- Efficient nitrogen (N) management is crucial for environmental and economic sustainability, particularly in livestockintensive regions where manure is abundant. Ammonia stripping-scrubbing (SS) offers a promising method for N recovery from manure, but its real-life implementation has been limited. Integrating SS before nitrification-denitrification (NDN) in existing plants can enhance treatment capacity and recover N while maintaining low N effluent levels, yet cost estimations after process optimization for this approach are lacking. To address this, a programming model was developed and calibrated, using SS experiments at a full-scale facility, to minimize treatment costs and optimize the balance between N recovery and removal by optimizing operational parameters for 18 scenarios with varied setups, influent characteristics, and scrubber acids. Results indicate that implementing two-stage SS before NDN can reduce overall costs by 1-56% compared to NDN alone. LF of manure treatment shows cost reductions of 1-8% with 22-29% N recovery, while LF of codigested manure treatment achieves cost reductions of 11-56% with 42-67% N recovery. This study underscores the power of modelling in achieving minimum-cost design and operation of manure treatment processes. By utilizing SS followed by NDN, it is possible to realize significant cost savings while simultaneously producing valuable N recovery products.
