Experimental results on permeate flux decline with time obtained from ultrafiltration tests were compared with those predicted by means of Song and Elimelech’s model. Feed solutions consisted of aqueous solutions containing 15 g/L of polyethylene glycol 35 kg/mol. All model parameters were theoretic

The aim of this work was to compare the data on flux decline with time obtained with ultrafiltration experiments of polyethylene glycols (PEGs) performed under different experimental conditions (transmembrane pressures and crossflow velocities) and the theoretical predictions for these experimental

In this work a non-steady state model for cross flow ultrafiltration was tested and the results estimated by the model were compared with those experimentally obtained. Crossflow ultrafiltration experiments were performed in a pilot plant using tubular ZrO2-TiO2 ceramic membranes with a MWCO of 15 k
