Abstract
The present investigation was carried out to characterize and assess the treated paper mill effluent from the Seshasayee Papers and Boards (SPB) Pvt. Ltd., for physico-chemical and biological properties. Treated paper mill effluent samples were collected from SPB, Pallipalayam, Namakkal District of Tamil Nadu and were analyzed in the Department of Environmental Sciences, Tamil Nadu Agricultural University, Coimbatore. The paper mill effluent collected from SPB, Pallipalayam was light brown in colour. The effluent was found to be neutral in reaction with a pH of 7.87. It recorded an EC of 1.19 dS m-1. The effluent had considerable amount of cations like calcium (46.67 mg L-1), magnesium (19.6 mg L-1), sodium (101.70 mg L-1) and potassium (15.99 mg L-1) along with anions like chloride (127.03 mg L-1), bicarbonate (201.3 mg L-1) and sulphate (88.88 mg L-1), respectively. The BOD and COD values of treated effluent were 17 and 39 mg L-1, respectively. The paper mill effluent supported a considerable amount of microbial population.
