Abstract: In a system and process, organic waste is treated in a reactor to volatilize contaminants such as Perfluoroalkyl substances (PFAS) compounds and/or Contaminants of Emerging Concern (CECs) from the organic waste. Biochar may have reduced or undetectable PFAS compounds or CECs. Most or all of the gas may be thermally oxidized to convert PFAS compounds and/or CECs into less harmful and/or less toxic products or elemental compounds, which may be further removed. Energy may be recovered from one or more parts of the herein described system and process.

Abstract: In a system and process, sludge from a wastewater treatment plant is treated in a high solids digester, optionally a mechanically mixed wet digester. Sludge (i.e. digestate) from the anaerobic digester is thickened or dewatered. Part of the thickened or dewatered digestate is thermally hydrolysed. The hydrolysed digestate may be, or may be further treated to produce, Class A biosolids. The hydrolysed digestate can be dewatered producing a liquid fraction that is recycled to the digester. Another part of the thickened or dewatered digestate is returned to the digester. The return of thickened or dewatered digestate to the digester allows for a smaller tank to be used (compared to a system without a recycle of thickened or dewatered digestate) while maintaining the same solids residence time (SRT) and volatile solids reduction (VSR). In some examples, the hydraulic residence time (HRT) of the digester is 10 days or less.

Abstract: The specification describes a system and process for treating a sludge or slurry to produce biochar. The sludge or in slurry may be digestate produced by an anaerobic digester that receives waste activated sludge from a wastewater treatment plant. In a process, digestate is dosed with metal ions, dewatered, and pyrolized. A corresponding system includes a reactor, a dewatering unit and a pyrolysis unit. In an example, the digestate is air stripped in the reactor and a metal salt is added to it. The metal ions form precipitates in the digestate that remain in the biochar. In some cases, a precipitate such as struvite is formed that also increases the phosphorous content of the biochar. The biochar may be used as a soil amendment, wherein the metal and phosphorous are beneficial to the soil.

Abstract: An anaerobic digester is fed a feedstock, for example sludge from a municipal wastewater treatment plant, and produces a digestate. The digestate is dewatered into a cake. The cake may be dried further, for example in a thermal drier. The cake is treated in a pyrolysis system to produce a synthesis gas and biochar. The gas is sent to the same or another digester to increase its methane production. The char may be used as a soil enhancer.

Abstract: Waste, such as municipal solid waste (MSF) or a portion of MSW, is separated into a wet fraction and rejects in a press. The press produces a wet fraction and rejects. The wet fraction may be treated, for example by anaerobic digestion or compost to thereby divert waste from landfill. The waste is pre-treated by spraying water at high pressure against the waste while moving or mixing the waste. The pre-treatment increases the amount of cellulosic material, such as paper or cardboard, that passes into the wet fraction.

Abstract: Organic waste is treated by pyrolysis or by anaerobic digestion followed by pyrolysis of the digestate. The pyrolysis is performed in two staged reactors. The second stage reactor treats char produced in the first stage. The temperature of the first stage reactor is preferably 450 degrees C. or less. The temperature of the second stage reactor is higher than the temperature of the first stage, for example by 50 degrees C. or more. Optionally, there may be a char cooler, a water sprayer, or both downstream of the char outlet of the second reactor. In an exemplary system, a digestate outlet is connected to the inlet of the first pyrolysis reactor. A pyrolysis liquid outlet of the first pyrolysis reactor is connected to the digester. Char produced in the second pyrolysis reactor may be used as a soil amendment.

Abstract: A waste stream is treated by anaerobic digestion. A process is described involves a step of separating solids from digestate, and returning separated solids to a digester. Optionally, there may be a step of solids separation in which larger solids are removed from the digester. A process and apparatus are described for treating waste sludge from a wastewater treatment plant in an anaerobic digester. Feed sludge is thickened or solids are separated from digestate and returned to the digester. Additional co-digestion waste may be added to the digester. The process and apparatus may be used in a retrofit of an existing wastewater treatment plant.

Abstract: Low strength wastewater such as municipal sewage is treated using an anaerobic digester. In some examples, a wastewater stream is separated into a solids rich portion and a solids lean portion. The solids lean portion is treated, for example to remove nitrogen. The solids rich portion is treated in an anaerobic digester, preferably with influent or recuperative thickening. In another example, the wastewater stream is fed to an anaerobic digester and solid-liquid separation stages downstream of the digester return active bacteria and undigested organics to the digester. Both cases may use a process train comprising treatment in an anoxic tank followed by a nitritation tank with a portion of the effluent from the nitritation tank recirculated to the anoxic tank to provide nitritation and denitritation.

Abstract: An apparatus for recovering nutrients or water from digestate comprises one or more solid-liquid separation units, an ammonia stripping device, and a gas scrubbing unit. In a process, digestate is separated into a solids portion and a liquid portion. Ammonia is stripped from the liquid portion and converted into an ammonium salt solution which may be sold or used as, or blended with, a fertilizer product. Optionally, at least part of the remaining liquid portion may be concentrated to produce brine. The brine is mixed with the solids portion. The mixture may be dried and used as, or blended with, a fertilizer product. Optionally, a least part of the remaining liquid portion may be re-used as dilution water in a digester. A solids portion of the digestate, and one or both of an ammonium salt solution and a brine, may be used as fertilizer without thermal drying.

Abstract: In a waste treatment system and process, relatively low and high solids concentration streams are treated in generally parallel anaerobic reactors. The reactors may share a common wall or gas collecting cover. The reactors may also share a common downstream aerobic treatment unit. Solids produced during downstream treatment of effluent from one or both anaerobic reactors may be returned to the high solids concentration stream. The low solids concentration stream may be treated in an attached growth anaerobic digester.
