Dissolved air flotation thickener

for sludge treatment

The residual activated sludge of a 98- 99.8% moisture content, micro bubbles and reagents are mixed in a flocculation reactor, which forms bubble flocs and then sends them through a mixing chamber, where they coagulate and grow larger. The sludge containing bubble flocs floats and gathers in sludge concentration zones and then separate from clean water using a buoyancy and sludge fence components. The moisture content in the sludge is gradually reduced, and the sludge gradually becomes dryer. Water extruded from the sludge is collected and discharged through a recycling water pipe in the middle of the pool body. Application Pretreatment of high concentration waste waters in slaughterhouses, printing and dying industries and stainless steel pickling water Sludge thickening treatment of municipal residual activated sludge
