20160017589 | LIQUID WASTE TREATMENT APPARATUS - A fluid conduit with layered and partial covering material thereon is disclosed. The fluid conduit may be used for processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused and/or returned to the earth and particularly to the water table. The fluid conduit may be of many forms and types and may have attached thereto and configured thereon covering material in partial form and a selected number of layers. The fluid conduit may be a septic pipe of smooth wall, of corrugated form, and/or of any form of cross-sectional configuration including circular, elliptical, rectangular, triangular, or any other geometric shape. The fluid conduit may be used in combination with conduit in a drainage field or leaching system usually associated with a septic tank or septic system. | 01-21-2016 |
20150329396 | Modular Liquid Waste Treatment System and Method - A modular liquid waste treatment system is disclosed. In accordance with some embodiments, the system includes a central distribution unit and one or more treatment fins in flow communication therewith. The distribution unit may be configured to receive liquid waste from a given source and distribute that waste, at least in part, to one or more treatment fins. In turn, bacteria present in a given treatment fin treat the liquid waste, and the resultant treated liquid may drain from the fin to the surrounding environment. In some embodiments, a given treatment fin may include porous media providing a large surface area on which bacteria may grow to facilitate treatment. The system may be installed in and/or above the ground, and in some cases may be surrounded, at least in part, with treatment sand and/or other treatment media. The system may be used in aerobic and/or anaerobic processing of liquid waste. | 11-19-2015 |
