KINERJA SEQUENCING BATCH REACTOR (SBR) AEROB PADA DEGRADASI GLUKOSA DENGAN VARIASI RASIO WAKTU PENGISIAN TERHADAP WAKTU REAKSI

Abstract

An aerobic sequencing batch reactor (SBR) was used to investigate the optimum organic concentration and the ratio of fill – react time. The synthetic wastewater used had approximately COD of 10,000 mg/l; 8000 mg/l; 4000 mg/l; and 2000 mg/l, in the room temperature between 23 – 26 °C. The ratio of fill – react time was (2:2) hours, (2:4) hours, and (2:8) hours.  The results showed that the optimum COD reduction of 70.62% was achieved in the influent concentration of approx. 4000 mg/l COD with the fill-react ratio of (2:2) hours.
