ChemREADY answers the question: What is Coagulation and Flocculation?

ChemREADY Explains What Is Digital Water Treatment? | GetChemREADY

Flocculation and Coagulation in water treatment are used to remove suspended solids through a process that destabilizes the suspended particles in water solutions. The difference between the two is coagulation is the coming together, or clumping of particles, and flocculation is the settling of coagulated particles.

Their purpose is to remove and neutralize charge density of particles with coagulation and then facilitate particle bounding through flocculation so that the larger aggregated particles easily separate from the water and settle to the bottle.

Common applications include:

Slurry Pond Management
Wastewater solids dewatering
Effluent wastewater treatment
Recycled plastics wash water treatment
Mining wastewater treatment
