What is Flocculation?

How Flocculation Works Flocculation occurs when small particles in a solution lose their repelling forces and begin to attract one another. The small particles then bond together to form "flocs" or "flakes." Under most circumstances, a flocculant is necessary to begin the flocculation process.
