SPEL Separator and Econoskim systems are constantly monitored. With the manual system, an alarm signal is given when the level of hydrocarbon pollutants reaches 90% of the oil storage volume for which the separator has been designed in accordance with the Environment Agency’s Pollution Prevention Guidelines PPG3.

The pollutants, oil, fuel and other light liquids are then skimmed off the surface in the main separation chamber into the SPEL Tankstor containment tank. When the light liquids have been skimmed off, the valve is closed and the alarm reset ready for the next cycle. Unless silt is accumulating in the primary chamber, or separate silt trap, an emptying tanker will not be required until the SPEL Tankstor containment tank is full. For total, efficient control and operation the ‘automatic’ system is available.
