What are ‘flocs

WebAeration in an activated sludge process is accomplished by pumping air into the tank or lagoon. Proper aeration promotes the growth of microorganisms or microbes in the wastewater. The microbes feed on the organic pollutants and form flocs which can easily settle out. The flocs are allowed to settle out in a separate settling tank or lagoon. http://pubs.sciepub.com/jaem/3/2/1/jaem-3-2-1.pdf chrysler sudbury

WebAs the primary treated wastewater enters the aeration tank, equivalent flow is displaced to the (secon dary) clarifier, carrying along the same concentration of MLSS as maintained in aeration tank.
