The new Carbon Absorption Bio-oxidation System (CABOS) for the treatment of sewage on board commercial vessels has been developed by the Ontario Research Foundation under contract from the (Canadian) Department of Fisheries and Environment. It includes sewage flow equalization, carbon absorption, bio-oxidation, filtration, and ozone disinfection; and has been evaluated on a Canadian Great Lakes bulk carrier owned by Scott Misener Steamships Ltd. The results were satisfactory. The average effluent quality ranged from 6 to 25 mg/1 in BOD (Biochemical Oxygen Demand) and 5 to 13 mg/1 SS (Suspended Solids) as compared with the Canadian Government requirements of 50 or less of each. Regular crew members were able to perform all operational and maintenance tasks, without the need for a full-time specially-trained operator. A production prototype is being built for installation in another Scott Misener vessel.
