Dissolved Air Flotation an overview ScienceDirect Topics
In dissolved air flotation (DAF), bubbles are produced when the dissolution of air in water occurs under very high pressure. In this method, bubbles diameter typically ranges between 10 and 100 μm ( Chen et al., 2011; Naghdi and Schenk, 2016 ). Some of the factors that influence the efficiency of this technique include bubbles size
Flotation efficiency of activated sludge flocs using
The activated sludge process is one of the most frequently used processes for biological wastewater treatment. Conventional gravity sedimentation (CGS), which is widely used as a secondary clarifier in activated sludge processes, has a routine problem due to floating tendency, called bulking, caused by filamentous microorganisms.
