Some Technical and Economic Concerns Relating to Shipboard Pollution Abatement

摘要

Three questions related to abatement of pollution from Naval vessels are examined. Current candidates for shipboard sewage treatment application are discussed with respect to limitations of development imposed by technical processes utilized. Limited flush with incineration and biological treatment are judged ready for application with the latter method less desirable for several secondary reasons. Wet air oxidation is also considered a good candidate. Open ocean impact of oil and sewage discharge is the second area examined. The third discussion involves an examination of the economic factors related to contract sewage treatment shows that it is most probable that the Navy can work with municipal authorities to their mutual advantages. Reasonable amounts of salt water do not reduce efficiency of biological plants of the aerobic variety.
