The Enhanced Biogas Production process is designed to retrofit existing conventional wastewater treatment plants by allowing them to recover ammonia from anaerobic digesters and thereby enhance the efficiency of the digesters. The technique can be used with or without the Company's ARP technology. It can also be implemented with Temperature Phased Anaerobic Digestion to make more biogas and destroy pathogens. Temperature phasing is a relatively new method adopted by wastewater treatment plant operators that uses two phases of anaerobic digestion. In the high temperature phase, waste solids are disinfected and conditioned (around 120 - 140°F) to reduce pathogens below threshold levels and solubilize some of the solids during the digestion phase. The Enhanced Biogas Production process is intended to be a cost-effective method of processing and treating animal waste from concentrated animal farming and in which the waste is converted into two saleable commodities: (i) energy in the form of methane; and (ii) ammonium sulfate, a commercial grade fertilizer. This process can be integrated with ThermoFuel and used in conjunction with municipal and industrial wastewater applications that use aerobic or anaerobic digestion.
