Abstract

In the present study, phycoremediation of the Guwahati Refinery effluent, Indian Oil’s first public sector refinery was studied using a pure culture of Tetradesmus dimorphus (Turpin) M. J. Wynne. Sampling was done at a monthly interval for a period of six months i.e., September, 2018 to March, 2019. Twelve physicochemical parameters of the refinery effluent were examined in the wastewater treated without test organism (T0) as well as in the wastewater treated with test organism (T1) at a sampling interval of 0 days, 10 days and 20 days. In every parameter being analysed, T1 showed better results than T0. The phycoremedial efficiency of T1 was recorded to be the highest on 20th day of incubation.
