STP design calculation for 100 KLD SBR (Sequential batch reactor)

Abstract

Sewage treatment aims to remove the contaminants from different municipal sources in order to prevent pollution of aquatic bodies. There are numerous sewage treatment systems available in the market, including ASP (Activated Sludge Process), MBBR (Moving Bed Bioreactor), MBR (Membrane Bioreactor), etc. One of them, the SBR (Sequential Batch Reactor), is a remarkable technology that may be used in large-scale treatment plants due to its simple maintenance. Sequential batch reactors (SBR) are reactors or basins in which the biological treatment of waste water is carried out in a series of four steps, namely filling, aeration, settling (clarification) and decanting. One of the newest solutions for treating municipal sewage is the sequential batch reactor (SBR). In this research designing study, a thorough design computation for a sewage treatment system with a 100 KLD capacity was elucidated. In this study, two important aspects of design calculation such as units available in the SBR scheme and Equipment’s available in the SBR scheme. Thus, the simple calculation makes it easier for any design engineers to construct their sewage treatment plant or system.
