Abstract: A wastewater treatment system for use on marine vessels or land-based applications where wastewater is separated into two separate sources as graywater and raw sewage (blackwater). For blackwater, the treatment system incorporates five general phases (or zones): (1) screening, (2) clarifying, (3) filtering, (4) advanced oxidation, and (5) sludge reducing. For graywater, the treatment system incorporates three general phases (or zones): (1) screening (2) filtering, and (3) advanced oxidation. Each train of the treatment system (blackwater and graywater) can operate as a stand-alone system or can be assimilated into an integrated treatment train for both graywater and blackwater. This system is particularly useful in today's restrictive regulatory environment.

Abstract: A sludge reduction system that reduces the volume of solids contained in a fluid medium such as a wastewater stream. The system reduces the disposal burden and reduces odors by oxidizing organic material such as raw or activated sludge in an ozone oxidation zone and then separating the concentrated sludge for extraction in a concentrated sludge extraction zone. The sludge reduction system is particularly useful in applications such as cruise ships because (1) the reduction of sludge saves space and energy costs, and (2) the reduction of odors permits shipboard treatment rather than holding in tanks for later discharge.
