Effect of Temperature Variation on the Biological Treatment of Greywater in The Sequencing Batch Reactor

A sequential batch reactor was used in this study to treat greywater and to study the effects of temperature changes on the biological treatment process. samples were collected from several homes in Mosul. Changing temperatures from 10 to 36 ° C in order to optimize treatment, and three operational cycles of 6, 8, and 12 hours were used to get the optimal condition. The laboratory model is made more realistic by adding an air pump, and an electric temperature. Based on tests conducted for both the chemical oxygen demand (COD) and the total high solids (TSS), PH, and Nitrate (NO ₃ ), the best temperature for treatment was 36°C and 12 cycles. The efficiency of removing the COD was 89%.
