文摘

An analysis of mass transport, thermodynamics and PRO module scale modelling was conducted. A state-of-the-art TFC hollow fiber membrane was employed in modelling. The asymmetric nature of hollow fibers results in more significant ECP in lumen side. A trade-off relationship exists between power density (PD) and specific energy (SE). The PD vs. SE trade-off upper bound provides a guidance to optimize PRO module operation.
