Complete mix flocculation process

摘要

A flocculation system for water treatment facilities comprises a flocculation tank having a plurality of baffles which divide the interior of the flocculation tank into a plurality of compartments. The baffles are arranged to provide intercompartmental openings between adjacent upstream and downstream compartments, which, in turn, are arranged to provide a serpentine flow path through the flocculation tank. A mechanical mixer is mounted in each compartment for supplementing the mixing energy provided by the serpentine flow, particularly during periods of low water flow rates.
