Nutrient removal and microalgal biomass production from different anaerobic digestion effluents with Chlorella species.

ABSTRACT: Potential of microalgal cultivation as an alternative approach to the treatment of anaerobic digestion (AD) effluents was examined using two representative Chlorella species, Chlorella vulgaris (CV) and Chlorella protothecoides (CP). Both species effectively removed NH₄⁺-N from the AD effluents from four digesters treating different wastes under different operating conditions. In all experimental cultures on the AD effluents, NH₄⁺-N (initial concentration, 40 mg/L) was completely removed within 10 days without residual NO₃^--N or NO₂^--N in batch mode. Compared to CP, CV showed greater biomass and lipid yields (advantageous for biodiesel production), regardless of the media used. Prolonged nitrogen starva
