Abstract

Microalgae have the ability to remove nutrients such as nitrogen and phosphorus and reduction of COD, BOD and increasing levels of DO in effluent samples. This study evaluated the performance of algae on nutrient removal from wastewater treatment. Percentage reduction of 87,85,87 and 84% of BOD, COD, TN and TP respectively was observed in the experimental group, where as compared to controlled experiment, it was observed after two weeks since the start of batch reaction, the percentage removal was observed for as 67,57,35 and 22% of BOD, COD, TN and TP. Microalgae increased DO from 0.87 ppm for raw DO while experimental group showed 4.69 ppm and controlled experiment showed 1.80 ppm.it was observed the final BOD remained in the effluent was within NEMA standards, as for COD didn’t meet NEMA standards. However, the wastewater sample that was collected had nutrients well below the required standards but still the microalgae improved the sample by attaining 87 and 84% removal for TN and TP. Consequentially, the study concluded that microalgae have dual benefits of removing nutrients, reducing BOD and COD and increasing the DO.
