A Low-Cost Chemical Remediation Technology for Chromium in Shipyard Stormwater

A novel remediation method to reduce environmental and human health risk from Cr(VI) in shipyard stormwater is in the process of being developed by SIROM Scientific Solutions. We have successfully pre-tested a low-cost, environment-friendly material to remove Cr(VI) from shipyard stormwater. We propose to use this novel material in an easily-depoyable fixed bed reactor to reduce the amount of Cr(VI) in shipyard stormwater. We propose to develop an easily-depoyable fixed bed reactor containing the proposed low-cost sorbent installed in shipyards to remove Cr(VI) from raw water before it is released into the sea. Phase I studies will include bench-scale experiments to demonstrate the efficiency of the packed bed reactor system to remove Cr(VI) from shipyard stormwater. Results from the Phase I study will demonstrate the potential use of a chemical Cr(VI) remediation system, assisting in US Navy efforts to comply with regional water quality standards of effluents discharged to marine environments at a minimum cost. The Phase-II study will scale up the bench-scale operation to a demonstration study, where the technology developed in Phase I will be tested under field conditions.
