Microalgal system for treatment of effluent from poultry litter anaerobic digestion

► Poultry litter anaerobic digestion effluent (PLDE) diluted into water at 6% (v/v) supported significant algae growth. ► Multiple dosage of PLDE recoded better algae growth relative to single dose. ► Algae biomass productivity of 76 mg L−1 d−1 was recorded under booster dosage conditions. ► Average biochemical composition of dry biomass (w/w) was; protein 39%, carbohydrates 22% and lipids 10%. ► Algae removed 60% of total nitrogen and 80% of total phosphorus present in PLDE.
