Scenedesmus sp is a microalga that can be used to treat bodies of water with high levels of nutrients and organic matters. The objectives of this study are (1) to examine the effect of Potassium (K) and Carbon (C) addition on phosphate concentration. The study was conducted on a laboratory scale using a batch system and continuous aeration. Microalgae were cultured until chlorophyll-a concentration of about 3.5 mg/L was obtained. The phycoremediation process was carried out by adding the elements of K and C. The results of this study show that the reactor with the addition of 3% of K and 29.41 mg/L of C generated the lowest phosphate concentration of 1.40±0.01 mg/L. © EM International.
