Abstract: A unique compact, biphasic, MEthanogenesis and ANaerobic Ammonia (ME-ANA) system for one-step Carbon(C) and Nitrogen(N) removal from the wastewater Partial Nitrification–ANAMMOX (PN/A) based process is a promising biotechnological solution to remove nitrogen from ammonium-rich wastewater. But, the efficiency of PN/A processes is affected by the presence of dissolved organics. Therefore, a pretreatment step is required for the removal of dissolved organic matter from the wastewater which increases operational cost and footprint area. The present invention relates to design and development of compact, biphasic, biological, MEthanogenesis and Anaerobic Ammonia (ME-ANA) system for one-step carbon(C) and nitrogen(N) removal from domestic and industrial wastewater over wide range of influent C/N ratio (0.5 to 18) and at a wide range of operating temperatures (5 °C to 40 °C). In ME-ANA, the organics-removing phase and ammoniacal nitrogen-removing phase are mounted in a single system, reducing the footprint area. The unique configuration of ME-ANA does not need aeration or multiple pumping units for organics and ammoniacal nitrogen removal, thereby, improving treatment and effectively reducing the operational and maintenance cost.
