Meticulously designed and built for use in the marine and offshore environment, Oily Water Separator (“OWS”) provides unparalleled solution for oily/bilge water treatment, for better ocean pollution control. Equipped with the latest technology and premium quality parts, our OWS is able to achieve treated water with oil content less than 15ppm, meeting the IMO Regulations MEPC 107(49).

15ppm Bilge Alarm
A bilge alarm is commonly used in connection with OWS, specifically designed to monitor the oil content in bilge water. Conforming to the IMO Regulation MEPC 107(49) regulation, the 15ppm bilge alarm type BILGMON 488 provides precise accuracy in measuring the oil content through its unique measuring cell and simple operation.
When the oil content exceeds the 15ppm limit, the alarm will be activated and the overboard discharge terminated.
Oily Water Separator 15ppm Bilge Alarm Features

  • Fitted with a 15ppm bilge alarm device (oil content monitor); BILGON 488, tested and approved in accordance with IMO Regulation MEPC 107(49).
  • An automatic bypass is fitted to the separating system to extend the lifespan of the demulsifier. When the water quality falls below 15ppm, the demulsifier is bypassed until the 15ppm alarm is activated. This control ensures a prolonged lifespan of the absorber elements.
  • A 3-way valve is installed downstream of OWS in the overboard line for recirculating the water to the bilge (automatic stopping device.)
  • Capacity from 0.2m³/h to 10.0m³/h available, suitable for all kinds of vessels
  • DNV class type approved
