Method for recycling organic waste material
A method for recycling organic waste material containing phosphorus oxides and metal oxides is particularly suited for recycling sewage sludge. The waste materials are mixed with chlorine carriers and then heat-treated at an air ratio of 0.851.6 and at least partially oxidized. The metal chlorides thus formed are drawn off and recovered and the fraction remaining after the metal chlorides have been drawn off is subjected to reduction in order to obtain elemental phosphorus.
SYSTEM AND METHOD OF TREATING ORGANIC MATERIAL
A system and method of treating organic material using active species are disclosed. The system and method can be used to treat the organic material before introducing the organic material to a biodigestion reactor. The active species can include, for example, ozone, and can be used to, for example, kill microorganisms, sterilize the organic material, reduce volatile organic compounds, degrade or break down toxins and/or pharmaceutical compounds in the organic material, and/or increase the surface are of the organic material.
Method for treating animal waste
Methods and apparatus for the treatment of animal waste are disclosed, together with a treated animal waste and fertilizer and growth media products derived therefrom.
Treatment method for complete harmless treatment of activated sludge and complete resource utilization of activated sludge's products
The present disclosure provides a treatment method for complete harmless treatment of activated sludge and complete resource utilization of activated sludge's products, belonging to the technical field of activated sludge treatment. The treatment method provided by the present disclosure comprises ultrasonic treatment, microwave treatment and/or vapor treatment, solid-liquid separation, microbial mineralization treatment, acidification treatment, and other steps. In the present disclosure, various steps are collaborative with one another, can successfully and completely convert activated sludge into organic fertilizers, ferrite materials, industrial silica sol and other products, thereby achieving the complete utilization of activated sludge. Furthermore, the obtained products have high quality, and all meet related quality standards. The present disclosure can solve the problems of complete resource utilization of activated sludge that cannot be achieved in the prior art, poor economic benefits, complicated process and the like, and is suitable for industrial development.
PROCESS FOR TREATMENT OF SEWAGE SLUDGE
A method for pathogen destruction in dilute sewage sludge or other dilute streams containing pathogens, including Helminth ova, while minimizing vapor generation and atmospheric emissions. In addition to conventional waste treatment steps, including grit removal, clarification, and concentration of waste material, vaporized waste treatment compounds are recycled to treat divert untreated waste in a scrubber. In the scrubber, waste material is treated while also acting as a reactive agent to scrub potentially hazardous or noxious gas, particularly gaseous MITC, from the treatment system. Recycling of vaporized treatment compounds provides a reduction of potentially toxic emissions and increased efficiency during treatment.
System and process for reducing PFAS and microplastics in biosolids using hydrodynamic cavitation and foam fractionation
A system for reducing particles from biosolids, comprising a storage tank for holding biosolids and an inlet pipe. The inlet pipe delivers biosolids from the storage tank to a screener and then to a percent solids meter. The percent solids meter measures the solid content in the biosolids and sends a signal to an electronic solenoid valve to control water content of the biosolids introduced to the system. A first venturi hydrodynamic cavitation to create vacuum bubbles in the biosolids. A mechanical hydrodynamic cavitation device operably connected to first venturi hydrodynamic cavitation, wherein the mechanical hydrodynamic cavitation device creates vacuum bubbles in the biosolids.
Digestion of organic sludge
The invention is in the field of organic sludge digestion from various sources, such as manure, sludge from a wastewater treatment plant, and an organic fraction of dredging sludge. The present method provides advanced control for serially treating aqueous organic sludge by anaerobic digestion. It further relates to dewatering of the obtained biomass.
Thermomechanochemical waste treatment
Apparatus and systems are provided for processing PFAS-contaminated waste via thermomechanochemical (TMC) processing. In one example, a system may include a TMC processing chamber including a milling system and coupled to a heating system, the heating system configured to co-operate with the milling system to process the waste material. A plurality of containers including the waste material in one or more of a liquid-solid state, a semi-wet or slurry solid state, and a dry solid state are coupled to the TMC chamber.
