Abstract
Although a number of optimization models have been developed for the least‐cost design of wastewater‐treatment systems, very few models are available for water‐treatment systems. The present study proposes a method toward optimal design of water‐treatment systems, considering integration of process optimization in system optimization; particle‐size distribution (PSD) for process design and selection; relatively general simulation models; membrane processes in the alternative evaluation; sludge treatment/handling processes; multicriteria for alternative evaluation; and algorithms for process and system optimization. The paper is divided into two parts. The first part presents the important features of simulation models along with the simulation results and the second part highlights the optimization models and algorithms used for the optimal design. Results from the simulation study indicate the importance of influent particle‐size distribution on the performance of flocculation, sedimentation, and filtration processes. Recycling of the sludge sidestreams from gravity/centrifugal separation processes to the head of the water‐treatment plant and the filtrate disposal into sewers are economically and environmentally justified.
