B -- REMOVAL OF DISSOLVED COPPER AND ZINC, AND MARINE FOULING FROM WASTEWATER STREAM OF SHIP HULL CLEANING DEBRIS DUE 072296 POC Margaret Cox-Marvel, Contract Specialist, (215) 897-7164. The Carderock Division of the Naval Surface Warfare Center is seeking souces for processing equipment and technical expertise for the removal of: particulate cupros oxide and zinc oxide, dissolved copper and zinc, and marine fouling from a wastewater stream of ship hull cleaning debris. During in-water ship hull cleaning operations, barnacles, marine fouling, slime and other marine organic materials are removed from underwater hull surfaces which have been painted with an anti-fouling (AF) paint system. Design options are being developed to capture and evacuate this hull cleaning debris in seawater at a flow rate of up to 200 GPM. A nominal 4-inch diameter hose will convey the 200 GPM wastewater stream to a processing unit on the surface. The wastewater stream must be processed so that as little as 1 part per billion of dissolved copper or zinc are present in the seawater effluent. This announcement is to consider all potential sources to accomplish this task, but does not obligate the Government to award a contract. Requests may be faxed to (215) 897-7766. No telephonic requests will be accepted. (0172)
