Abstract

Wastewater that been discharge from meat processing industry has high content of nutrients such as nitrogen and orthophosphate. These nutrients was found abundant in meat products which is essentials for algae growth specifically. However, if these wastewater being discharge to environment without any treatments to assimilate those nutrients, it can lead to eutropication which also known as algae bloom; resulting the destruction of the ecosystem and health to human. Hence, this paper will illustrate the superiority of using microalgae botryococcus sp. in assimilate nutrients from meat processing wastewater i.e. Total Nitrogen and Orthophosphates. Furthermore, through this study, the primary characteristics of wastewater to be established prior and after treatments for assimilation analysis. From this, the efficiency of microalgae in phycoremediation process can be ascertain and recognized. Three different concentrations of botrycoccus sp. were use i.e. 1x103 cells/ml, 1x104 cells/ml and 1x106 cells/ml. The microalgae then were cultivated into wastewater of 9.00 am and 12.00 pm. sampling in triplicate manner for phycoremediation took place. The results show that highest removal of Total Nitrogen and Orthophosphate is at concentration of 1x106cells/ml i.e. 97% and 94% at 12.00 pm. sampling. Same goes for Biological Oxygen Demand, BOD and Chemical Oxygen Demand, COD removal, maximum removal are also at concentration of 1x106 cells/ml i.e. 97% and 94% at 9.00 am. sampling.
