The traditional processes of wastewaters have been used to eliminate settled and the organic material present in wastewater. Organic materials that were released into the environment lead to organic pollution. Microalgae cultures offer an elegant solution to the tertiary treatment of wastewater processes. The present study illustrated the role and efficiency of the blue-green algae and green algae in wastewater treatment. Hapalosiphon sp. and Scenedesmus spp. were cultivated on wastewater for 15 days for phycoremedation of wastewater and production biomass of algae, Hapalosiphon sp. removed 85.41% of BOD,84.16% of COD, pH was between 7.65-7.95, chlorophyll a reach highest growth 7.75 mg/l in nine days of the experiment, Scenedesmus spp. removed 60.41% of BOD,66.04% of COD, pH was between 7.62-7.92, chlorophyll a reach highest growth 3.84 mg/l in nine days of the experiment, this study shows that Hapalosiphon sp. is the most efficient algae for wastewater phycoremedation and higher biomass production.
