Difference Between Coagulation And Flocculation In Water Treatment

Coagulation and flocculation are used to separate the suspended solids portion from the water.

Difference between coagulation and flocculation in water treatment. Coagulation and flocculation. There are three steps. On the other hand flocculation means to form flocs. Thus we can understand the process of coagulation and flocculation with the help of examples derived from water treatment techniques.

However they can be commonly adopted for de stabilizing any suspension system. In modern water treatment coagulation and flocculation are still essential components of the overall suite of treatment processes understandably because since 1989 the regulatory limit in the us for treated water turbidity has progressively reduced from 1 0 ntu in 1989 to 0 3 ntu today. Suspended particles vary in source charge particle size shape and density. It can be described as a physical or a mechanical process in which the coagulated clumps or flocs are joined together to form.

Particles in water such as clay usually have a negative charge. It basically refers to a chemical process in which the destabilization of non settleable particles takes place. Correct application of coagulation and flocculation depends. These particles form clumps with the help of a coagulant.

There s a difference between coagulation and flocculation and the mechanism that causes particles to aggregate and come together so that they can be filtered or settled. Flocculation brings the de established colloidal particles together and they form large aggregates. Coagulation and flocculation are important processes in water treatment with coagulation to destabilize particles through chemical reaction between coagulant and colloids and flocculation to transport the destabilized particles that will cause collisions with floc. Key difference coagulation vs flocculation in water treatment water treatment is an important aspect which involves many different steps.

Groundwater and surface water contain both dissolved and suspended particles. Flocculation and coagulation treatment chemicals are used in effluent water treatment processes for solids removal water clarification lime softening sludge thickening and solids dewatering. Coagulation is the neutralization of the electronic charge on suspended particles. Main difference coagulation vs flocculation coagulation and flocculation are two processes commonly used in water treatment in order to get rid of unwanted suspended material in water.

Coagulants neutralize the negative electrical charge on particles which destabilizes the forces keeping colloids apart. Flocculation and coagulation treatment chemicals are used in effluent water treatment processes for solids removal water clarification lime softening sludge thickening and solids dewatering. Since water treatment is a very sensitive and important process it requires the presence of both physical and chemical processes.
