What is Coagulation in wastewater treatment? how can flocculants and coagulants help your business? How can they save you potential fines and help you stay compliant? Have a read of our article and get in touch with our team who will be happy to answer any questions.
Coagulation and flocculation describe the chemical process of contact and adhesion whereby the particles of a dispersion (colloids) form a larger-size cluster (flocs or flakes) allowing them to be more easily removed from water (e.g. by settling). The coagulation-flocculation processes facilitate the removal of suspended and colloidal particles. It’s used in the first stage of solids-liquids separation: settling, flotation or filtration.
In water treatment, coagulation-flocculation involves the addition of polymers that clump the small, destabilized particles together into larger aggregates so that they can be more easily separated from the water.
Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation process can be used as a preliminary or intermediary step between other water or wastewater treatment processes like filtration and sedimentation.
