Right now, centrate are recycled back for repeat treatment
which adds very significant load for the energy intensive
wastewater treatment process (Li et al., 2011). Therefore, using
centrate as a resource for algae cultivation could serve dual
purposes: improving wastewater treatment efficiency and algal
biomass production. Our previous studies have shown that this
nutrient-rich wastewater stream is the best among all municipal
wastewater streams for algal cultivation with high biomass
accumulation and high efficiency wastewater nutrient removal
