Abstract

Abstract- Microalgae grown on wastewater are a probable source of low cost wastewater treatment and biodiesel production. In the study, microalgae was enumerated and identified as Chlorella sorokiniana by 18S rDNA sequence which was cultivated in different wastewater for nutrient removal as well as biodiesel production were studied. The results reveal that the pH of different wastewater samples almost neutralized by microalgae, the total dissolved solids elimination ranging from 52 to 66%, the biological oxygen demand removal efficiency varied much among different wastewaters the removal rate is of 72 to 90%, the chemical oxygen demand removal ranges from 59 to 75%. The magnesium level was decreased and efficiency is about 36 to 60%, the sulphates absorption efficiency was ranging from 57 to 68% and the chloride removal efficiency was 13 to 33%. The lipid content was obtained from the algal biomass which are grown in different wastewater samples was transesterified for biodiesel production, the biodiesel was analyzed by FTIR which meets the ASTM and EU standards, hence from the current study it is evident that Chlorella sorokiniana can be effectively used for potential source for phycoremediation and biodiesel production
