and accordingly will see improvements in treatment such as: Humic and fulvic molecules separate better with lower pH. Humic and fulvic acids are organic acids commonly found in raw water sources; Less coagulant is required for treatment; Flocculation improves at a lower pH 2012-06-15 · Coagulation–flocculation and factors determining floc evolution. Coagulation–Flocculation in general is a two phase process aimed at removing stable particles by forming larger aggregates that can be separated from the aqueous phase by a subsequent separation step.

Coagulation means to curdle; it basically refers to a chemical process in which the destabilization of non-settleable particles takes place. These particles form clumps with the help of a coagulant. On the other hand, flocculation means to form flocs.

About coagulation and flocculation. Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.
