Demonstration of a Centrifugal Separator and Ultra-Filtration Membrane System for the Treatment of Shipboard Bilgewater

WP-200902

Objective

The objectives of this project are to demonstrate the performance of a centrifugal separator and ultra-filtration (UF) membrane system for processing shipboard-generated oily waste, measure key effluent quality parameters, and validate the system's ability to meet discharge requirements. Additionally, the evaluation will determine system reliability, operation and maintenance requirements, and ship integration issues.

Technology Description

The 3-gallon per minute (gpm) Aircraft Appliances and Equipment Ltd (AAE)/CINC Industries combined oil water separator (OWS) system consists of a primary stage centrifugal separator with a secondary stage UF membrane polisher that is designed to meet Department of Defense (DoD) vessel requirements. The system has been selected for installation on the DDG-1000 Class being designed by Northrop Grumman Shipbuilding (NGSB). The individual components have been successfully tested; however, the combined system has not been tested to see if it will function as a complete unit and meet discharge and operational requirements. The compact and modular design of the system and the anticipated ability to process a broad range of influent oil concentrations show promise for shipboard use on existing and future vessels.

Benefits

Current parallel-plate OWS systems are not able to meet the 15-part per million (ppm) oil concentration discharge limitation effectively and reliably. The ability to meet discharge limits will allow ships to treat bilgewater onboard ship, reducing shore side disposal costs. The AAE/CINC combined system, if proven effective, would provide the Armed Forces with a system that would allow ships to process their bilgewater and discharge the effluent overboard without violating discharge restrictions. The design of the system should also reduce the manpower requirement associated with operating and maintaining the system. The compact design of the system would provide ship design managers with a system capable of fitting on most legacy ships. (Anticipated Project Completion - 2012)
