A typical treatment of wastewater procedure nowadays consists of nine separate phases.
Fremont, CA: To cater to the demands of a rising population, we must extract as much water as possible to protect this valuable resource. On the other hand, water must go through a thorough water treatment procedure before being considered acceptable for human consumption. Just as monitoring water quality has evolved, so has its treatment.
A typical treatment of wastewater procedure nowadays consists of nine separate phases. While not all of these stages may get followed at every water treatment facility in the world, they form the foundation of the industry. The following are the nine steps:
Collection
Water must first get gathered from lakes, rivers, and reservoirs before being treated. Then, although natural means (including rivers) may get employed, most water is carried from the source to the treatment facility via a sophisticated network of pumps and pipelines.
Screening
Screening the water is the first phase in the treatment process, and it removes bigger suspended things, including trash, plants, trees, animals, and other detritus. Then, as the name implies, a big metal screen is used to trap and eliminate them.
Chemical addition
Chemicals are used to enable tiny suspended matter particles to cluster together and produce "floc." Coagulants are the chemicals used to do this, and there are various products available.
Coagulation
To allow the flocs to develop, the coagulant must be blended at various speeds over a period of time after it has been introduced to the water (this part of the process is known as flocculation).
Sedimentation and clarity
Sedimentation and clarity are two terms that are used interchangeably. The water is then routed through a sedimentation basin once the flocs have formed. The floc particles can collect at the bottom of the basin and be transferred to a disposal pond.
Filtration
After the bigger particles have been removed from the water, they will then be filtered thru a wide range of media, including sand, gravel, or activated carbon, to eliminate excess tiny undesirable particles.
