Dissolved Air Flotation Introduction Suspended air flotation has been widely used in sewage treatment in recent years, and it can reasonably remove frivolous flocs that cannot be deposited in sewage. Dissolved air flotation (DAF) is suitable for low turbidity, high saturation, high organic compound content, low oil content, low surface active chemical content or algae-rich sewage. Compared with other air flotation methods, it has the advantages of high hydropower load and compact regulation tank. Characteristics聽 1. The聽suspended air flotation has large working ability, high efficiency and less floor space. 2. The whole process of the processing technology and the structure of the machine and equipment are simple, which is convenient for application and maintenance. 3. The effluent water body is good, not only low turbidity and low SS content, but also high dissolved oxygen. 4. The moisture content of the discharged scum is less than that of the sludge discharged from the grit chamber, which brings great convenience to sludge treatment and saves the cost of sludge disposal.Dissolved Air Flotation website:http://www.bioetp.net/dissolved-air-flotation/
