Large and Small Pulpers

Overview

The pulpers were designed for shipboard use on U.S. Navy vessels. They are key elements in the Marine Pollution Controls systems for shipboard solid waste management to meet the Act to Prevent Pollution from Ships ("APPS") and MARPOL (Marine Pollution) Annex V. A pulper processes food, cardboard and paper waste (including classified documents) into a non-floating slurry that discharges overboard. The small pulper is intended for smaller size ships that do not have the space or require the high processing capability of the large pulper.

Applications

Both pulpers are designed to resist damage if trash sorting errors occur and metal, glass, or other non-pulpable materials are placed into the unit. Metal and glass debris that may not have been sorted before it was loaded into the pulper are separated from the slurry by means of gravity, forced to the bottom of the tank and collected in a "junkbox," which is emptied manually after the pulper is shut down. Plastic items inadvertently loaded into the pulper are partially shredded and retained within the pulping chamber. They are removed manually after the unit is shut down.
