Regenerable biocatalytic nanofiltration membrane for aquatic micropollutants removal [PDF]

, 2018
A trade-off between operation stability and activity regeneration limits the application of biocatalytic membrane, and when it is applied for micropollutants removal from drinking water under flow-through mode, a high removal efficiency is required.

Effect of Ion Sizes on Separation Characteristics of Nanofiltration Membrane Systems [PDF]

, 2006
The effect of the ion size on salt rejection is investigated using the Donnan steric pore model (DSPM). This model accounts for the transport phenomena occurring inside the membrane through the appropriate ion sizes.

Modeling of NF/RO membrane fouling and flux decline using real-time observations [PDF]

, 2019
Many numerical models for membrane filtration have been developed to explain and predict fouling mechanisms. The models can simulate flux decline, transmembrane pressure increase, and fouling thickness based on theoretical equations.
