Microalgae based wastewater treatment and biodiesel production is gaining attention in recent years. Present
research study highlights the phycoremediation potential of Scenedesmus obliquus for removal of contaminants present in
CETP treated effluent. CETP treated effluent was collected from kalol Gandhinagar and was characterized for various
physicochemical parameters i.e. nitrate, phosphate, pH, EC, TDS, BOD, COD, Chloride, ammonia etc. Scenedesmus
obliquus showed nutrient removal efficiency i.e. 46.1% TDS, 52% Nitrate, 21.5% Phosphorous, 45% BOD, 40.1% COD,
42.8% ammonia, 10.3 % Chloride respectively. The algal strain characterized indicates presence of maximum lipid
productivity 6.43±0.77 mgl-1

; Lipid content 27.4±1.46 % and biomass productivity 23.48±3.5 mgl-1
d
-1 at the end of the
experiment. The result obtained from the research study showed effective nutrient removal from wastewater and the biomass
obtained can also be used as a source for biodiesel production.
