    Abstract: Systems and methods are disclosed in which ammonia may be recovered efficiently from wastewater through the application of the mass-transfer reaction kinetic model. The recovery process may involve the stripping of NH3 from wastewater by aeration and the absorption of this stripped NH3 gas into a recovery solution by utilizing stoichiometric acid-base reactions and the operating parameters optimized by the model which facilitate both processes. Another step may be performed in which saturated solution comprising the recovered NH3 may be further evaporated and liquefy to produce a pure bioammonia product. Applying the mass-transfer reaction kinetic to the recovery can not only enhance the NH3 removal and recovery yield but also increase the NH3 removal and recovery rate. Numerous operating parameters can be adjusted to maximize the recovery yield and recovery rate.
