Modeling Assessment of Wastewater Treatment Plants for Sustainable Environment in Sudan: The Case Study Wd-Daffiaa Wastewater Treatment Plant (WWTP)

During past period, It was realized that the factors of the location characteristics of treatment plants and treatment system’s outlets had significantly effect on the environmental sustainability; Location characteristics of treatment plants and treatment system’s outlets assumed to have significant effect. Therefore, minimizing of environmental impacts is become one of the main functions of wastewater treatment systems. They should be designed in such away so that their total impact on the environment is reduced. Khartoum is a growing Mega city in a developing country, which is facing rising pressures on water-treatment environmental provisions due to the rapid population growth, and urbanization, and resultant governance and infrastructural issues.This paper discusses the issue of environmental sustainability represented in treating the wastewater of the few sewage plants in Khartoum that face critical problems, while taking WD-DAFFIAA TREATMENT PLANT as a case study. The study focused mainly on how to achieve the environmental sustainability in DAFFIAA wastewater treatment plant, and it aimed to provide elements of environmental sustainability by developing a systematic method (computerized model) for its evaluation. Based on sub criteria, a comparative analysis of criteria was used to create a modeling assessment of the environmental sustainability of wastewater treatment plant using: Super Decision Software (SDS) & programming languages. This method showed the different characteristics that affect wastewater of treatment plants in Khartoum.
