摘要：
Optimal water management is an essential prerequisite for sustainable development in Egypt. The reuse of wastewater could be an effective providence for unrestricted irrigation. The novel route in wastewater treatment using microalgae minimizes the harmful impact of wastewater on the environment and produces sustainable products. An economic assessment of this case study is performed. The average removal for the chemical oxygen demand (COD), the biological oxygen demand (BOD), and the total suspended solids (TSS) respectively is 41 %, 49 %, and 56 %. The feasibility study of a large-scale system revealed that this system is promising with a return on investment percent (ROI) of 97.3 %. The total consumed energy for a large scale is 0.02 KW.h/m3ww. While the annual CO2 consumption is 647.75 T, and annual oxygen production is 470.412 T. This study is paving the route towards a sustainable zero-waste process.
