Efficiency evaluation of three fluidised aerobic bioreactor based sewage treatment plants in Kashmir Valley Dilafroza Jan*, Ashok K. Pandit and Azra N. Kamili Centre of Research for Development, University of Kashmir, Srinagar-190006, Jammu and Kashmir, India. Accepted 5 April, 2013
The present investigation was conducted to monitor the physico-chemical characteristics and microbial load of sewage treatment plants (STPs) around the Dal Lake. The results show highly significant (P chemical oxygen demand (COD) > conductivity and fecal coliform (FC) > total coliform (TCC) > fecal streptococcus (FS) in the case of physico-chemical parameters and microbial characteristics, respectively. The overall performance of the wastewater treatment plant effectively removed TCC, FC and FS as follows, 52, 65 and 45%, respectively. Raw sewage showed insignificant (p>0.05) variation in some of the physico-chemical features and microbial load between the three STPs. Similarly, effluent also showed insignificant (p>0.05) variation in some of the physico-chemical features and microbial load, except conductivity which showed significant difference between the three STPs. Efficiency rates showed significant (p
