Rapid on-board testing of treated ballast water to ensure compliance with the IMO D-2 & USCG Discharge Standards.


Invasive species cause devastation to marine habitats worldwide. In 2004 the International Marine Organisation (IMO) introduced the Ballast Water Management Convention to prevent the spread of harmful organisms through ballast water. All ships must now meet the IMO D-2 Performance Standard which states that discharged ballast water must not contain more than 10 viable cells/mL in the 10-50 μm size range (smallest dimension).


Features & Applications



  • Rapid on-board compliance testing to the IMO D-2 standard
  • Detection limit of <1 cell/mL
  • Accurate cell count regardless of cell size
  • Compliance-level testing in only 2 to 10 minutes
  • Stirred sample allows accurate statistical analysis
  • Negligible false positives, avoiding unnecessary delays in port
  • Very low levels of false negatives allowing confident ballast water discharge
  • High tolerance to background fluorescence from dead cells and CDOM
  • Minimum consumables and no costly reagents or laboratory testing required
  • Long service interval (>2 years)
  • Optional flow-through system can provide continuous testing during ballast water discharge.
