Comparing dissolved air flotation and conventional

Dissolved air flotation (DAF) is generally considered more effective than sedimentation (S) in the treatment of algal rich water. However, the type and dose of coagulant, as well as the coagulation (C), flocculation (F) and DAF operating conditions are key parameters for removing intact cyanobacterial cells.
