Managing BWT Costs and Compliance

Bill Burroughs

Managing systems costs, redundancy are key to Ballast Water Convention Compliance. The current market position for ballast water treatment systems is similar to the early phase of the introduction of oily water separators. Eventually, the systems that did not work reliably were forced out, but at great expense to shipowners. While some ballast water treatment system manufacturers struggle to meet the regulatory and operational requirements of global trade, regulators are still…

ALPURE Ballast Water Treatment System Successfully Completes Corrosion Testing Program

FORT WASHINGTON, Pa. – 9 March 2011 – The BALPURE ballast water treatment systemfrom Severn Trent De Nora satisfies corrosion test recommendations of the IMO MEPC 59/2/16. The corrosion testing, performed by an independent third-party institute, proved the BALPURE system has no effect on coated steel, naval bronze and Cu-Ni alloys. Testing proved an insignificant effect on bare steel – so small that the acceleration of corrosion due to the presence of free chlorine has minimal practical implications in ballast tanks.
