UV DISINFECTION specialist Hanovia has teamed up with fluid handling specialist Hamworthy to provide a new range of ballast water treatment systems designed to meet the UN’s International Maritime Organisation’s standards ahead of the IMO Ballast Water Management Convention.

This partnership comes as the two companies have been working together for many years on marine black and grey water systems. It combines Hanovia’s UV technology and Hamworthy’s experience in water filtration to meet environmental legislation, a joint company statement said.

Hanovia’s UV systems design is a chemical-free technology for ballast water treatment. Medium Pressure UV is said to be particularly advantageous due to its small environmental footprint, ease of maintenance and low capital and running costs.

The company also makes its own UV lamps and monitors, to suit specific ship requirements. “UV performance is critically dependent on the combination of UV light source, UV monitoring technology and chamber fluid dynamics,” the statement said.

“Apart from the need to perform to regulatory requirements under a wide range of seawater conditions, shipowners need treatment systems to have a small footprint and that lend themselves to both new-build and retro-fitting into what remaining space there is on existing ships,” said the company statement.

Hamworthy is assuming overall responsibility for performance compliance against the required regulatory standards.
