6.6 Coalescing bed-type oily water separators The coalesce is capable of forming oil globules up to l2 mm diameter and the heavier fuel oils usually form long 'stalagmites' which grow to a considerable size before they are released. Because of the 1ow velocities employed the collected oil can flow past the water screen without becoming re-entrained and carried through into the outlet

6.5 Cleaning the Comyn oil/water Separater To clean out the separator ensure that all oil possible has been drawn off through the oil recovery valve and scum valve, and that the separator is full of water. Turn on steam to heating coil; also steaming out connection, and allow the separator to become thoroughly hot

General Operating Procedure Before pumping oily water into the separator it is important that the separator is completely filled with clean water, either direct from the sea or through the filling valve provided for this purpose. It is essential to keep the lower internal surfaces and outer chamber from becoming coated with oil

A fire and bilge pump has suctions from sea, bilge main and engine room bilge, with discharges to fire main, oily water separator and overboard. A ballast pump has suctions from sea, ballast main, engine room , bilge direct and bilge main with discharges to overboard, the ballast main, the oily water separator and possibly, the main salt water circulating system
