Coagulation pretreatment techniques

Depending on the nature of the product, pretreatment of the feed material may be desirable to improve the separation characteristics. Possible techniques are based on chemical or physical treatment and include thickening, flocculation, and coagulation. A simple heat treatment process where the temperature of the broth is elevated and held for a period of time can reduce... 

A variety of treatment schemes serve as the most important and direct means of controlling the microbiological quality of drinking water. They involve storage, pretreatment, coagulation and flocculation, filtration, and disinfection techniques. They are usually used for source waters. Ground-waters often receive no treatment or only disinfection because of the low levels of contaminants.
