Robust and reliable filters designed specifically for the challenges of Ballast Water Treatment

  • Best available technology for self-cleaning.
  • Duplex stainless steel housing – designed for the lifetime of the ship!
  • Dramatic weight savings – less than half the weight of conventional filters.
  • Reduced and simplified maintenance.

Flexibility: Inlet/outlet and backwash flanged connections are easy to adapt to customer needs

  • Fully automated filter.
  • Communication with any BWTS/Vessel automation system.
  • Support for performance data storage.

MossHydro’s Duplex stainless steel housings enable weight reduction of 50-70%:

  • The tensile and yield strength of Duplex stainless steel is substantially higher than for conventional materials.
  • No sand blasting, no primer, no coating and no rubber lining - due to its inherent corrosion resistance.
  • No corrosion protection is needed.
  • A lighter overall solution allows easier installation, foundation and support.
  • Therefore less maintenance and potential damage to filter housing.

MossHydro single screen filters are available for the following flow rates:

  • 250 m3/hr
  • 350 m3/hr
  • 425 m3/hr
  • 500 m3/hr
  • 700 m3/hr
  • 880 m3/hr
  • 1.000 m3/hr
  • 1.350 m3/hr






Configuration and flow rates: A range of other flow rates can be achieved by parallel combinations of two (paired) or more (battery) of the standard units:

  • Battery: Any flow rate at a 250 m3/hr step.

Available for installation in gas hazardous (Ex) areas
