Polymers for Water Treatment
Flocculation is a process by which, with the addition of substances called flocculants, the colloidal substances present in the water are agglutinated, facilitating their decantation and subsequent filtering.
It is a step of the process of purification of waters of superficial origin and of the treatment of sewage domestic and industrial.
The compounds that it treats are the solids in suspension, the colloidal particles and the dissolved substances.
The flocculation process is preceded by coagulation, which is why we usually talk about the coagulation-flocculation processes.
These facilitate the removal of suspended substances and colloidal particles, and avoid the use of disinfectants.
The use of polymers improves water treatment through its ability to trap contaminants very effectively.
