AB This study evaluates the feasibility of removing nutrients by the microalgae Chlorella vulgaris, using urban wastewater as culture medium, namely the effluent subjected to secondary biological treatment in a wastewater treatment plant (WWTP). For this, laboratory experiments were performed in batch cultures to study the effect of initial nitrogen and phosphorus concentrations on growth and reduction of nutrient performance of C. vulgaris. The microalga was cultivated in enriched wastewater containing different phosphorus (1.3– 143.5 mg · L−1 P-PO3− 4), ammonium (5.8–226.8 mg · L−1 N–NH+ 4) and nitrate (1.5– 198.3 mg · L−1 N–NO− 3) concentrations. The nutrient removal and growth kinetics have been studied: maximum productivity of 0.95 g SS · L−1 · day−1, minimum yield factor for cells on substrate (Y) of 11.51 g cells · g nitrogen−1 and 0.04 g cells · g phosphorus−1 were observed. The results suggested that C. vulgaris has a high potential to reduce nutrients in secondary WWTP effluents.
