Appl. No.:

09/819973

Inventors:

Gary A. Tipton - Houston TX
Douglas E. Fessel - Waterville MN

Assignee:

EcoKasa Incorporated - Houston TX

International Classification:

E03B 1100

US Classification:

210170, 2105322, 405 44, 405 45, 405 50

Abstract:

The present invention is a compact water dispersal system located on an outdoor ground site. The system includes a water treatment system resulting in treated water with an organic loading of less than about 20 ppm and a suspended solids concentration of less than about 20 ppm. The water flows from the water treatment system to an interior discharge pipe having a plurality of perforations. Through the perforations, the water flows into an exterior discharge pipe surrounding the interior discharge pipe, the exterior discharge pipe also having a plurality of perforations. The exterior discharge pipe is surrounded by a layer of wicking material. A volume of fill material surrounds the interior discharge pipe, the exterior discharge pipe, and the layer of wicking material, thereby dispersing the water therefrom.

Abstract:

A compact nitrogen reduction wastewater treatment system for treating a waste liquid, the system comprising a single tank. The tank includes an inlet, an aerobic treatment compartment, an anoxic treatment compartment, a suspended micromedia compartment, an aerator, and a tank outlet. The aerobic treatment compartment includes aerobic treatment bacteria and is in fluid communication with the tank inlet. The anoxic treatment compartment is laterally disposed relative to, and in fluid communication with, the aerobic treatment compartment. The suspended micromedia compartment includes separating media. It is positioned laterally relative to, and is in fluid communication with, the anoxic treatment compartment. The suspended micromedia compartment is also laterally disposed relative to, and in fluid communication with, the aerobic treatment compartment. The aerator injects air bubbles into the suspended micromedia compartment, thereby causing at least some of the waste liquid to recirculate to the aerobic treatment compartment.
