Water treatment is the process that removes contaminants and other harmful components to provide safe drinking water.
Most drinking water and water for industrial use or irrigation comes from water sources such as lakes, rivers, reservoirs, streams, wells, and the sea. Before it is fit for consumption, it must be treated to remove sediment and other organic materials that are harmful. Water used for irrigation or industrial use must also be addressed.
While there are many methods of treating water depending on the source and what it will be used for, most water treatment plants follow a fairly standard process. The exception to the rule is the treatment of seawater. Water with a heavy saline content goes through a desalination process.
The four steps are coagulation, sedimentation, filtration, and disinfection.
- Coagulation: Coagulants are added to the water at the inlet of the plant to help bind the sediment.
- Sedimentation: Water enters a sediment basin where the floc particles settle to the bottom, forming a sludge.
- Filtration: The water, clear of much of the sediment, goes through a filtration process. Sand filtration is often used here to catch the remaining deposits. Some plants will add filtration using activated carbon basins to remove bad tastes and odors from the water.
- Disinfection: The disinfection stage removes any remaining bacteria, viruses, and parasites. There are three main methods of disinfection, and they can be used individually or in combination—chlorine or chloramine treatments, UV radiation, and ozone treatment. Once the water has been disinfected, it enters the water delivery pipe network with its final destination being the tap.
