Optimarin has moved to reinforce its market leading position by challenging the integrity of its filter components, through a rigorous program of testing in conjunction with Det Norske Veritas (DNV). The initiative, understood to be unique for a ballast water treatment (BWT) system supplier, saw Optimarin make a substantial investment to put its three leading filter suppliers – Boll & Kirch, Filtersafe and Filtrex - to the test at Goeje Island in South Korea. The motivation was simple; to challenge, and ultimately demonstrate, the reliability of this most crucial BWT system component (giving potential and existing customers real peace of mind), while also feeding the test results back into the Optimarin and individual supplier development teams in a drive for ever-greater performance.
