dissolved air flotation, it is also called circular dissolved air flotation or high efficiency shallow air flotation.
DAF clarifier purify wastewater by removing suspended solids, is a cost-effective alternative to conventional sedimentation clarification process, specially designed for high TSS wastewater, oily wastewater, paper mills backwater as well effluents from sugar, dairy, food, textile industries and tanneries.
Compared to conventional sedimentation clarification process, DAF clarifier is:
*** Much more cost effective;
*** Lower engineering design costs;
*** Lower installation cost;
*** Shorter process time (require HRT only 3 - 5 minutes).
Features:
*** Short HRT, only need 3-5 minutes.
*** High surface load, 8-12m3/m2·h
*** Small disturbance to water, ensure stable performance.
*** Compact in structure with small footprint, suits for large capacity water treatment.
