Marine Industry

Headworks BIO is a global leader for environmental wastewater process technology within the marine industry. The DNV certified CleanSea® turnkey wastewater treatment process enables cruise vessels and ferry fleets to economically meet stringent discharge regulations throughout the world.

Major cruise lines rely on the CleanSea® technology to operate within environmentally sensitive coastal regions, including Alaska State, which has the toughest marine discharge standards in the world. With CleanSea® systems reliably exceeding strict Alaska State discharge requirements, Headworks BIO's cruise industry customers can maintain focus on their core business, secure in the knowledge that the environmental impact of their operations is economically minimized.

BC Ferry Services, Ltd. operates the largest and most sophisticated ferry fleet in the world, with ten CleanSea® Oxidation compact shipboard wastewater treatment systems in service. This large ferry system relies on CleanSea® oxidation technology to reliably discharge, safe and disinfected water within environmentally sensitive coastal regions of British Columbia, Canada. 

Incorporating marine industry-proven components and Headworks BIO patented processes, CleanSea® technology delivers environmental capabilities specifically designed to meet the tough requirements necessitated for reliable, long-term shipboard operation. Every CleanSea® system is optimized for customized application within site-specific shipboard layouts, ensuring optimum functionality within space constrained areas of every CleanSea® equipped vessel. 

CleanSea® technology is equipped to efficiently treat any blend of marine wastewater streams including grey water streams from accommodation, galley, food reject water, and laundry sources as well as black water.

Moving Bed Biofilm Reactor (MBBR) technology is the biological core of the CleanSea® process. The multi-stage MBBR process achieves high-rate biodegradation of organic matter within a compact, economically operated system. MBBR biofilm carriers establish a high-density population of bacteria within the process; this bacteria naturally oxidizes organic wastewater constituents, reliably biodegrading target constituents from process wastewater streams prior to discharge. This unique technology enables biodegradation within a highly compact shipboard design that optimized for reliable IMO type certified operation.
