Texas Business Patent Of The Day: Two Ellis County residents devised a new way to process sewage in an old way.
Kenneth J. Kistner and Carolyn R. Kistner, both of Midlothian, received U.S. Patent 8,110,096 for “Septic System.”
The Kistners filed for the patent on April 11, 2011.
The Kistner’s invention relates generally to fluid systems and, more particularly, to septic systems, according to the patent document.
Septic systems are well known in the art for disposing waste material found in gray water, black water, sewage, and the like and are typically used in rural residential areas where city sewage systems are unavailable.
Septic systems include one or more tanks for storing and treating liquid waste. After treatment, the effluent is leached from the septic system and deposited in the soil surrounding the septic system. Under ideal conditions the septic systems effectively remove odors, waste material, and harmful bacteria from the liquid waste. The effectiveness of the process varies considerably upon different factors, including the capacity of the system in relation to the number of persons utilizing the facilities serviced by the septic tank and the type of waste matter entering into the septic system.
Enzymes and/or other organisms are typically added to the liquid waste, which in turn effectively disposes of the waste material.
Commercial enzymes, such as RID-EX, effectively decompose the waste matter in the liquid waste. It should be understood that merely adding enzymes will not result in the full decomposition of the waste material. For example, some enzymes have the tendency to settle to the bottom of the tank, never reaching the floating waste material. In addition, some septic systems do not provide sufficient time for the enzymes to dispose of the waste material.
The Kistners’ system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system. The aeration subsystem includes a compressor section that compresses the liquid waste and an injector section that injects oxygen into the compressed liquid waste.
The system further includes a driver subsystem for driving the compressor section and a control subsystem for activating and deactivating the driver subsystem.
