... and a flux of 40 l/h/m2 was found to keep the mass transfer coefficient within a tolerable range for all PEGs used. Keywords: Ultrafiltration; Characterisation; Pore size; Distribution 1. Introduction The cut-off of a membrane can be determined from the permeation of dilute solutions containin ...

... presence of calcium chloride due to the more efficient retention of the bivalent calcium. Keywords: Membranes; Nanofiltration; Salt rejection; Characterisation 1. Introduction While nanofiltration (NF) is a relatively new membrane process, it is already widely used for water treatment in differen ...

... retention curve obtained with a mixture of dextran molecules in predicting rejection of other isolated solutes. This result suggests that a characterisation method using monodisperse tracer molecules instead of polydisperse ones would be more adequate to predict rejection based on size exclusion.
