PROBLEM SOLVING EXPERIENCE IN THE TREATMENT OF SHIP'S SEWAGE ON THE GREAT LAKES

Prior to the 1971 Great Lakes shipping season, two operating companies installed prototype physical-chemical sewage treatment systems aboard vessels in their fleets. The two systems underwent extensive development and refinement during the 1971 season. All shipboard liquid wastes generated outside the engine room were treated including toilets, galley, laundry, showers and lavatories. Two more systems were installed during the 1972 Season and four more during the 1973 Season. Two additional units were built for Spring 1974 installation. The system refinement program has continued up to the present. Midway through the 1973 Season, an effluent monitoring and control system was installed on the Str. "John Sherwin" of the Interlake Steamship Fleet. Effluent turbidity and coliform content were continuously monitored and recorded through the end of the season. Independent laboratory tests were also conducted during this period. The monitored results, lab test results and data collected from other installations are presented. Many problems involving the variation of system effluent characteristics, hydraulic loading, shipboard environment and crew operation and maintenance were encountered. These problems, their solutions and the reasons for choosing this particular system design are discussed.
