Trojan Technologies has received alternate management system (AMS) acceptance from the US Coast Guard (USCG) for its Marinex ballast water treatment (BWT) product suite.

Acceptance of the AMS is in accordance with the USCG’s final rule for standards for living organisms in ships’ ballast water discharged in the US waters, for all water qualities; freshwater, brackish water and marine water.

Trojan Technologies president Marv DeVries said: "We remain committed to being one of the first BWT system suppliers to achieve US Coast Guard type approval and continue to take the necessary steps to achieve this goal."

"Marinex BWT product suite is tested and IMO type approved to the lowest UV transmittance value in the industry under full flow conditions."

AMS-designated BWT systems are used by vessels operating in US waters to manage their ballast water discharges in lieu of ballast water exchange for a period of five years from a ship’s compliance date, so that that the BWT treatment system undergoes USCG Type approval testing.

The company said that the Marinex BWT product suite is tested and IMO type approved to the lowest UV transmittance value in the industry under full flow conditions.

DNV, a USCG-certified independent lab (IL), along with the US Environmental Protection Agency (USEPA) Environmental Technology Verification (ETV) Ballast Water Protocol is responsible for supervising the suite testing.
