  • Publication number: 20030234086
    Abstract: Recently developed proceedures refine home septic tank effluent to a clean, odorless liquid, but the problem of daily disposal of hundreds of gallons of efflluent remains. Currently this fluid is emptied into the soil, a stream, or slow-evaporation ponds. Frequently, none of these methods are possible at an otherwise desirable homesite. Therefore, a compact, relatively inexpensive, and above all, quick acting process is needed.
