Abstract
Biological fouling (bio-fouling) is one the main troubles in water desalination and wastewater treatment by membrane processes. In the present study, bio-fouling control approach by surface modification of thin film composite (TFC) membrane with nanosilver coating has been investigated. In order to determine the effectiveness of nanosilver coating, various concentrations of sodium chloride and soft drink wastewater was tested by modified and unmodified membranes. The results showed that the water permeability was improved at least as much as 11.5% for the modified membrane in desalination process. Moreover, the modified membrane (MM) rejection ability towards NaCl was excellent compared to the unmodified membrane (Un-MM). Finally, the stability of MM and Un-MM against bio-fouling effects was investigated by wastewater treatment. The results implied that the antibiological fouling intensity of the MM was higher than Un-MM.
