Therefore, there is a great interest in the recovery of ammonia from, wastewater, for the transformation of the N life cycle. Air-stripping followed by acid absorption has been well-established as an effective process for ammonia recovery from wastewater (Liu et al., 2015; Tao and Ukwuani, 2015; Xiong et al., 2018; Zeng et al., 2006).
