Public water systems often use a series of water treatment steps that include coagulation, flocculation, sedimentation, filtration, and disinfection.
What Are the Water Treatment Processes for Runoff?
There are many water treatment processes for runoff, but the most common and effective ones are coagulation and flocculation, sedimentation, filtration, and disinfection.
Coagulation and flocculation involve adding chemicals to the water to bind together the small particles that make up runoff. This makes it easier for the larger particles to settle out of the water.
Sedimentation is the process of allowing the larger particles to settle out of the water. This can be done in a tank or basin, where the water is allowed to stand for a period of time.
Filtration is the process of passing the water through a filter to remove the particles that have been suspended in it. Disinfection is the process of adding a chemical to the water to kill any bacteria or other organisms that may be present.
These are the most common water treatment processes for runoff, but there are other methods that can be used as well. Some of these other methods include adsorption, ion exchange, and reverse osmosis.
