See our User Agreement and Privacy Policy. Coagulation and flocculation are two processes commonly used in water treatment in order to get rid of unwanted suspended material in water. These heavy dirt particles are called flocs. •The mixture is slowly stirred to induce particles to clump together into “flocs.” •The water is then moved into a quiet sedimentation … Actions. In flocculation one can make a distinction between … 1. It involves the reduction of surface charges responsible for particle repulsions. After coagulation the destabilized particles can collide, aggregate so flocs can be formed. Sedimentation Flocculation Coagulation Coagulation and Flocculation Coagulation and flocculationconsist of adding a floc-forming chemical reagent to a water to enmesh or combine with nonsettleable colloidal solids and slow-settling suspended solids to produce a rapid-settling floc. Dirt particles in the water then stick together or coagulate and continue to stick together until heavy particles are formed. Clipping is a handy way to collect important slides you want to go back to later. If you continue browsing the site, you agree to the use of cookies on this website.

Coagulation: Coagulation is the step where colloidal par ticles (similar t o spheres of a diameter of less than 1 micrometer) are destabilized. Get the plugin now. Overview of coagulation and flocculation 1 1.1. Large, heavy particles settle out readily, but smaller and lighter particles settle very slowly or in some cases do not settle at all. Topics of Discussion • The place of flocculation within a water treatment process • The use of coagulation and flocculation in the water industry • Softening • Separation of flocs by settling and flotation 04/27/16 water treatment 35 36. coagulation, the coagulant chemicals neutralize the electrical charges of the fine particles in the water, allowing the particles to come closer together and form large clumps. 5/3/2012 PPTs online, safely and virus-free! Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Effective agents: Mineral colloids and polyelectrolytes. Chemical additives like sodium hydroxide and sodium hexametaphosphate (SHMP) may be added to water to reduce corrosion. Because of this, the sedimentation step is usually preceded by a chemical process known as coagulation. Looks like you’ve clipped this slide to already.
