Abstract:

The primary objective of this project is to characterize the contamination to help decide the level of treatability that will be required in the removal of the contaminants. From this information, a determination was made about what types of wastewater pretreatment technologies are available to meet the required discharge limits NPDES or POTW for hydroblasting operations on a hull surface at a shipyard dry dock facility. The objective to this project was to identify the most practical and cost-effective methods to filter or treat runoff water from hydroblasting to meet Federal and State water quality requirements or local Public Owned Treatment Works POTW standards.
