TREATMENT OF WATERCRAFT WASTES

A demonstration program of electro-chemical processing of shipboard sanitary, culinary, and laundry wastes including prolonged sea trials on board a large vessel was conducted. Extensive analytical results are presented demonstrating ability to produce effluent of secondary water quality standard and to incinerate system by-products. Substantial data for the design of shipboard systems is also presented. The economic viability of the treatment system developed is analyzed and compared with alternative approaches with the conclusion that dependence of large vessels on shore side facilities in conjunction with on-board holding equipment is eliminated in many cases. The program demonstrates the the unique character of shipboard wastes and the shipboard environment verifying the need for specially developed equipment for treatment such as the system demonstrated. The program suggests further extension of the capabilities of the system developed for increase in capacity and for elimination of other ships wastes such as bilge water and wet and dry garbage.
