Abstract:
Heavy metal pollution has become one of the most serious environmental problems today. Nano filtration (NF) has attracted increasing attention over the recent years due to the development of new applications. The present work deals with the application of a thin-film composite polyamide nano filtration membrane for the rejection of chromium ions from synthetic wastewater. In the current work the various operating parameters like feed concentration (10-50 ppm), applied pressure (5-9 kg/cm2), feed flow rate. We observed that the observed rejection of chromium ions increases with increase in the feed pressure because of convection and decreases with increase in feed concentration at constant feed flow rate because of osmotic pressure. The maximum observed rejection of the metal is found to be 97.8% for feed concentration of 10 ppm. The TFC NF300 membrane is characterized by using combined film solution diffusion model. The estimated parameters from model were used to predict the membrane performance and found that the predicted values were in good agreement with the experimental results.
