Optimization Model for Wastewater Treatment Process

The Wastewater treatment plants play a vital role in supplying a stable source of water due to the fast population increase and increasing demand for clean and reliable water. Being able to dispose of or reuse wastewater safely is the main objective of wastewater treatment. However, before the wastewater is treated, the options for disposal or reuse must be examined so that the proper treatment technique may be applied. The water treatment system is made up of six subsystems that are connected in a series. The rates of failure and repair are considered to be exponentially distributed. The differential equations were developed using a probabilistic technique, and Markov; the birth-death approach, was used to create the mathematical model. These are then solved by the Runge-Kutta method. The findings could be useful to plant designers and those in charge of maintaining treated water quality.
