      Flow equalization usually involves construction of large basins to collect and hold wastewater streams, from which the wastewater is pumped to treatment facilities at a constant rate. These basins usually are located after pretreatment facilities . Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial al, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment.A by-product of sewage treatment is a semi-solid waste or Application level: City, neighborhood.

Chemical neutralization is employed to balance the excess acidity or alkalinity in. Flow equalization is not a treatment process in itself, but a technique that can be used to improve the effectiveness of both secondary and advanced wastewater treatment processes.

The first step Author: Sasan Kordrostami. Handbook of Water and Wastewater Treatment Plant Operations, the intent of the author is twofold. The Þrst intent is to consolidate the information and experience in waterworks and wastewater treatment plant operations that have evolved as a result of technological advances in the Þeld, and as a result of the concepts and policies.

The Biological Wastewater Treatment series is based on the book Biological Wastewater Treatment in Warm Climate Regions and on a highly acclaimed set of best selling textbooks.

This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment.

Flow equalization is the process of mitigating changes in flow rate through a portion of a system by providing storage to hold water when it is arriving too rapidly, and to supply additional water when it is arriving less rapidly than desired.

In many water treatment systems, it is useful to implement flow equalization downstream of the plant. U.S. Environmental Protection Agency, Evaluation of Flow Equalization in Municipal Wastewater Treatment, US EPA/, Cincinnati, OH, May ().

The most notable of these benefits are the following: 1. municipal wastewater is considered an environmentally sound wastewater disposal practice compared to its direct disposal to the surface or ground water bodies [3,8].
