COST EFFECTIVENESS STUDY OF WASTEWATER MANAGEMENT SYSTEMS FOR SELECTED U.S. COAST GUARD VESSELS. VOLUME IV. DEVELOPMENT OF CANDIDATE SYSTEMS

Eighteen system concepts for managing black (sewage and garbage grinder slurry) and gray (galley and turbid) wastewaters aboard six different U.S. Coast Guard Cutters are presented. Specific equipment configurations (number of units, model, capacities, etc.) necessary to synthesize each Wastewater Management System (WMS) concept on each vessel are given. The 18 WMS concepts were synthesized as hybrids of five commercially available Marine Sanitary Devices (MSDs), namely, Jered, GATX, Chrysler, Grumman, and a CHT (Collection, Holding and Transfer) system. For purposes of hybridization, each MSD was analyzed in terms of two subsystems, namely, the waste collection/transport subsystem and the waste treatment/disposal subsystem. The 18 WMS concepts were selected on the basis of MSD subsystem combinations which were judged to have a good chance of succeeding without requiring extensive engineering changes, redesign, and elaborate testing. In MSDs whose treatment/disposal subsystem includes an incinerator in addition to other treatment equipment (Chrysler and Grumman), the substitution of a holding for the incinerator was also considered. Each WMS concept was then analyzed as a function of the vessel to determine the equipment configuration required to synthesize that concept on the given vessel. This determination was made on the basis of the holding time requirements established in the vessel mission profile study (Volume VI), assumed waste generation rates and the crew size. The WMS configurations for each vessel were developed without regard to installation considerations.
