Wastewater treatment systems on four popular cruise ships will receive a $9.2 million upgrade intended to enhance compliance with marine discharge regulations, according to a release issued by Hydroxyl Systems Inc. Hydroxyl, a Victoria-based manufacturer, was recently awarded contracts from Miami-based Royal Caribbean Cruise Lines to design and build four CleanSea environmental water process systems, said the report. The systems will combine Hydroxyl's bio-film carrier process for high-rate biodegradation with its dissolved air flotation equipment, both of which decrease space requirements and system lifecycle costs, Hydroxyl representatives said in the release.
