Coagulation is a wastewater & water treatment process that utilizes chemicals to remove unwanted substances such as suspended solids, and other applications that include thickening, water clarification, lime softening, and deposit dewatering.

Coagulation is very useful in assisting water filters in removing tiny pieces of particles that have a tendency to evade filtration. Coagulant chemicals work in producing positive charges to neutralize the negative charges on the particles. This process effectively combines small particles into larger ones that are easier for water filters remove.
