EVALUATION OF A PROPRIETARY WASTE TREATMENT SYSTEM ABOARD THE USCGC ALERT (WMEC-630) BASED AT CAPE MAY, NEW JERSEY

A shipboard aerobic waste treatment system utilizing hydraulic comminution, vacuum aeration gravity settling and filtration, was field tested and evaluated to determine its effectiveness in reducing suspended solids, biochemical oxygen demand (BOD) and coliform density. The system was installed on the CGC ALERT (WMEC-630) based at Cape May, New Jersey. Influent and effluent waste properties were determined. Influent wastes consisted of sanitary, galley, scullery, shower and lavatory wastes, and discharges from deck drains below the water level. Physical modifications to the system were made in an attempt to improve its performance. A detailed description of the system's operation and an evaluation of its performance are included. (Author)
