A Study on Optimum Design Periods of Wastewater Treatment System

Abstract

An initial task for the designer of wastewater treatment works is the selection of a time period for which the works are intended to serve. Selection of this deign period establishes the boundary conditions i.e. population to be served, quantity of waste water to be treated, degree of treatment required, funds required to finance the project, and the revenues to be generated. This makes it to proceed in the usual manner with the design of particular unit treatment process. In this chapter an attempt has been made to present briefly research overview regarding the concept of stage design period as suggested by the different research workers over the past three decades. Some local wastewater treatment plants data were also collected and evaluated with a review to meet the objective of the study.
