Catch microplastics with a bilge filter

Wave international has created a bilge filter system called Wavestream. It comes in four sizes to fit all ranges of marine craft and is fitted after the bilge pump to remove microplastics (and oil and impurities) from the bilge water to ensure that no traces of pollutants are discharged overboard.

63% of shrimp in the North Sea have been found to contain synthetic fibres.



  • Small and lightweight
  • Easy to fit
  • Keeps discharged bilge water below regulation required 15 or 5 ppm levels


  • To remain effective, cartridge changes should be part of a regular maintenance schedule and changed at least every season
  • Upfront cost.

Making a difference

Bilge filters ensure that you reduce the discharge of microplastics into the marine environment.
