A lab. development-demonstration program was conducted to provide a physical-chemical system for onboard treatment of shipboard wastes. An evaluation of hardware developed during the program and analytical results of tests are presented. The treatment system as developed was shown capable of suspended solids removal from raw sewage using the capillary properties of cellulose sponge to draw liquid through a polypropylene filter screen. The use and effectiveness of a pressure-bed filter and coagulants as filtering techniques were also demonstrated. A series of activated carbon adsorption beds were evaluated for removal of dissolved organic materials, and a chlorination unit with no moving parts was shown suitable for disinfection. Evaluation tests of the overall system indicated a range of BOD reductions between 30% and 90% and SS reductions between 50% and 92%.
