100T/D Carbon steel Dissolved air floatation machine for waste
water filtration system
Dissolved air flotation machine is suitable for the treatment of
small and mediium-sized industrial wastewater and urban
comprehensive sewage.It is used to remove suspended solids,grease
and various colloids in sewage.It can also recycle useful
substances.Dissolved air flotation can effectively remove SS,and
CODcr.
Working Principle
Pollutants in sewage can be divided into soluble organic matter and
insoluble substance (SS). Under certain conditions, soluble organic
matter can be transformed into non-soluble substance. One of the
methods of sewage treatment is to add coagulants and flocculants so
that most of the soluble organic matter can be transferred into
insoluble substance. Then all or most of the non-solution soluble
substances (SS) are removed to achieve the purpose of sewage
purification, and the main method of SS removal is to use the
method of air flotation. After the dosing reaction, the sewage
enters the mixing zone of the air float and mixes with the
dissolved air water after release. The air dissolved in the water
is released from the water and forms 20-40um tiny bubbles, which
makes the flocculant adhere to the tiny bubbles and then enters the
air float zone. Under the action of air buoyancy, the flocs float
to the water surface and form scum. After the lower level of clean
water flows to the clear pool through the water collector, part of
the water flows back to be used as dissolved gas, and the rest of
the clean water flows out through the overflow port. After the scum
on the surface of the air float tank accumulates to a certain
thickness, the scum is scraped into the air float sludge tank by
the scraper and discharged.
