  • Ballasted Flocculation Water Online

    With ballasted flocculation, screened sewage is combined with a coagulanttypically ferric chloride or alumin a flash mix tank, where the microsand and polymer are added. The microsand provides a large number of particles (contact area), enhancing the flocculation rate, and acts as ballast to accelerate the settling of the floc.
