| Wastewater treatment is essential for protecting the environment and human health because it removes hazardous pollutants. In line with Egypt's Vision 2030, this study proposes a new approach to the design of distributed wastewater treatment networks, to reduce pollution discharge into the environment. The two main parts of the proposed strategy are as follows: first, treatment units are prioritized for implementation by giving lower flow rate units priority; second, the pinch method is employed to identify which streams should be treated in each unit. In the three case studies, the maximum allowable environmental limit concentration was set at 10 ppm, and the removal ratio for the treatment plants (TP) was set at 99%. The results show that, in case study one, the flow rates of TP1, TP2, and TP3 are 39.53 t/h, 38.89 t/h and 37.22, respectively. In case study two, the flow rates of TP1, TP2, TP3, TP4, TP5, and TP6 are 56.32 t/h, 54.64 t/h, 55.15 t/h, 55.55 t/h, 56.81 t/h, and 26.64 t/h, respectively. In case study three, the flow rates of TP1, TP2, TP3, TP4, TP5, and are 323.11 t/h, 107.10 t/h, 328.67 t/h,308.50t/h, and 248.57 t/h respectively. Based on these results, the discharge of contaminants into the environment at a concentration of 10 ppm was achieved. | ||
