Why is secondary treatment of water in sewage treatment plant called biological treatment

Answered By: Alex Bailey Date: created: Feb 10 2022

When BOD of sewage or waste water is reduced, the effluent is then passed into Settling tank where the bacteria flocs allowed to sediment. Secondary treatment of the sewage is also called Biological treatment because in secondary treatment biological factors/organisms play a major role in the treatment.

Why is secondary treatment necessary

Answered By: Lucas Williams Date: created: Jul 02 2021

A minimum level of secondary treatment is usually required in the United States and other developed countries. When more than 85 percent of total solids and BOD must be removed,… Secondary treatment removes the soluble organic matter that escapes primary treatment. It also removes more of the suspended solids.

What is primary treatment and secondary treatment

Answered By: Sebastian Watson Date: created: Oct 21 2021

Primary treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to secondary treatment.
