation is one of the types of gas pressurized dissolved air flotation.
Working principle of the traditional gas pressurized dissolved air flotation, rely on the water pump will bullishness of floating part of treated water backflow pressure into the dissolving tank, at the same time, through the pressure of the air compressor or water ejector or pressure pump suction on the suction pipe to the air pressure into dissolved air, under the condition of constant pressure air into the water, and then through the release of dissolved air water pressure returned to normal pressure, will release a large number of tiny air bubbles and flocculated grain of adhesion in raw water, and make the flocculant has been removed.
But used this kind of air flotation system users will encounter dissolved air water is not stable, and remove the effect of unstable phenomenon, the main reason is that the reflux water too much (detergent) with air in the dissolving tank XingBuCheng dissolved air water, but only seen in the dissolving tank sight glass bubble, sometimes dissolving tank pressure up to 0.4 Mpa, and dissolved air water release is not a big bubble, is the tiny water droplets, sometimes looks milky dissolved air water, and the bubble is detergent, never even purification purposes.
And JHDF type high efficiency air flotation, the introduction of Germany import new technology, the suction with the reflux water through the pump inlet gas, then through the pump impeller pay cut into tiny dissolved air water, through the relief valve to release into the milky dissolved air water, make the flocculation floatation, purification so as to achieve purpose.
This gas floating won't because of the reflux water too much detergent XingBuCheng dissolved air water consequences, but also overcome the general gas floating reflux dissolved air pressure pump, the disadvantage of low dissolved air rate, this is a new type of high efficient, trusted user optional air flotation.
