El tipo de empaque y su característica es uno de los factores que influyen en la hidrodinámica de la columna. En los procesos de adsorción en ocasiones resulta técnica y económicamente ventajosa la operación en columna comparado con sistemas a

Fouling in ultrafiltration was modelled in terms of dimensionless correlations and the Sherwood number using a polyethylene glycol aqueous solution. The rheological nature of this solution was dilatant. Tubular ceramic membranes of 35 kDa molecular w

In this work Hermia's models adapted to crossflow ultrafiltration were used to investigate the fouling mechanisms involved in the ultrafiltration of polyethylene glycol (PEG). Although PEG has been very often used as a standard macromolecule in ultra

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 gly

In this work Hermia's models [J. Hermia, Constant pressure blocking filtration laws—application to power-law non-newtonian fluids, Trans. Inst. Chem. Eng. 60 (1982) 183–187] were used to investigate the fouling mechanisms involved in the ultrafil

A theoretical model was used for permeate flux decline prediction. Ultrafiltration experiments were performed varying TMP and feed concentration. The feed solution consisted of an aqueous solution of polyethylene glycol with a molecular weight of 35,

Permeate flux decline with time was estimated by means of a model [1] that considers gel layer formation as the main fouling mechanism. Several experiments were performed with two different membranes. Both of them were monotubular ceramic membranes.

The aim of this work was to validate the dynamic model for the average permeate flux that considers membrane fouling as a dynamic process from non-equilibrium to equilibrium to predict permeate flux decline with time in the ultrafiltration of macromo

The purpose of this work was to compare the experimental results on flux decline with time in the ultrafiltration of macromolecules with the results predicted by a model based in the resistance in series model. The model considers the osmotic pressur

In this paper a shear-induced diffusion model is used to predict permeate flux decline with time in the ultrafiltration of macromolecules. The results estimated by the model were compared with the experimental results obtained in a pilot plant. Tubul
