ABSTRACT:
An on-board treatment device and method for use on watercraft and other mobile vessels are provided. The system includes a treatment tank which is connected to the head and a bioreactor and a feed pump which are connected to the treatment tank. A macerator pump breaks up solids in the wastewater before the wastewater enters the treatment tank. During a treatment cycle, a head valve prevents any further flow of wastewater from the head into the treatment tank. Also during a treatment cycle, a bioreactor 3-way valve will be set so that the feed pump will flow wastewater from the tank, through the bioreactor, and back into the treatment tank. The bioreactor will include microorganisms which are adapted to the treatment of human waste. When the wastewater has been sufficiently treated, the feed pump will be turned off so that solids in the wastewater can settle out. After the solids have settled out, the feed pump is turned on and the bioreactor 3-way valve is set so that the now treated wastewater is discharged overboard. In a preferred embodiment the bioreactor includes an aerator.
