Abstract
A method and apparatus for the production of a methane rich biogas from a septic tank for the purposes of electricity production involves the modification of conventional septic tank designs and the supplementation of genetically modified methanogenic bacteria. Biogas produced from modified or newly installed septic systems is collected and stored for electricity generation in external gas powered generators. To optimize the energy potential of this septic tank gas apparatus, a method of supplementing domestic waste within the septic tank with methanogenic microbes is implemented. Genetically enhanced methanogenic bacteria are supplemented to the septic system to improve gas production and overall power efficiency of the apparatus.
Description
Title Septic Waste-to-Energy Method and Apparatus Field of the Invention The present invention relates to the improvement of conventional septic tanks used for the treatment and storage of domestic wastes. The field of this invention pertains to the Background of the Invention The purpose of septic tanks is small-scale sewage treatment: to collect waste generated by the occupants of a dwelling, and to disperse water such that it will not cause damage to the environment. It is common in areas without connection to government or corporation's main sewage pipes.
Septic tanks are widely used, including suburbs, small communities, rural areas, and corporations.
Septic tanks consists of an inlet wastewater pipe connecting the dwelling's plumbing to one or several tanks, which connect on their opposite ends to an outlet wastewater pipe that enters a drain field. The tank itself is divided into two chambers, which are separated by a vertical dividing wall with openings. The tank relies on indigenous anaerobic bacteria present to break down the wastewater entering it. Wastewater discharged from the household plumbing (toilet, sinks, laundry, etc.) travels through the inlet wastewater pipe and enters the first fluid-filled chamber, solids settling at the bottom and scum floating at the top.
The sunken solids are anaerobically decomposed, reducing their volume. The liquid component flows through the dividing wall into the second chamber, where further scum-solid separation occurs. The solid is again broken down and the liquid drains through the outlet into a leach field (i.e. drain field or seepage field). The drain field receives the effluent via a network of perforated pipes laid in gravel-filled trenches or beds. Wastewater trickles out of the pipes, through the gravel layer, and into the soil. The soil below the drain field provides the final treatment and disposal of the effluent, purified via biological and chemical processes of the soil.
Current septic tanks that are used to generate electricity do not take full advantage of the natural gas released by bacteria. The invention described uses genetically modified bacteria to target an increase of methane gas for electricity generation. It is a process by which we can generate a sustainable cycle of renewable energy production from waste excretion.
The anaerobic environment promotes fermentation, leading to the generation of carbon dioxide and methane. Methane is a potent greenhouse gas and stores a considerable amount of potential energy.
Manure, feces, and other organic materials are all carbon sources that anaerobic bacteria can ferment into methane (CI-14). This natural gas can be collected, stored, and converted to electricity. Furthermore, the amount of gas generated by a septic tank can be increased, for increased electricity production and storage. Generators convert natural gas to electricity by the motion of turbines, converting mechanical energy to electrical energy. Septic tanks rely on indigenous anaerobic bacteria already present in the tank to break down. Current septic tanks that are used to generate electricity do not take full advantage of the natural gas released by bacteria.
Summary of the Invention The invention described will use genetically modified bacteria to target an increase of methane gas for electricity generation. It can thus be seen that the present invention provides a novel method of energy generation from septic tank, which successfully integrates genetically modified bacteria to increase the methane production to convert to electricity via a series of piping, tanks, and a commercial generator. The electricity stored in the generator can be used for energy, including powering the dwelling and consequently decreasing the electricity bill.
The invention pertains to existing or new septic tank systems. More specifically, the invention relates to a process by which dwelling wastewater is expelled, with additional genetically modified bacteria, via the plumbing system, through the inlet pipe into the septic tank. Through the addition of the gene responsible for the bacteria's capacity to produce methane from the wastewater, the new bacteria contributes to septic tank's existing bacteria mass in its ability to yield natural (sewer) gas. The gas rises to the top of the tank and is gathered by a gas trap. The gas trap collects the methane and the gas travels through piping to storage tanks. The storage tanks keep in reserve the natural gas, which is then fed through a commercial generator to generate electricity.
The invention possesses numerous benefits and advantages over known methods of septic energy harnessing. While the references described in the prior art section may be adequate for their intended purposes, they do not encompass all the elements covered by our method for the purpose of energy production. For instance, it was believed that a methane-digester was impractical, as typical septic tanks do not foster the conditions that existing anaerobic organisms need to produce a significant amount of gas. This problem is solved by genetically modifying additional bacteria to amplify the amount of methane produced to a significant level, such that it can be stored and converted into a useable amount of electricity.
Additional features and advantages of the present invention will become more apparent from the detailed description that follows, taken in conjunction with the accompanying drawings.
Brief Description of the Drawings FIG. 1 is a side view of the septic tank component of the system, showing a cross-section of the tank.
FIG. 2 is a side view of the overall apparatus, featuring the septic tank system transitioning from the home to the leaching field underground. The gas collection apparatus is aboveground from the septic tank and includes the connections of the gas trap pump, storage tanks and generator.
FIG. 3 is an overview of the gas enhancement procedure in septic tank system.
Description of the Preferred Embodiment With reference to the drawings and, in particular, with reference to FIGS 1 and 2, the waste-to-energy apparatus consists of a septic tank and a series of gas collection devices including a gas pump, storage tanks and a commercial generator. FIG 1 illustrates a cutaway view of the septic tank portion of the apparatus. Noted in the figure is the inlet pipe (4), which supplies the tank with domestic waste from the residential toilet and sinks pipelines. It is from this inlet source in which waste and supplemental bacteria are able to enter the tank for anaerobic digestion and biogas production. Also shown in FIG 1 are gas outlet (3) and liquid outlet (5). The gas outlet carries the accumulating biogas out of the tank and into the aboveground gas processing equipment (not shown in this figure). The liquid outlet drains clarified water into the leaching field (also not shown in FIG 1) similar to that of conventional septic systems.
FIG 1 shows the extra insulating layer (6) composed of either concrete and/or other conventional encasing material. Much of the septic tank in FIG 1 resembles that of typical septic tanks, with the emphasis being on the crucial addition of the gas outtake pipe. Features like a baffle (1) and access ports (2) are common in most septic tanks on the market today.
FIG 2 is a comprehensive overview of the apparatus, and similarly, the method for generating electricity from enhanced bacteria in septic tanks. The figure shows the components of the apparatus that are aboveground and underground and a simplified case of the equipment's arrangement. As examined in FIG 1, the septic tank is shown in FIG 2 as well, labelled as (11). The leaching field (12) drains water underground and downslope from the septic tank, a feature that is common in virtually all septic systems today. Notable features in FIG 2 include the gas processing equipment of the apparatus, consisting of the gas pump (17), storage tanks (16) and gas generator (15). Each of these components is electrically activated and controlled from a controller inside of the house (13). The electricity from the generator is fed into the house's power supply (14). Access ports (20) are sealed shut as to eliminate the penetration of the oxygen inside the tank, or the release of biogas outside of the tank.
Genetically modified bacteria are delivered through the inlet port from the house's plumbing (12).
FIG 3 is an overview of the gas enhancing method involving a genetically modified methanogenic microorganism that has been optimized to produce methane gas from domestic wastes. As a general procedure, bacteria cultures with the optimized anaerobic bacteria can be flushed down the toilet or dumped down the sink to encourage an increased gas production rate from the bacteria already existing in the septic tank system.
