The present study illustrates the efficiency of microalgae based treatment system. Microalgae can treat the wastewater very efficiently (that contain organic components in abundance. The paper emphasize on the practical aspect of biological removal process that is natural in which Microalgae removes substances (both organic and inorganic), BOD, COD and other impurities present in the wastewater in the presence of sunlight and CO2. During the study it was found that variability in algae play a different role in treatment process. It has been observed that nutrients removal efficiency of microalgae is very high and effective as it removes 78-99% of Nitrogen and Phosphorus. The treatment system also succeeds to remove 40-65% of COD, BOD and other impurities present in wastewater. This paper reveal that the bioremediation capacity of microalgae to treat wastewater would be a better alternatives to the classic wastewater treatment process. This study focused on the sorption capacity of two algal species Chlorella vulgaris and Hydrodictyon reticulatum in four different places (1.Civil line, Chaupati,. B.T. Ganj and.
