A fifth manufacturer, Ecochlor, has applied for type-approval from the US Coast Guard (USCG) for its ballast water management system (BWMS). Once approved, this will add another technology option - chlorine dioxide - to those already available from USCG type-approved systems.
Its application was submitted on Friday (31 March) and Tom Perlich, Ecochlor’s president and founder, told BWTT today (3 April) that it followed “three years and more than US$4 million for supplies, testing and labour.” Because it is one of the first manufacturers to pursue USCG type-approval, he added, “there have been delays as Ecochlor has worked diligently with DNV GL to finalise testing and reporting procedures.”
Those tests “clearly indicate that the Ecochlor system will meet and, in most cases, exceed USCG discharge criteria,” he said in an earlier statement.
As a result of its progress, “our expectation is that Ecochlor’s market share will grow significantly in the near future,” Mr Perlich told BWTT. “We are in discussion with many shipowners that have been waiting for us to reach this step in our USCG type-approval process prior to purchasing a system.”
The system already has IMO type-approval and approvals from six class societies. These include DNV GL, which it appointed as its independent laboratory “to secure DNV GL classification society approval simultaneously with USCG Type Approval,” its statement said.
Ecochlor reported that the system’s chemical dosage had been reduced for USCG type-approved systems and that its effectiveness is not impaired by variations in salinity, temperature, turbidity, organics, or vibration. It advised that the price and size of a chlorine dioxide generator does not vary greatly based on flow rate. “As a result, chlorine dioxide generators are much more economically viable over other systems in the treatment of large volumes of water,” it said.
