DAF is designed to mainly remove fats, oils and grease (FOG), suspended solids (TSS), parts of biological oxygen demand (BOD) and chemical oxygen dem and (COD) that hard to be dissolved in water and other pollutants from waste water. The process is simple - tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water - but designing a DAF system for a real-world application isn't quite as simple.
Oil content in outlet water can be reduced less than 1mg/L
Broken ring, broken chain, decolorization, deodorant, disinfection
No man need on duty
The skid mounted structure is available out-of-the-box
No polymer consumption, low cost of investment and operating
An efficient performance of solid and liquid seperation,whicn is from unique dissolved air and micro bubble manufacturing technology.
