6. 4 The Comyn oil/water Separater 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

6.4 The Comyn oil/water Separater 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

6.4 The Comyn oil/water Separater To fill the separator, slightly open scum-valve, also high level test and air release valve to vent the separator during filling. When water flows freely from these valves close and stop filling Close filling valve Before commencing to pump oily water through the separator, ensure that water discharge valve on ship's side is open to allow the water effluent to be pumped overboard

6.4 The Comyn oil/water Separater • To fill the separator, slightly open scum-valve, also high level test and air release valve to vent the separator during filling. When water flows freely from these valves close and stop filling. Close filling valve. • Before commencing to pump oily water through the separator, ensure that water discharge valve on ship's side is open, to allow the water effluent to be pumped overboard

6.4 The Comyn oil/water Separater Slightly open both mixture inlet test valve and high-level test valve. Leave these two valves slightly open during the working of the separator. mixture inlet test valve will indicate the nature of the mixture entering the separator. while high-level test valve will free the separator of air and also denote the presence of oil within the oil recovery dome

6.4 The Comyn oil/water Separater • Slightly open both mixture inlet test valve and high-level test valve. Leave these two valves slightly open during the working of the separator. Mixture inlet test valve will indicate the nature of the mixture entering the separator, while high-level test valve will free the separator of air and also denote the presence of oil within the oil recovery dome

6.4 The Comyn oil/water Separater Procedure using automatic control Switch on the electronic control panel. If water completely covers the electronic probe the green indicator light will show. Alternatively if the water level in the oil dome, after Filling, is below the level of the electronic probe, the red indicator light will show, in addition to the green indicator light and the alarm bell will ring

Alternatively, if the water level in the oil dome, after Filling, is below the level of the electronic probe, the red indicator light will show, in addition to the green indicator light, and the alarm bell will ring

6.4 The Comyn oil/water Separater Check that the emergency hand control wheel e fitted to the automatic oil outlet valve is in the open position Check that the operating air or water pressure is 14-3.5bar. Open air or water supply to solenoid pressure control valve

6.4 The Comyn oil/water Separater • Check that the emergency hand control wheel fitted to the automatic oil outlet valve is in the open position. • Check that the operating air or water pressure is 1.4-3.5 bar. • Open air or water supply to solenoid pressure control valve

6.4 The Comyn oil/water Separater On commencing to pump oily water into the separator, the clean water surrounding the electronic probe causes the coil of the solenoid pressure controller to become energized and move the pilot valve to the open position, closing the outlet previously open to vent. Air is permitted to pass to the top of the diaphragm operated oil discharge valve and immediately closes it As the pressure within the separator builds up to approximately 0. 75 bar the spring-loaded water discharge valve opens

6.4 The Comyn oil/water Separater a gradual build-down of oil takes place, which, in time, completely covers the electronic probe At this juncture the control unit de-energizes the coil of the pressure control valve, returning it to the open to vent position. This permits the spring assisted oil recovery valve to open, and any oil present within the separator is automatically discharged back to the oil storage tanks The red and green indicator lights will show on the control panel
