Aquatic pollution is a man-made phenomenon, arising either by increasing the concentrations of naturally occurring substances or by adding non-natural synthetic compounds (Xenobiotics etc.) to the environment. Tannery effluents are marked as top prioritized pollutants among all the industrial wastes. Phycoremediation is an eco-friendly technique in which microalgae used as a bio-tool to treat the effluents without adding any chemical additives that enhanced the pH and DO and reduces the nutrients concentration. In the present study, the tannery effluent water samples were collected from tannery industry situated at Erode, Tamil Nadu, India to study the role of microalgae in tannery effluent water treatment. The tannery effluent water was treated with cultured strains of Chlorella sp (JM13) and Scenedesmus sp (JM10) for 15 days. Samples were periodically (every after 3rd day) analyzed for Physico-chemical parameters such as pH, phosphate, nitrate, BOD and COD using standard methods. The strain JM13 showed the best removal capacity of nitrate and COD while JM10 showed BOD and phosphate reduction up to 2 weeks. The combination of JM13 & JM10 reduces the COD and BOD at 88% and 89% respectively while nitrate and phosphate were reduced drastically at the rate of 90% and 97% respectively. The present investigation focuses on the phycoremediation of tannery effluent water using microalgae as safer, less expensive and more efficient approach to remove nutrients and metals. The output of this treatment may be filtered and converted as biofertilizer for agricultural practices.
