Bioextractive aquaculture as an alternative nutrient management strategy for water resource recovery facilities.

Advanced nutrient removal in water resource recovery facilities (WRRFs) can reduce coastal eutrophication, but can increase economic costs and indirect environmental impacts associated with energy and materials usage for WRRF construction and operation. A strategy of interest to reduce coastal eutrophication is the cultivation of seaweeds in proximity to WRRF discharge plumes to bioextract nutrients from coastal waters. We report economic and environmental trade-offs of this proposed strategy for a 1,170 m·d (0.
