<p>A sewage treatment device including a macerator and pumping assembly for use with a toilet of the type utilized in recreational vehicles, such as boats, trailers, or the like. The assembly is mounted near the bottom of a toilet bowl with the macerator adjacent to the outlet of the bowl. The macerator and a pump impeller are mounted on a common shaft rotated by a motor. The impeller is mounted behind the macerator for discharging macerated sewage to waste. The macerator is an auger-like element having a point and a pair of blades formed with spiral-shaped leading edges converging toward the point. The macerator effectively macerates solid waste and conveys the same axially toward the impeller for rapid evacuation from the toilet bowl with a minimum consumption of water from the bowl.</p> |
