Abstract
India is the largest producer of sugar and generates 0.16 – 0.76 m 3 of wastewater for every ton of crushed cane. In this paper, the effect of pH and seed sludge on simultaneous treatment and ethanol production from a sugar mill wastewater using anaerobic sludge was investigated. The sugar mill wastewater had following composition: pH (6.69 ±0.45 ), reducing sug ar (5 – 6.83 m g/mL), chemical oxygen demand (5000 – 8 000 mg/L), total nitrogen ( 22.73 – 22.97 mg/L), and NPOC (1589 – 1647 mg/L). Seed sludge (10 –
50 % v/v) and pH (4
5.5) were varied in this study. Organic
carbon removal was determined by analyzing non
purgeable organic carbon (NPOC) in a TOC liquid analyzer. Fermentation process was carried out for 24, 48, 72, 96 and 120 h. Maximum ethanol yield of 0.00133 L/L of sugarcane wastewater was obtained at pH of 5.5 using 10 % v/v seed sludge. Moreover, 46 % NPOC removal was achieved under this condition. India produces 900000 m 3 of sugarcane wastewater annually. According to the present study, it is possible to produce 11 84 m 3 of ethanol per year from sugarcane wastewater by treating the wastewater in anaerob ic reactor under an acidic condition. However, detailed pilot study is required to determine the economic and technical feasibility.
