Abstract: The present disclosure provides an apparatus comprising a primary treatment system configured to remove solids from an untreated fluid to generate a primary treated fluid. The apparatus further comprises an oxidation treatment system including an inlet configured to receive the primary treated fluid, an ozone inlet configured to receive ozone from an ozone generator, and an outlet configured to dispense secondary treated fluid. The apparatus may further comprise a controller in electrical communication with the ozone generator. The controller is programmed to regulate the flow of ozone through the oxidation treatment system such that an effective amount of ozone contacts the primary treated fluid to generate the secondary treated fluid. In some embodiments, the secondary treated fluid discharging from the oxidation treatment system has a chemical oxygen demand (COD) removal level of greater than 85%.

Abstract: Disclosed herein are processes, systems, and catalysts for improving pyrolysis technology. The disclosed processes and systems utilize a catalyst to increase pyrolysis gas (py-gas) and decrease bio-oil yields in pyrolysis reactions. The disclosed catalysts may include biochar derived from pyrolysis of industrial residuals, such as pyrolysis of wastewater biosolids (WB) and paper mill sludge (PMS). The disclosed catalysts also may include ash derived from incineration of wastewater biosolids (“biosolids incineration ash” (BIA)).

Abstract: Disclosed herein are methods for improving performance of an anaerobic digester system. The methods typically include adding a culture comprising hydrogenotrophic methanogens to the system, otherwise referred to as bioaugmentation.

Abstract: Disclosed are drying methods for preserving cultures of methanogens and dried cultures obtained by the disclosed drying methods. The dried cultures of methanogens may be reconstituted and utilized to bioaugment anaerobic digester systems.
