Optimal Wastewater Treatment Design by Using Genetic Algorithm

Abstract

Integrated advanced wastewater treatment provides important fundamental
solutions to problems associated with water scarcity prevailing in arid and semiarid
climatic
regions.
This was accomplished through treated water with specific specification
and characteristics suitable to be used for agricultural, domestic, and industrial
purposes. This study is concerned with the use of genetic algorithm procedure
for the optimum design of integrated advance wastewater treatment units, with
their various types and characteristics. The aim of optimum wastewater
treatment units design is to attain optimum values of certain pre-defined
objective function.
The objective function is to satisfy certain constraints and achieve minimum
capital, maintenance, and operation costs. Chemical clarification treatment unit
was used in this study.
This study includes development of computer program for advances
wastewater treatment plants design adopting genetic algorithm. The program
was developed using Matlab software.
The results obtained from this study include the finding of optimum design
criteria for advanced wastewater treatment plants. The obtained design criteria
are satisfying the required water quality with minimum treatment cost.
