Investigation on optimization of conventional drinking water treatment plant

Abstract

Conventional drinking water treatment plant consists of coagulation, flocculation, sedimentation, and filtration and disinfection units. Depending on water quality influent, each unit can be optimized to achieve the desired water quality effluent, both in design and operation stages. A typical water treatment plant has the combination of processes needed to treat the contaminants in the source water treated by the facility. The presence of unbeatable organic or mineral substances causes some problems in obtaining drinking water. Understanding these phenomena requires taking into account the physical and chemical natures of the water to be treated. Optimization of conventional drinking water treatment plant means “to attain the most efficient or effective use” of your water treatment plant regarding some principles, there are: achievement of consistently high quality finished water on a continuous basis and the importance to focus on overall plant performance, instead of focusing too much on individual processes. This paper presents a review on optimization of conventional drinking water treatment plant that eventually proposing a method to maximize process efficiency with less risks. Overall optimization was carried out by dynamic programming to meet drinking water quality standard.
