SKF has launched the Sludge Buoy system, a new mechanical device that allows for the continuous gravity separation of free oil in tanks.
It is a ‘fit and forget’ solution, requiring almost no maintenance or electricity for its operation as it is entirely mechanical.The use of this new system allows for resulting water in the tanks to be much cleaner and easier to process in the bilge water separator, boosting its efficiency and reducing costs.
Turbulo Sludge Buoy’s Operation
The oil in the tank flows into the Turbulo Sludge Buoy’s lower compartment at a maximum rate of 6m³ per hour. It is then either pumped out or flows out under gravity depending upon whether the drain is below or above the surface of the water. This separation at the source enhances environmental performance according to ISO 14001.The free water content of the separated oil is quite low, less than five per cent. Consequently, it requires no further treatment and can be disposed of either in an on-board incineration plant or ashore.
The system eliminates the need for consumables or spare parts for the lifetime of the system and the payback time is particularly short, normally less than a year.
According to SKF this technology can solve the problem of filter clogging.
