HYDE GUARDIAN-US BWTS COMPLETES USCG TYPE APPROVAL TESTS

Friday, January 10, 2020 

The Hyde Guardian-US (Universal Service) Ballast Water Treatment System (BWTS) has successfully completed all requirements of an Independent Laboratory, and is under review by the US Coast Guard for Type Approval.

Hyde Marine, a wholly-owned subsidiary of Calgon Carbon Corporation, says this represents the final step before the USCG’s final determination and indicates that the Independent Laboratory has recommended that the system meets the requirements for discharging ballast within the waters of the United States.

Testing of the system was conducted in challenging ‘sweet’ fresh water with less than 1 psu, with water down to a UVT level in the 40’s, and with the minimal holding times able to be processed by the test facility during the test cycles.  The system was proven to have no potential for regrowth in the ballast tanks as many tests were conducted with extended hold times.

Hyde Marine has more than 500 of its BWTS sold to date. The Hyde Guardian-US BWTS uses space efficient filtration and ultraviolet disinfection, which closely mirrors the existing Hyde Guardian-Gold product, and customers can easily upgrade their existing equipment to meet the new treatment standard.

“Hyde Marine is very pleased to have completed this process,” said Chris Todd, Executive Director of Calgon Carbon UV Technologies. “During shipboard testing, we used one of our first customers as an upgrade platform to prove we could retrofit one of our earliest systems to our newest product.  Our test plans proved a strenuous test of our system’s functionality, conclusively proving our ability to modulate flow to ensure proper dose, and demonstrating the effectiveness of our industry-exclusive Treatment Alarm.”

The Hyde Guardian-US BTWS was tested with water containing organism counts far exceeding IMO and USCG requirements and was tested with the most demanding water conditions to challenge the limits of system performance.  “We are confident that our system can perform to the expectations of our clients anywhere their vessels may go,” said Todd.

Hyde Marine’s new system features full, automatic flow regulation to ensure that as water quality changes, the system manages the entire treatment process to achieve compliance. Hyde Marine has also developed and tested an exclusive alarm which provides crews an indication that the system may be operating outside of the as-tested boundaries.  This alarm allows crews to initiate contingency measures for potentially non-compliant water before arriving at the discharge port. This ensures that de-ballasting and cargo loading are not impacted.
