Chemical treatment systems can remove suspended solids, emulsified oils and heavy metals
Coagulation/flocculation water treatment technology is typically
applied to remove suspended particles and/or emulsified oils
from water.
Coagulation
The purpose of coagulation is to neutralize the repelling charges
and to allow the matter to gather (agglomerate). For most wash
water and industrial wastewater applications, coagulation can
be accomplished by mixing a chemical coagulant (a cationic
positive charged chemical) into the water, or by applying
Electro-coagulation (an electrolytic process using an electrolytic
sacrificial cell and DC current) to the water.
