AbstractNot Available The comminutors and transfer pumps used to process and discharge sewage from Navy vessels are the two primary components requiring the most service/maintenance. When the comminutors fail, oversized solids enter into the Collection, Holding and Transfer (CHT) system used to process shipboard soil and waste drain discharge. These large solids can subsequently clog the sewage discharge pump (SDP), disrupting system functionality and forcing sewage to be discharged into restricted waterways which is in direct violation with Secretary of Defense promulgated regulations. To correct this situation a new or modified pump must be engineered that will eliminate the need for the communitor. This new pump must be capable of either passing the largest solids that can flow through system piping or reducing the size of incoming solids using integral chopping mechanisms. In Phase I, system requirements will be established and a design for an advanced SDP will be developed. The proposed principles of operation for this new SDP will be verified through proof of feasibility testing using modified pumps tested on simulated waste streams. The Phase I results will provide the baseline foundation for developing prototype SDPs that can be tested on actual shipboard waste in a follow-on Phase II program.
