Separation of dimethyl phenol using a spiral-wound RO membrane — Experimental and parameter estimation studies
... compound, namely dimethyl phenol, using a polyamide membrane was investigated in this study. Experiments were conducted on a laboratory-scale spiral-wound RO module. The permeate concentrations and rejection coefficient values were measured for various transmembrane pressures and fee ...

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 ...

The effect of the ladder-type spacers configuration in NF spiralwound modules on the concentration boundary layers disruption
The laminar flow structure and concentration distribution in a narrow rectangular channel simulating the feed channel of nanofiltration (NF) spiral-wound modules are investigated. The continuity, Navier–Stokes equations and the solute continuity equation are solved by the control volum ...
