Abstract
This study was design to investigate the wastewater characteristic of the textile mill effluent. Various samples were collected at regular interval for a period 0f6-7 weeks and were tested for various wastewater quality parameters. It was observed that the wastewater generated by the textile mill is highly polluted in terms of releasing a high strength effluent. The mean average values COD, BOD, TSS and TDS observed was 9000mg/L, 6850mg/L, 1890mg/L and 2378mg/L, respectively. The effluent is slightly acidic in nature, with a pH of less than 6.10, and has objectionable odor and smell. Moreover, a moderate temperature, i.e., 21oC, at the point of its disposal into the receiving streams was noticed. The effluent was observed to have very critical DO concentration, i.e., 6.0mg/L. That can adversely effects entire water ecosystem, having such high organic pollutant strength. The results of this study suggest an end pipe treatment of the final effluent prior to its disposal in the receiving streams. The proposed, wastewater treatment plant suggested by this study consists of medium screens chamber, PST operating at SLR of 2.50ft3/ft2-hr, and the UASB reactor with diameter of 9.5m. The biogas yield capacity of the UASBR was estimated to be 1920m3/day.
