Thermodynamics of Polyamide Separation Membrane in Contact With Aqueous Solutions
… of relative humidity. Water solubility in polyamide active layer is 12 wt% at a relative humidity of 95%. The slope of a water concentration versus humidity curve can be used to calculate inter-diffusivity of water in polyamide active layers. By combining the measurements of water mass …

Structural effects of chloraminated seawater on the SW30HR reverse osmosis membrane
… osmosis (RO) membranes, react with the polymeric active layer and affect membrane performance as a result. This work investigates structural and performance changes to the SW30HR RO membrane exposed to seawater disinfected with monochloramine. Batch experiments with RO membranes were conducted to …

Investigating the adsorption and transport of water in MFI zeolite pores for water desalination
… diffusive transport of water across a non-porous polyamide active layer. Alternatively, fabricating a microporous active layer capable of rejecting salt ions while allowing for water transport would increase the permeability while maintaining high salt rejection. Zeolites provide a model porous …

Chemistry and Measurement at Aqueous Nanoscale Interfaces
… formed. The second describes the synthesis of polyamide membrane active layers using a support-free approach and examines the effect of monomer concentration on the morphology, water sorption, longitudinal elastic constant, and thermal transport properties of the film. Although these two areas …
