Oil Recovery and Sludge Treatment

The MSPX separator is designed to handle oily sludge with a high concentration of impurities and large density variations. The separated sludge is recirculated to the sludge tank. Recovered oil is fed to the waste oil tank and cleaned water to the bilge water tank.

Without proper training, potential problems may include:

  • Excessive volume of oil waste
  • Frequent and costly sludge disposal
  • Insufficient sludge storage space
  • Unreliable burning of sludge in incinerators

Bilge Water Treatment System

Alfa Laval's pure bilge oily water treatment system is the first system to obtain the 5ppm DNV type approval certificate. For bilge water, clean design stipulates a maximum 5ppm of oil remaining in the water after treatment, prior to pumping overboard. MARPOL regulations stipulate 15ppm. In 2011, DNV introduced a 5ppm type approval process for marine bilge water separators.

Without proper training, potential problems may include:

  • Poor, inefficient separation results
  • Unnecessary maintenance
  • Problems with US coast guard inspection
  • False alarms

Conventional Separation System

The 'P' separation system is suitable for cleaning marine and power station diesel oil, fuel oil up to 600cSE, and lubricating oils.

Without proper training, potential problems may include:

  • High maintenance cost
  • Frequent alarms due to lost water seal
  • Poor, inefficient separation
  • High oil/fuel losses
  • Confusion over gravity disc selection
