  QCL-SDAF is the best tool for treating suspended solids, chroma, and total phosphorus in sewage! It represents a brand-new dissolved air flotation technology, with various characteristics exceeding traditional dissolved air flotation.
   The sewage and high-pressure air containing flocculants pass through a single or multiple heterogeneous mixing devices to directly complete the pressurized dissolved gas process in the wastewater, and the formed flocs are "solid-liquid-gas" dispersed mixtures under high pressure.
   Once the pressure is reduced, the dissolved air in the floc slowly releases and grows, squeezing out the water in the floc. While the moisture content of the floc is significantly reduced, its own specific gravity becomes lighter and lighter, and it floats on its own without external force.




Advantage
Covers an area as small as 1/3 of traditional air floatation
The removal rate of insoluble pollutants (COD, SS, chroma, etc.) is over 95%
Ultra-high speed stirring makes the reaction time of sewage medicament fast and the dosage of medicament is small
