Ammonia recovery from industrial wastewater is gaining more and more attention. Due to the environmental impact the regulations for ammonia emissions are becoming stricter, and the need for improved processes is growing. An alternative to conventional technology is TransMembraneChemiSorption, using hydrophobic membranes for controlled mass transfer from liquid through gas-filled pores into liquid absorption fluid. This study presents some information about operating data, basic layout and the restrictions of a full-scale industrial system, as well as an analysis of this new technology compared with common processes. Carrying out plant-scale measurements, a model has been evaluated which makes it possible to establish mass transfer calculations for hollow fiber membrane contactors. The resulting total mass transfer coefficient equals existing ones from literature.
