TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises heating the recycle water before separating toxic compounds. It further comprises removing gases produced from the step of anaerobically digesting and combining the removed gases or converted compounds with the dewatered solids effluent. The method further comprises adding start-up water to the influent slurry before anaerobic digestion. It further comprises pretreating the influent slurry. The influent slurry is pretreated to produce a sludge. It is macerated into a homogeneous mixed slurry. The method further comprises adding bulking conditioners to the dewatered solids effluent. The method further comprises adding conditioning substrates to the influent slurry to increase gas production, where the conditioning substrates include carbonaceous substrates deficient in nutrients. The method further comprises adding conditioning substrates that include nitrogen, phosphorus, potassium or sulfur. The step of anaerobically digesting converts 40-80% of the biodegradable solids that are in the diluted influent slurry. The method further comprises adding a reagent including polymer, flocculant, coagulant, ferric chloride, ferric sulfate, or ammonium sulfate. The method further comprises concentrating the dewatered solids effluent and returning the liquid recovered from concentrating to the recycle water. The step of removing toxic compounds comprises the use of a physical, chemical, or biological process, where the toxic compounds include ammonia, hydrogen sulfide, or organic acids. The method further comprises converting toxic compounds into nitrates, sulfates, carbonates, elemental sulfur, iron sulfur compounds, ammonia compounds, organic compounds containing nitrogen and sulfur, or a salt. It further comprises combining the separated toxic compounds or converted compounds with the digester effluent. Preferred Component: The influent slurry is combined with a material containing cellulose, or anaerobic bacteria. ACTIVITY - Fertilizer. No biological data given.
