Evaluation and Optimization of the Peroxide Regenerated Iron Digester Enhancement (PRI-DETM) Technology for Enhancement of the Anaerobic Digestibility of Mixture of Primary and Secondary sludge.

Anaerobic digestion of waste for biological methane and hydrogen production can be a sustainable source of renewable energy as well as an efficient waste management technique. Significant research efforts on digester design, process enhancement, and odors control are vital. In 2009, US Peroxide (a wholly owned subsidiary of Trojan Technologies) developed the peroxide regenerated iron digester enhancement (PRI-DE™) to enhance the anaerobic digestibility and reduce odor and scaling. This technology combines the use of iron salts with hydrogen peroxide (to regenerate the iron to Fe2+ and/or Fe3+) under pressure. Though successfully deployed for collection system and primary clarification applications, the PRI-DE™ technology has yet to be validated experimentally in lab and field trials. In this study, the effect of using the peroxide regenerated iron digester enhancement (PRI-DE™) on the sludge characteristics will be investigated taking into consideration different process parameters such as hydrogen peroxide dose, level of pressure, pH….
