TECHNOLOGY ASSESSMENT FOR REMOVAL OF TOTAL DISSOVED SOLIDS FROM SALTY WASHWATERS GENERATED FROM VEHICLE WASHING OPERATIONS
The purpose of this study was to identify a cost-effective technology for salt removal from washwater wastestreams at the Ontario Ministry of Transportation Patrol Yards. This document presents a detailed review of technologies for the removal of total dissolved solids from salty washwater. Technologies that are available to treat salty washwater wastestreams include evaporation, membrane processes and freezing. Atmospheric evaporation and electrodialysis were found to be the most appropriate technology for developing a liquid concentrate using the volumes and concentrations of washwater wastestreams generated by patrol yards using regional treatment facilities.
