Drinking Water Treatment Process

Over time the now larger particles become heavy enough to settle to the bottom of a basin from which sediment is removed.

Drinking water treatment process. Drinking water treatment plants traditionally used oxidants at multiple points including early in the process to oxidize manganese and iron present in source waters allowing their removal in later precipitation steps and late in the process to kill microbial agents in the water. On this page you will find an explanation of a drinking water purification process. Water treatment is any process that improves the quality of water to make it appropriate for a specific end use. Pre sedimentation mixing flocculation settling filtration adsorption disinfection function of unit processes.

Although drinking water treatment practices vary most water treatment plants follow a six step process to remove undesirable contaminants. Drinking water supplies in the united states are among the safest in the world. This process causes small particles to stick to one another forming larger particles. There must be a method to get this water to the water treatment plant.

In addition to the globally increasing demand on drinking water other municipal and industrial processes are also dependent on efficient solutions for water supply and water treatment. Coli hepatitis a giardia intestinalis and other pathogens. 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. The constantly increasing demand on clean water and the water treatment associated with it is of global importance.

Drinking water sources are subject to contamination and require. All process steps are numbered and the numbers correspond with the numbers in the schematic representation of the drinking water process found below. The water treatment process generally adopted depends upon the quality of raw water and quality of water derived. However even in the u s drinking water sources can become contaminated causing sickness and disease from waterborne germs such as cryptosporidium e.

Collection the source water for a municipal surface water treatment plant is typically a local river lake or reservoir. Quite often a series of pumps and pipelines transport the water to the treatment plant. The first step in the treatment process is the removal of harsh grit particles sand gravel cinder etc and other large objects cans bottles tree limbs etc. The water treatment process includes many operations like screening aeration and sedimentation sedimentation with coagulation softening filtration disinfection etc.

Solids removal removal of ions and solids using chemical addition removal of smaller particles removal of. Pumps for wastewater treatment.
