Simplified analysis of contaminant rejection during ground- and surface water nanofiltration under the information collection rule

摘要

a simple, closed-form analytical expression based on the homogenous solution diffusion model is derived for contaminant removal during nanofiltration (NF) of ground and surface water. Solute permeation and back-diffusion coefficients were used as fitting parameters to model rejection characteristics of four thin-film composite NF membranes under condition typical of drinking water NF.
