Flocculation is the process of agglomerating destabilized particles into bigger flocs. In wastewater flocculation and sludge treatment, colloidal particles are flocked in order to aid their removal or to help sludge dewatering. Polymers can be used alone or together with inorganic coagulants to make flocs bigger and more resistant to shear forces.Web
