Drinking Water Treatment Process

This is a summing up of the process steps.

Drinking water treatment process.

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. 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. Over time the now larger particles become heavy enough to settle to the bottom of a basin from which sediment is removed. Pre sedimentation mixing flocculation settling filtration adsorption disinfection function of unit processes.

The water treatment process includes many operations like screening aeration and sedimentation sedimentation with coagulation softening filtration disinfection etc. The water treatment process generally adopted depends upon the quality of raw water and quality of water derived. The constantly increasing demand on clean water and the water treatment associated with it is of global importance. Water treatment is any process that improves the quality of water to make it appropriate for a specific end use.

However even in the u s drinking water sources can become contaminated causing sickness and disease from waterborne germs such as cryptosporidium e. Treatment schematic sw potable drinking water sequence of unit processes. Sometimes as is the case of. This process causes small particles to stick to one another forming larger particles.

Drinking water supplies in the united states are among the safest in the world. Pumps for wastewater 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.

Solids removal removal of ions and solids using chemical addition removal of smaller particles removal of. There must be a method to get this water to the water treatment plant. All process steps are numbered and the numbers correspond with the numbers in the schematic representation of the drinking water process found below. Collection the source water for a municipal surface water treatment plant is typically a local river lake or reservoir.

On this page you will find an explanation of a drinking water purification 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.
