  • Marine sewage disposal device
    Patent number: 3951803
    Abstract: A marine sewage disposal device connectable to a toilet and flushed by water, in which the sewage is macerated to small particle size, subjected to heat and electric current to destroy coliform bacteria, and subsequently filtered to separate liquids from solids prior to being discharged. Power requirements are relatively low, in the order of 2 to 5 amperes at 110 volts A.C., or less, thereby permitting the device to be used on relatively small craft having minimal generating equipment, such as a standard generator arranged to bypass the usual voltage regulator.
