Safe Drinking Water is Essential - Coagulation-Flocculation

Coagulation-Flocculation. Coagulation and flocculation practices are essential pretreatments for many water purification systems.. In conventional coagulation-flocculation-sedimentation, a coagulant is added to the source water to create an attraction among the suspended particles. The mixture is slowly stirred to induce particles to clump together into “flocs.”

In modern water treatment, coagulation and flocculation are still essential components of the overall suite of treatment processes – understandably, because since 1989 the regulatory limit in the US for treated water turbidity has progressively reduced from 1.0 NTU in 1989 to 0.3 NTU today.

Flocculation - Aquatec Maxcon

Flocculation is the agglomeration of small particles and colloids to form larger settleable or filterable particles (floc), for removal in subsequent treatment processes. Flocculation begins immediately following particle destabilisation in the preceding coagulation stage. Often, flocculation aid polymers are used to assist in forming denser floc particles.
