The US Coast Guard's (USCG) rejection of test method for US ballast water treatment systems (BWT) represents a serious setback for the suppliers of these systems.

For the four suppliers BWS systems that use ultraviolet light (UV) to clean the water, the rejection " is a serious setback for this type of technology," says head of section Torben Madsen of DHI, Danish Hydraulic Institute, which tests ballast water treatment systems.
