Resumen: | Chlorophenols, commonly found in the wastewaters of numerous industries, are widely considered as priority pollutants and their persistence may cause severe environmental problems. Among the methods described for their removal, pressure-driven membrane processes are considered as a reliable alternative. In this paper we study the influence of different operational variables (applied pressure, feed concentration and pH) on the removal of 4-chlorophenol from synthetic aqueous solutions by nanofiltration using three different polyamide membranes (NF-97, NF-99 and RO98pHt). The Spiegler-Kedem-Kachalsky model was applied to predict the nanofiltration removal process. Model constants for the three membranes were obtained and there was good agreement between the experimental and model rejection data. |
