Toelichting (Engels) A diffusion-convection controlled mass transfer model was developed for predicting the retention behaviour of full-scale nanofiltration (NF) plants. The model is based upon a previous diffusion-only-controlled transport model and is described by an analytical equation in which the retention can be calculated as a function of the recovery. The three main parameters in the model are Kw, Ks, and Kc, respectively, the water transfer coefficient, solute transfer coefficient and the convective hindrance factor. These parameters can be determined experimentally for a given membrane and solute or can be taken from the literature for a given membrane and solute. Both laboratory-scale and bench-scale NF experiments were carried out with several trace organic contaminants using TriSep TS80 NF membranes

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
