ABSTRACT:
A method and apparatus for treating wastewater such as sewage are disclosed. Designed principally for complete on-site wastewater treatment and disposal, the system separates wastewater into liquid wastes and solid wastes by filtration, treats the liquid wastes with a mild oxidizing agent and disperses them into unsaturated ground. The solid wastes are periodically removed, along with used portions of the paper filter medium and delivered, in the case of sewage, to a composting area where the still-fresh solids can be aerobically composted. Preferred and particularly advantageous embodiments of a filtering system, a sewage delivery system, a vacuum generating system, and a liquid level sensor, each of which may be used with the invention, are disclosed.
