Title: Resource Enhancement and Recovery of Domestic Wastewater Residuals

Deadline: 5/26/2021 2:00 PM   (UTC-05:00) Eastern Time (US & Canada)

Status: Deadline Expired

Solicitation Number: 36773

Description:

District ambient water quality monitoring data has indicated that watersheds with large biosolids applications have experienced off-site migration of nutrients and oxygen-demanding organic matter, thus accelerating the eutrophication of downstream waters.  To better define the extent of this problem, the Florida Department of Environmental Protection (FDEP) has provided funds to the St. Johns River Water Management District (SJRWMD) to undertake an investigation of the quality of surface waters in areas where biosolids and biosolids derivative products have been land-applied.

 

Despite the adverse consequence excessive phosphorus (P) loading, the disposal of wastewater residuals to agricultural or urban lands for fertilization and soil conditioning still represents its most reasonable and beneficial use and is preferable to the alternative of landfilling. Thus, a potential solution would be to reduce the amount of P in biosolids, bringing it into agronomic nutritional equivalency with nitrogen. The optimal solution should seek to conserve P, for sustained crop production, rather than immobilize P.

 

The objective of this work is to evaluate the efficacy of key technologies for reducing P load resulting from biosolids. The preferred technologies will recover P efficiently by forming a product that is valuable for sustainable application.
