5. 1 What is the basic principle of flocculation and Coagulation ? TABLE OF CONTENTS 3 What is the purpose of flocculation in water treatment? 5 Factors affecting to coagulation - flocculation 2 The most commonly used inorganic chemical coagulants in water treatment? 4 The whole flocculation process is carried out in steps 6 How does flocculation system work? Drafting & CAD Technology Major for college

6. 1 Drafting & CAD Technology Major for college What is the Flocculation and Coagulation ?

7. Coagulation and flocculation are two separate processes, used in succession, to overcome the forces stabilising the suspended particles. While coagulation neutralises the charges on the particles, flocculation enables them to bind together, making them bigger, so that they can be more easily separated from the liquid.

11. 2 Drafting & CAD Technology Major for college What is the purpose of flocculation in water treatment?

12. Coagulation and flocculation remove a large number of organic compounds as well as suspended particles, including inorganic precipitates. The process removes particles and dissolved matter; however, the water may still contain pathogens, including viruses and bacteria. What is the purpose of flocculation in water treatment?
