Dissolved Air Flotation(DAF)

Dissolved Air Flotation(DAF)

Dissolved Air Flotation (DAF) is a clarification process for the separation of solids, grease and oils. Dissolved Air Flotation works by producing a stream of micro-fine air bubbles that attach to solids and float them to the surface where they can be removed by a surface scraping mechanism.

It can be used in the following industires such as paper making, textiles, dyes and pigments, leather making, electroplating, oil refining, chemical, rubber, meat processing, canned food wastewater treatment and other sewage treatment.

l          Fiber recycling of paper making industry can be up to 95%~98%.COD removal 80~95%.All treatment water can be recycled and used again.

l          Wastewater treatment in textile, dyes and pigments industry, turbidity removal, decolorization up to 70~90%, COD removal 60%~85%

l          Electroplating industry, the mixed wastewater contains various metal ion, after handling, Cr+6, Cu+3, Ni_1, Zn+2 removal rate above 90%, up to the effluent standard.

l          Leather making wastewater, suspension removal 90%, COD removal 70%

l          Chemical industry( paint, dyestuff) COD removal rate 70%, rubber wastewater COD removal 80%.

l          Fiber glass wastewater, oil refinery wastewater, (included in mineral and plants, after treatment, it can decrease below 10mg/L for low temperature, low turbidity wastewater purification,outflow can reduce minus 5 degree.
