The system is designed for a continuous flow with automatic operation. The system does not require any chemicals.
The first stage removes the free oil by gravity with the help of coalescence plates. An adjustable oil sensor controls the valve for automatic oil release to the sludge tank or any other dedicated tank. The adjustable oil sensor makes it possible to minimise the amount of treatable water released to the sludge tank.
In the second stage emulsified oil is removed in the two filter tanks and the ppm value is monitored by a 15-ppm bilge alarm, before the treated water is discharged overboard. The collected free oil on top of each filter tank is released automatically to the sludge tank at a pre-set interval. When a 15 ppm alarm occurs, the 3SEP OWS will automatically close the overboard line and re-circulate the treatable water to the bilge. When the contamination falls below 15 ppm the overboard valve will open again without human intervention.
The system is designed as a skid assembly with all connection points collected, for easy installation. When the unit reaches the customer the only remaining thing to do is to connect water inlets and outlets and the electrical power supply, facilitating quick and easy installation onboard. Before leaving our workshop each unit has to pass a quality-test, where all functions are tested.
All equipment has the highest quality; the tanks are made of acid proof stainless steel, AISI 316L. Our pumps are supplied by internationally recognised brands. Spare parts are easily available from one of our offices or representatives worldwide
