What Is A Sewage Treatment Plant

Sewage Treatment Plant treats all wastewater by removing contaminants from the sewage. This leads to the discharge of treated water into the environment. The treated water can be used for irrigation, car washing, or other such activities that do not require potable water. Sewage is a collection of wastewater from businesses, households and industries. The objectives of sewage treatment plants are to prevent water pollution and promote water conservation.

Sewage Treatment: A Multiple-Choice Answer
There are plenty of sewage treatment processes to choose from. For example, there can be an onsite sewage treatment plant for buildings, societies and office parks or a combined treatment plant where sewage from significant territories like cities and states is treated together.

There are both natural and mechanical ways to treat sewage. A sewage treatment plant essentially pumps oxygen into the sewage to break down the contaminants by promoting the growth of pollutant eating bacteria. Sewage treatment aims to turn sewage into reusable or dischargeable water that will not pollute the environment.

Usually, in sewage treatment, water is first kept in a chamber until particles like oil, solid wastes and grease float up at the top, and the remaining solid wastes settle down in the chamber. After this water enters the second chamber where oxygen is pumped to help pollutant eating bacteria grow as these bacteria turn major pollutants into microscopic particles. Water is kept under observation in the last stage until the remaining impurities are settled down at the bottom. After that, the treated water is discharged and used for activities that do not require fresh water.
