The objective of this work was to evaluate the effect of different flocculating agents o Chlorella vulgaris (Beyerinck) biomass. The experimental design was completely randomized, consisting of three treatments and three replications each by the different flocculant agents totaling three treatments and three replications (0.5 M). The microalgae of C. vulgaris was conditioned in an erlermeyer with a useful volume of 2000 mL, reaching on the seventh day the exponential phase of its growth curve, initiating flocculation. The pH variation data were interpreted by analysis of variance, followed by Tukey test (P <0.05). There was a difference (P <0.05) in all treatments, but the use of sodium hydroxide as a flocculating agent obtained better result by rapidly increasing the pH of the culture (11.00 ± 0.37) and providing greater weight of dry biomass (0.1360 ± 0.0036 g / L).
