An existing model for the simulation of solvent flux, transmembrane pressure and velocity in spiral-wound modules has been combined with results on the critical flux of spacer filled channels to simulate the colloidal fouling of an RO spiral-wound ...

A model for a spiral-wound reverse osmosis system using the three-parameter membrane transport model by Spiegler–Kedem is presented. The pressure drops in the permeate... to the solution–diffusion model. Since the SK model is known to be the most accurate membrane transport model, the present model for spiral-wound modules may provide more accurate results for design and analysis for reverse osmosis systems. The data generated also show that the pressure drop in th ...

Bench-scale dissolved air flotation (DAF) of Tagus River surface water (Valadas, Portugal) was investigated as pre-treatment for spiral-wound module nanofiltration (SWNF). Before the DAF, a coagulation/flocculation of the surface water was performed using aluminium sulphate, ferri ...
