Product DescriptionQDEVU® Cavitation Air Flotation(CAF)
Water Treatment Plant DescriptionQCAF series Cavitation Air
Flotation Machine(CAF) is a new type of solid-liquid
separation equipment specially designed for removing grease,
colloidal substances and solid suspended solids from industrial and
municipal sewage. For different wastewater, by adding
appropriate flocculant and coagulant aid, COD and BOD can be
removed more than 30% to 80% in this pretreatment stage (the use of
agents and removal efficiency need to be determined by
experiments). The removal rate of oil and suspended
matter is more than 80%-95%. Adding decolorizing agent and
dephosphorizing agent can effectively remove chroma and phosphate
ion. QDAF air float adopts negative pressure suction,
low energy consumption, low operating cost, 0.1KW-0.5KW/H water
consumption, linear bending of impeller aperture, gas section
diffusion, not easy to plug, high working efficiency, simple
operation and maintenance. Working principle CAF is through
the high-speed rotation of the impeller, the negative pressure
layer is generated in the aeration area, the air is transmitted to
the impeller through the central pipe, with the high-speed rotation
of the impeller released to the negative pressure layer and sewage
mixing, the high-speed rotation of the impeller will repeatedly cut
the bubbles into small bubbles. In the process of
floating in the dissolved air tank, the small bubbles are mixed
with the sewage that has been flocculated, and the large particles
float to the surface of the water. The scum is pushed to the slag
removal tank by the slag scraper and discharged to the sludge tank.
ApplicationPetrochemical, paint, leather, paper, slaughter,
textile, printing and dyeing, dairy products, palm oil, soybean
oil, machinery processing and other industries waste water. Can
also be used as paper mill fiber recovery equipment, printing batik
process section rosin recovery equipment. Features1. No air
compressor, no circulating pump, low energy consumption. 2.
High processing efficiency and small footprint. 3. Low
failure rate of aeration system, easy maintenance. 4. Large
aperture of impeller, not easy to plug. Product
