Wastewater resource recovery facilities that support urban populations are often landlocked and need to intensify their processes to meet more stringent effluent permits or increase their treatment capacity. Adoption of high productivity, small footprint (intensive) microalgal technologies creates an opportunity to sustainably convert waste nutrients to marketable products and meet rigorous effluent nutrient criteria. While EBPR may remove phosphorus to effluent concentrations approaching 0.1 mg-P•L -1 , the EcoRecover process has demonstrated long-term recovery of phosphorus to achieve effluent total phosphorus concentrations below 0.03 mg-P•L - 1 , even in winter months in Wisconsin (latitude of 45° N). An additional advantage of algal-based systems is the potential for organic phosphorus (and organic nitrogen) recovery, which remain a critical challenge for conventional bacterial and precipitation-based nutrient removal technologies. Future studies may specifically focus on organic nutrient recovery, as well as the sustainability implications (e.g., reduced chemical dosages and CO2 sequestration, increased process energy consumption) of replacing alternative tertiary treatment processes such as chemical phosphorus polishing.
