RECOVERY OF SULFURIC AND PHOSPHORIC ACIDS FROM PROCESS WATER BY ELECTRODIALYSIS

RECOVERY OF SULFURIC AND PHOSPHORIC ACIDS FROM PROCESS WATER BY ELECTRODIALYSIS
PI: Tom Davis
Sponsor: FLORIDA INDUSTRIAL AND PHOSPHATE RESEARCH INSTITUTE
Center for Inland Desalination Systems (CIDS)
Amount awarded: $25,000

The ultimate goal of the research is to utilize the process water as a resource, rather than regard it a waste that requires harsh treatment so that it can be discarded. The best technique for removal of acid from a dilute solution is electrodialysis (ED) with special membranes. The PI has conducted laboratory ED experiments to recover sulfuric and phosphoric acids separately and found that these acids could be concentrated to about 2 molar from very low initial concentrations, the strength required for dissolution of calcium phosphate.
