What Is Coagulation and Flocculation in Wastewater Treatment?
Apr 03, 2018· The combination of coagulation and flocculation is particularly useful at exceeding these guidelines. Using these two treatment methods with sedimentation and filtration, assigned a removal credit for Giardia, will leave only inactivation.

Treating the Public Water Supply
In flocculation, small particles with nonrigid surfaces are made to agglomerate by mixing the water (and thus bringing the particles into contact with one another so that the surfaces can become stuck together). When the agglomeration of the particles gets large enough, the aggregate can settle in still water by sedimentation.

Flocculation is stimulation by mechanical means to agglomerate destabilized particles into compact, fast settleable particles (or flocs). The objective is to bring the particles into contact so that they will collide, stick together, and grow to a size that will readily settle. The flocculation process relies on turbulence to

Settling column tests were conducted to investigate the sedimentation behaviour of untreated and fly ashbased geopolymer stabilised dredged mud slurries. Standard onedimensional consolidation (Oedometer) tests were used to evaluate the compressibility and consolidation characteristics of the untreated and the fly ashbased geopolymer stabilised dredged mud sediments.

Application Data: Coagulation and Flocculation
Flocculation is the binding or physical enmeshment of these destabilized particles, and results in a slime that is heavier than water, which settles out in a clarifier. Flocculation agents are natural synthetic polymers and synthetic organic polymers used to form the flocculant (Figure 1 demonstrates the flocculation process in the
