Abstract
In response to increasingly stringent environmental regulations the Canadian Navy has chosen to replace the currently fitted SAREX coalescing Oily Water Separation (OWS) system with a more robust and effective system. After reviewing the available technologies Director General Maritime Engineering Project Management/Director Marine System Support 4 concluded that a membrane based OWS system would provide the best solution for bilge water treatment. Accordingly, after soliciting bids from various companies a contract has been let with Water Technologies International of Burlington, Ontario to provide 16 such systems to the Canadian Navy over the next three years. While a membrane based system can meet all naval (compactness, automation and operational effectiveness) and environmental requirements it is anticipated that some difficulties will be encountered in placing a new system aboard HMC Ships. Thus, it is prudent to study the system in order to identify and understand its optimal performance and attempt to anticipate any difficulties that may be experienced with its operation. To optimize the system performance the following parameters warrant study: membrane pore size, operating pressure, cost-flow velocity, the frequency and level of backpulse pressure and cross-flow velocity surges.
