摘要： A method of processing sewage. Non-biodegradable solids are first removed from the sewage for separate disposal. The sewage is then introduced to the bottom of a fermentation cell designed to optimize sedimentation and methane fermentation of settleable organic solids, most of which settle in the fermentation cell. Sulfate-reducing micro-organisms that release sulfides are growing in the fermentation cell. The sulfides released combine with multivalent metal particles in the sewage to form insoluble particles, a portion of which settles in the fermentation cell. The remaining metal sulfides, other suspended solids, microorganisms, nutrients, and pathogens in the sewage are then removed by natural means followed by Dissolved Air Flotation, Slow Sand Filtration and disinfection. Metal ions that escaped sedimentation in the fermentation cell are adsorbed by microorganisms that have a strong negative surface charge. Finally, reverse osmosis is carried out to produce purified water and a high-salinity concentrate. The purified water and the high-salinity concentrate, being substantially free of toxic multivalent metal particles, can be used respectively for safe human consumption and for cultivation of halophilic microalgae.

摘要： This invention pertains generally to anaerobic digesters, and more particularly to a system and process that extends the range of acceptable biomass feedstock concentrations and provides pH process control of all known digestion processes: by the creation of a vacuum or vacuum retort in or before the digester that essentially acts to boil off excess liquid, thickening the liquor of the digester to an optimum value; and to control the pH of the various phases or stages of digestion by separating the component products of digestion and mixing or diffusing a portion of said component products into the mixing system of each phase of the process. A system and process: that produces a potable water effluent, clean commercially useful by-products, zero environmental emissions, a very positive ecological impact; and, that has the capability of being completely self powered plus providing energy back to the community or industry that supports or owns it.

摘要： A system is disclosed comprising a first anaerobic digester, an ammonia recovery vessel, and a second anaerobic digester. Microorganisms within the first anaerobic digester are primarily hydrolyzers and acetogens, and microorganisms within the second anaerobic digester are primarily methanogens. A nitrogen containing feed stock is passed to the first digester in which the feed stock is treated to accomplish hydrolysis and acetogenesis. An effluent stream from the first digester is passed to the ammonia recovery vessel in which ammonia is removed to generate a low ammonia effluent stream. The low ammonia effluent stream is then passed to the second digester in which it is treated to accomplish methanogenesis, thereby generating a biogas. In an alternate embodiment, a single anaerobic digester is used, an effluent stream is removed from the reactor, treated for ammonia removal, and recycled to the digester at a rate sufficient to keep ammonia levels within the digester sufficiently low to avoid ammonia inhibition problems. The systems may be operated under mesophilic or thermophilic conditions.

摘要： A sealed tank includes a concrete footing, a steel or concrete shell ring and a sealed and corrosion-resistant dome having a double membrane. There is an inner membrane delimiting, with the surface of the liquid effluent contained in the shell ring, a sealed chamber intended to receive biogas that results from the methane fermentation or from a corrosive environment. An outer membrane envelopes the inner membrane and which, when pressurized, applies a given pressure to the volume of biogas or of corrosive environment contained in the chamber.

摘要： An in situ method and system for reductive dechlorination, the precipitation of chromium, the precipitation of heavy metals, and microbial denitrification. The invention comprises the formation of in situ anaerobic reactive zones to precipitate and filter out dissolved heavy metals as metallic sulfides, to degrade nitrate to nitrogen gas, to reduce chlorinated hydrocarbons to ethene, and to precipitate and filter out chromium. The invention is comprised of an injection well or wells that extend into a contaminated groundwater. A conduit located within the injection well conveys a reagent to the contaminated groundwater. The reagent may be a carbohydrate rich solution. Microbes digest the carbohydrates to produce sulfate reducing and methanogenic conditions within the reactive zone that include a dissolved oxygen level less than about 0.5 mg/l, a redox potential less than about −250 mv, and a dissolved organic carbon to contaminant ratio of greater than about 50:1. These biogeochemical conditions lead to the reduction of PCE to TCE to DCE to VC and eventually to ethene. These biogeochemical conditions also lead to the precipitation of heavy metals, the precipitation of chromium, and microbial denitrification.

摘要： Described is a method and a device for purifying waste water, in particular by means of anaerobic purification. The method is carried out in a waste water- and sludge-receiving container under generation of gas, the developing gas being trapped by a gas collector and the circulation formed by the ascending gas being used for loosening the sludge which has settled on the bottom of the container. Such a method is to be developed in a constructionally simple and more efficient way. To this end the settled sludge should be sucked from the bottom by a gas lifting effect provided by the ascending gas, and should be passed into the upper portion of the container in a condition separated from the waster water in the container, and returned into the waste water.
