Flocculation is a slow stirring process that causes the small coagulated particles to form floc. Water Teratment Process Water Treatment Process 5152018 11.

Drinking water treatment process. During drinking water treatment filtration is the most widely used process. Worldwide a combination of coagulation sedimentation and filtration is the most widely. The flocculation process promotes contact between the floc particles and the particulates sediment in the water.
Raw water intake flash mix coagulation flocculation sedimentation filtering disinfection distribution Natural and Man-Made Hazards Disasters and Risks Affecting Water Supply. Filter process may be either slow or rapid and operated by gravity or the water can be forced through the medium under pressure. Storage Water is placed in a closed tank or reservoir for disinfection to take place.
Drinking Water Treatment Sedimentation The heavy particles floc settle to the bottom and the clear water moves to filtration. -------f The most commonly used processes include filtration flocculation and sedimentation and disinfection for surface water. There are four main mechanisms for coagulation.
In general the process consists of many units as settling coagulation flocculation sedimentation filtration and disinfection. Aeration chamber Softening unit Filtration with chlorination Disinfection Function of unit processes. The water then flows through pipes to homes and businesses in the community.
Treatment Source Water Contaminants. These individual processes may be arranged in a treatment train a series of processes applied in sequence. First process in drinking water treatment coagulation is to destabilize the particles and allow them the potential to collide and stick together.
Aeration water treatment is effective for management of dissolved gases such as radon carbon dioxide some taste and odor problems such as methane and hydrogen sulfide as well as volatile organic compounds like MTBE or industrial solvents. Tap Water Surface water or groundwater 10. Drinking Water Treatment Aeration.
Water filtration is done through a porous bed of inert medium usually silica or quartz sand. It is also effective in precipitating. Gas removal cations and solids removal solids removal microbial removal Lime soda ash and chlorine.
The coagulated water then flows to the next major unit process the flocculation process. Water suppliers use a variety of treatment processes to remove contaminants from drinking water. Double layer compression adsorption and charge neutralization sweep flocculation and inter-particle bridging.
Many water treatment plants use a combination of coagulation sedimentation filtration and disinfection to provide clean safe drinking water to the public. In the drinking water treatment processes the optimization of the treatment is an issue of particular concern. Particles clay silt Natural organic matter Microcontaminants eg pharmaceuticals Bacteria Protozoa.
Drinking water treatment processes. The optimization of the process consists of some measures to decrease the managing and monitoring expenses and improve the quality of the produced water. Sweep flocculation is the primary.
