The diagram below shows a basic water treatment process for surface water.
Diagram drinking water treatment process.
Drinking water sources are subject to contamination and require.
Quality of raw water.
Text in this example.
Slow sand filtration is essentially a biological process whereas rapid sand filtration is a physical treatment process.
This article throws light upon the four processes of waste water treatment.
Choice of water treatment process choice of treatment process depends on choice of treatment process depends on.
Screening water is passed through coarse screens where large fl oating debris twigs plastic bags etc are removed.
However even in the u s drinking water sources can become contaminated causing sickness and disease from waterborne germs such as cryptosporidium e.
Water treatment is any process that improves the quality of water to make it appropriate for a specific end use.
The end use may be drinking industrial water supply irrigation river flow maintenance water recreation or many other uses including being safely returned to the environment water treatment removes contaminants and undesirable components or reduces their concentration so that.
Drinking water supplies in the united states are among the safest in the world.
Many water treatment plants use a combination of coagulation sedimentation filtration and disinfection to provide clean safe drinking water to the public.
The four processes are.
Flocculation clarification tank lake reservoir or river coagulation filtration.
As already stated preliminary treatment involves the removal of floating materials leaves papers rags and settleable inorganic solids.
Drinking water treatment sedimentation the heavy particles floc settle to the bottom and the clear water moves to filtration.
The water is then passed through fi ne screens which remove much of the algal content.
Surface water is more often treated rigorously than underground water as it has less contaminants.
1 preliminary treatment 2 primary treatment 3 secondary or biological treatment and 4 tertiary or advanced treatment.
Coli hepatitis a giardia intestinalis and other pathogens.
The water then flows through pipes to homes and businesses in the community.
Drinking water treatment plant process animation.
Worldwide a combination of coagulation sedimentation and filtration is the most widely applied water treatment technology and has been used since the early 20th century.
Many small private water supplies will rely on cartridge filters consisting of a woven or spun filter within a standard housing.
Concept of the treatment process.
Storage water is placed in a closed tank or reservoir for disinfection to take place.
The water passes into large settling tanks where solids are allowed to settle.
Suspended particles get stuck to the chemicals to form floc.
