Microalgal growth in municipal wastewater treated in an anaerobic moving bed biofilm reactor

Abstract

Nutrient removal from the effluent of an anaerobic moving bed biofilm reactor (AnMBBR) treated with microalgae was evaluated. Algal treatment was highly efficient in removal of nutrients and discharge limits were met after 3 days. Extending the cultivation time from 3 to 5 days resulted in a large increase in biomass, from 233.3 +/- 49.3 to 530.0 +/- 72.1 mg L-1, despite nutrients in the water being exhausted after 3 days (ammonium 0.04 mg L-1, orthophosphate
