Zusammenfassung:	This report documents work in two areas: (1) investigate the environmental impact of shipboard paper pulper discharge in the ocean, and (2) evaluate the effectiveness of enzymes for cleaning membranes in Navy shipboard graywater systems. Field tests were conducted to measure paper pulp concentrations behind a U.S. Navy frigate using a shipboard paper pulper. These measurements helped validate a model being used by the Navy to predict wake dilution rates. For the enzyme tests, experimental protocols were developed and used to run tests on several different enzyme types to determine their cleaning effectiveness on fouled membranes used to filter graywater.
