Abstract
A filter for a vehicular sewage system that includes an elongated body having a plurality of longitudinal vanes and slots. The body is made from a material able to support the growth of biological agents. The slots sized to resist the passage of particles larger than about 0.04 inches. The filters are structured for use with a vehicular sewage system having a treatment tank divided into an upper chamber and a lower chamber by a membrane. The membrane has a plurality of filter openings in which the filters are disposed. The filters allow fluid waste and solid particles smaller than about 0.04 inch flow into the lower chamber. Larger particles of solid waste are exposed to air in the upper chamber thereby allowing aerobic biological agents to process the solid waste. In use, the filter allows the liquid portion of wastewater to pass from an upper chamber of the treatment tank into a lower chamber. The solid waste particles are then consumed by an aerobic bacteria in the upper chamber.
