Description:

Ultra high water jetting can be used to remove coatings as an alternative to dry abrasive blasting. There are several advantages, including no requirements for a TNRCC air permit. The TNRCC and Advisory Council (www.advisorycouncil.org) are working in partnership to encourage water jetting for the appropriate application. The TNRCC has sponsored technical workshops on this technology.

P2 Application:

Water jetting eliminates air contaminants and waste abrasive materials that must be disposed of.

Environmental Benefits:

This technology can effectively remove different types of coatings from ships. The water resulting from the operation can be collected and sent to the local POTW or treated to remove any hazardous constituents. Water jetting can significantly reduce the costs associated with the disposal of spent dry abrasive materials.

Additional Information :

The pay-back for this technology is something to consider in converting to water jetting. From a life-cycle perspective, the technology can eliminate regulatory issues, permitting, and other environmental costs that make it attractive. It can also reduce the potential for worker exposure to dry abrasives.
