Optimal Design for Conventional Wastewater Treatment Systems using a Computing Language MATLAB R2012a

Abstract

In the present scenario of rapid urbanization, the demand for wastewater treatment is continuously increasing. The majority of research in the field of wastewater treatment plant (WWTP) is focusing on its modeling part. The design of WWTP is developed using professional quality software packages which incorporate the fundamental concepts with the key engineering principles. With the aim to obtain an optimal design, in this study a novel Decision Support System (DSS) is developed for the preliminary units integrating screening chamber, grit chamber and equalization tank with primary sedimentation tank as the primary process and activated sludge process, trickling filter and rotating biological contactor as different types of the secondary units of Wastewater Treatment System using a computing language MATLAB R2012a. DSS is a comprehensive and user-friendly program which could incorporate most of the theoretical and practical constraints. One of the major concerns of DSS is the dimension constraint for the design and operation of WWTP. DSS incorporates miscellaneous mathematical functions and the code to develop a user-desired design. The applicability of the DSS model is illustrated through the various design problems. The design developed will support the future growth and development of the cost optimization models for WWTP.
