摘要： This invention relates to a method and apparatus for drying organic material using the energy contained in the organic material to be dried to drive the drying process. The organic material could be sewage sludge, food scraps, manure, wood, bagasse etc. The latent heat of evaporation is recovered through the use of a heat pump mechanism. This allows for the retention of a majority of the heat within the system, allowing optimal drying conditions to be maintained throughout the drying process.

摘要： Systems and methods for producing an organic fertilizer rich in humic substances and nitrogen from waste gases and liquids are disclosed. The methods include forming a mixture of coal and liquid and contacting said mixture with a gas containing ammonia, allowing ammonia react with the coal to release humic substances to the liquid and to complex ammonia with the coal and humic substances controlling the pH of the mixture and forming a humic ammonia rich fertilizer. The systems include a mixing chamber fluidly connected to sources of liquid and coal, a gas contacting chamber, a pH control subsystem, a solid liquid separator and a pathogen deactivator.

摘要： Methods and systems are provided for treating wastewater to simultaneously remove nitrogen, carbon, and phosphorus, while recovering energy in the form of methane and carbon dioxide. An ammonia-containing stream is directed to a pretreatment tank that produces excess sludge, biogas, and a pretreated stream. The pretreated stream has at least 45% less carbon than the ammonia-containing stream. The pretreated stream is then directed to an anoxic tank, which promotes phosphorus release and fermentation of particulate and dissolved organic matter. The mixed liquor is transferred to an aerated tank having low dissolved oxygen concentrations to promote development of phosphorus-release bacteria that is eventually recycled to the anoxic tank by way of the return activated sludge. Simultaneous nitrification, denitrification, and phosphorus release occur in the aerated tank. A membrane tank separates treated effluent from activated sludge in a membrane tank.

摘要： Methods and systems are provided for treating wastewater to simultaneously remove nitrogen, carbon, and phosphorus. The process includes an anoxic tank that receives at least two streams, including plant influent wastewater and return activated sludge. These streams are mixed in the anoxic tank to promote phosphorus release and fermentation of particulate and dissolved organic matter. The mixed liquor is transferred to an aerated tank having low dissolved oxygen concentrations to promote development of phosphorus-release bacteria that is eventually recycled to the anoxic tank by way of the return activated sludge. Simultaneous nitrification, denitrification, and phosphorus release occur in the aerated tank. A membrane tank separates treated effluent from activated sludge in a membrane tank.

摘要： Systems and methods for sequestering carbon dioxide from the environment using biopolymers are disclosed. The methods include forming consumer products using bioplastics or biopolymers, collecting said consumer products after consumer use and stopping biodegradation of said biopolymer. In some embodiments the biopolymer is a non-biodegradable biopolymer while in other embodiments the degradation of the biopolymer is stopped by alternative means. A tracking system of the fate of the bioplastic or biopolymer during the lifecycle of the product is described.

摘要： Methods and systems are provided for reducing ammonia partially by a denitrification process. A stream containing ammonia is contacted with oxygen to form a first product stream in low dissolved oxygen conditions. The ratio of oxygen to nitrogen is about 2.28 g O2/g N—NH3 (2.28 grams of oxygen per gram of nitrogen in ammonia) or less. The first product stream is then exposed to organic matter in an amount of 0.57 g COD/g N—NH3 (0.57 grams of chemical oxygen demand per gram of nitrogen in ammonia). This microbial reaction ultimately produces nitrogen gas, water, and carbon dioxide.
