Abstract

The present research focuses on the treatment of grey water collected from different sources. The technology used gave a satisfactory performance by reducing BOD and COD of the effluent considerably to 69 and 98 mg/L, respectively. Dyes and metal concentration present in the water were also reduced considerably. The analysis of dye adsorption kinetics gives the best fit to the Freundlich isotherm (R2 = 0.978) and follows the pseudo-second-order kinetics. The technology is a combination of physicochemical treatments, packed bed media filtration, adsorption, and disinfection. The aim of the work is to recycle and reuse the treated effluent for washing, toilet flushing, etc. The developed process addresses goal 6, 11, and 17 of the sustainable development goals (SDG) 2030. It is expected to be an effective, economic, and attractive solution to collective urban residential buildings as well as individuals.
