6. 8 Instructions for dvz-oily water separator After first set to operation it takes some time until the air is bleeded from the separator and bilge suction pipe This is indicated by irregular lighting up the lamp oil to sludge tank After some time the system stabilizes automatically Under normal operating conditions more water than oil flows through separator. So it takes some time until the sensing electrode is surrounded by oil, because the oil buffer is growing from top to bottom. If surrounded by oil, the sensing electrode gives a signal via the niveau relay to the automatic switch box The valve"A3. 1 opens and the pump turns left, The pump is sucking from sea now and with that seawater the separated oil is pressed out to sludge tank via valve"A3. 1. During this state the non return valve a1. 1?' is dosed to avoid the back flow to bilge/bilge tank6.8 Instructions for DVZ-oily water separator – After first set to operation it takes some time until the air is bleeded from the separator and bilge suction pipe. This is indicated by irregular lighting up the lamp “oil to sludge tank”. After some time the system stabilizes automatically. – Under normal operating conditions more water than oil flows through separator. So it takes some time until the sensing electrode is surrounded by oil, because the oil buffer is growing from top to bottom. If surrounded by oil, the sensing electrode gives a signal via the niveau relay to the automatic switch box. The valve “A3.l” opens and the pump turns “left”. The pump is sucking from sea now and with that seawater the separated oil is pressed out to sludge tank via valve “A3.l”. During this state the non return valve “A1.1” is dosed to avoid the back flow to bilge/bilge tank
