Abstract

Greywater is domestic wastewater from showers and sinks and has a significant potential for the protection of water resources as it is less polluted in terms of nutrients, inorganic substances and hazardous organic substances. It is aimed to treat and reuse greywater in order to meet the rapidly increasing water demand. In this research, the treatment of greywater using the Fenton Process was studied. The efficiency of the Fenton Process was optimized using the Box-Behnken Statistical Design Software. As a result of this study, 97.88 % of Chemical Oxygen Demand removal was achieved at pH = 3, Fe 2+ dose of 3 mM, H2O2 dose of 2 mM, and 37 min. The effect of Potassium Permanganate on the treatability of synthetic greywater was also investigated in the study. Results showed that 84% of the Chemical Oxygen Demand removal efficiency could be achieved using 0.1 g/L Potassium Permanganate at the end of 1 hour reaction time.
