Problems solved by technology

However, the moisture is not evenly distributed and based on the practice of some solid waste, it is extracted and not replaced, thereby keeping this waste in place until a later time after the maintenance fund is exhausted and through site cover corrosion and water intrusion processes that introduce solid waste into stormwater to allow the waste to be bioconverted to methane

Embodiment Construction

[0036] Desired degradation of organic compounds by hydrogen-producing bacteria as long as hydrogen partial pressure can be kept below -4 Atmospheric pressure will happen.

[0037] No single species of bacteria produces all the extracellular enzymes required for the degradation of the large variety of particulate and colloidal substrates found in solid waste and other biomass. Each exoenzyme, as well as each endoenzyme, only degrades a specific substrate or group of substrates.

[0038] Therefore, a large and diverse population of bacteria is required to ensure that the appropriate types of endo- and exo-enzymes are available to degrade existing substrates. Table 3 exemplifies the enzymes required for certain substrates, while Table 4 exemplifies how enzymes are used in the critical pathway for the formation of methane from solids.

[0039] Methane gas production by anaerobic bacteria can be facilitated by coenzymes. Coenzymes are metal-loaded organic acids that are introduce...

Abstract

A bio vapor stimulation system may include components for mixing bacteria and nutrients and for growing bacteria, as well as process sensors, and a novel delivery system to provide an appropriate balance of: (1) anaerobic bacteria, (2) nutrients, and (3) humidification in a carrier gas for deposition through condensation, into selected volumes of a landfill (or other coal or biomass resources), as determined by various sensors. Measurements of the landfill site conditions, the landfill gas, the landfill gas condensate for temperature, pH, alkalinity, COD / BOD, gas composition; oxidation-reduction potential (ORP), volatile acid concentration, and / or other parameters may be used as process control inputs. Based upon these measured indicators of the health and status of the anaerobic bacteria community within the site, various process changes may be administered such as bacteria composition, additives, nutrient composition and quantity, temperature and ph of delivered liquid feed into carrier gas for the site humidification, to thereby establish and / or restore an efficient biologic environment for the conversion of organic waste or other carbonaceous materials into methane.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority of US Provisional Application US 61 / 345,012, filed May 14, 2010. Background technique [0003] The moisture content of incoming solid waste to landfills is usually sufficient to provide complete conversion of organic matter to methane. However, the moisture is not evenly distributed and based on the practice of some solid waste, it is extracted and not replaced, thereby keeping this waste in place until a later time after the maintenance fund is exhausted and through site cover corrosion The introduction of solid waste into storm water through the process of water intrusion allows the waste to be bioconverted to methane. [0004] Anaerobic conversion of waste to methane requires a large number of bacterial families and a large number of process steps that break down solid waste into components and gases that can be converted to methane by methanogens. The better the e...
