Abstract
The rapid development of restaurant services has resulted in the generation of restaurant wastewater also increasing. The liquid waste contains pollutants BOD, COD, TSS, Total-N, PO4, and oils and greases with high enough levels so that they can pollute the environment if they are transferred to river bodies without prior processing. This study aims to determine the optimal HRT, optimal aeration rate, and optimal GAC mass to reduce parameters in restaurant wastewater by applying short HRT to the operation of the reactor. In this study, an experiment was carried out by applying granular activated carbon - sequencing batch reactor processing to treat restaurant liquid waste. In this study the reactor was operated with short HRT of 6, 9, and 12 hours and compared with a comparison HRT of 36 hours. In the reaction phase, a GAC mass of 0.4 and 2.5 grams was added. The highest removal was BOD of 91.23%, COD of 93.35%, TSS of 98.94%, PO476.60 %, Total-N of 89.78%, and oils and greases of 99.99% . Based on this study, it can be concluded that the optimal HRT for reducing BOD and COD is 12 hours, the optimal HRT for reducing TSS and oils and greases is 6 hours, and the optimal HRT for reducing PO4 and Total-N parameters is 36 hours. GAC was affixed during the reaction phase with a mass variation of 0.4 grams and 2.5 grams, the optimal GAC mass was obtained at a GAC mass of 0.4 grams. The aeration rate was operated at a rate of 20 L/min and 40 L/min, the optimal aeration rate was obtained at a rate of 20 L/min. Keywords: Restaurant wastewater, sequencing batch reactor, hydraulic retention time, granular activated carbon, aeration rate.
