Following coagulation, flocculation, a gentle mixing stage, increases the particle size from submicroscopic microfloc to visible suspended particles.

A coagulation-flocculation process, based on aluminium sulfate, is studied in this paper using Response Surface Methodology, in order to establish the optimum parameters to achieve a maximum suspensions removal. This repulsion prevents the particles from agglomerating, causing them to remain in suspension.
