Discharge of nutrients (e.g. phosphorus and ammonia) to surface waters can cause eutrophication and the formation of toxic algal blooms, threatening human health and the environment. However, current phosphorus treatment technologies such as chemical precipitation and conventional biological systems can be costly and ineffective to reliably achieve impending effluent regulatory limits of <0.1 mg/L. The objective of this project is to develop a novel, cost-effective solution for consolidating the treatment of phosphorus and other nutrients in wastewater, and subsequently recovering phosphorus as a concentrated solution that can be converted to a valuable bioproduct. Potential end-users of the technology include wastewater treatment plants seeking to meet tertiary treatment standards on limited budgets. The core
innovation of this early-stage research is the development of novel biocatalysts comprising specialized microorganisms capable of rapidly and reversibly accumulating phosphorus from complex wastewaters. Unlike conventional biological systems, the proposed technology does not rely on the growth and wasting
of biomass, thereby enabling a less expensive, energy-efficient, and minimal sludge process. Preliminary results show the promise of proposed technology to treat nutrients more rapidly and to lower limits than conventional approaches, while simultaneously creating the opportunity for phosphorus recovery to offset
costs and help protect environmental quality.
