Wastewater Treatment Plants

Product Details:

Wastewater treatment plants serve as a critical component of modern society, protecting the public from pollutants which may be present in sewage and effluent from industrial operations. The most widely used method of wastewater treatment is biological treatment using bacteria to break down organic wastes. Properly treated wastewater is returned to the environment for reuse.

A wastewater treatment plant generally consists of primary, secondary, and sometimes even tertiary treatment. For example, in most municipal sewage treatment plants the primary treatment consists of sedimentation tanks; the secondary treatment means microbiological decomposition or bio-decomposition. Further stages may include micro filtration, ultra filtration or nano filtration for removal of micro-organic particles or ion exchange for hardness or heavy metal ions or activated carbon for organic molecules.

In the wastewater treatment plant, water is treated in several stages. The first stage takes place at the settling tank, where water circulates to allow particles to settle out of it. The second stage takes place at an aeration tank, where oxygen levels are moderated and living organisms dine on the sewage. The final stage takes place in a clarifier, where remaining solid waste sinks to bottom and can be taken away. How effective is this process? It has been used for over 2,000 years, so we guess pretty effective!
