Trojan Marinex BWT System Receives U.S. Coast Guard AMS Acceptance

Today we are proud to announce that the Trojan Marinex Ballast Water Treatment (BWT) product suite has received United States Coast Guard (USCG) Alternate Management System (AMS) acceptance – in accordance with the USCG’s final rule for Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. waters – for all water qualities: freshwater, brackish water and marine water.

While AMS is an important certification, it is not USCG Type Approval which is Trojan’s main objective. “We remain committed to being one of the first BWT system suppliers to achieve U.S. Coast Guard Type Approval, and continue to take the necessary steps to achieve this goal”, says Marv DeVries, president, Trojan Technologies.

AMS is a temporary designation given to a ballast water treatment system approved by a foreign administration. Vessels operating in U.S. waters may use an AMS-designated BWT system to manage their ballast water discharges in lieu of ballast water exchange – for a period of five years from a ship’s compliance date – while that BWT system undergoes USCG Type Approval testing. AMS certification neither guarantees nor implies that USCG Type Approval is likely, as the two programs are independent of each other.

The Trojan Marinex BWT product suite is tested and IMO Type Approved to the lowest UV transmittance value in the industry (corresponding to poor water quality) under full flow conditions. Testing was conducted under the supervision of DNV – who is certified as an Independent Lab (IL) by the USCG – in accordance with United States Environmental Protection Agency (USEPA) Environmental Technology Verification (ETV) Ballast Water Protocol. The ETV protocol is a key testing requirement for systems to obtain USCG Type Approval.

Orange County Water District Wins Lee Kuan Yew Water Prize

Lee Kuan Yew PrizeCongratulations to the Orange County Water District (OCWD) on winning the prestigious 2014 Lee Kuan Yew Water Prize for its pioneering Groundwater Replenishment System (GWRS).

The prize – awarded during Singapore International Water Week – is an internationally-recognized water award that highlights outstanding contributions towards solving global water problems either through the use of innovative technologies or by implementing policies and programs that benefit humanity.

OCWD’s research and demonstration efforts have established the industry standard for potable water reuse in the industry as a three-stage advanced treatment process consisting of microfiltration, reverse osmosis and UV-oxidation.

The TrojanUVPhox™ system is installed in OCWD’s Groundwater Replenishment System (the world’s largest indirect potable reuse facility). The system includes UV reactors, a storage and metering system for hydrogen peroxide and an Optiview UV transmittance monitor.
