Impact of membrane ageing caused by chemical cleaning on the removal of trace organic contaminants by nanofiltration

Journal Article


Abstract


  • Fouling is an inevitable phenomenon when using nanofiltration (NF) membranes in water

    treatment applications which necessitates periodic chemical cleaning to restore the permeate

    flux. However, harsh cleaning chemicals and conditions (i.e. high cleaning temperature) may

    accelerate membrane ageing, and cause variation in membrane surface properties and

    separation efficiency. Indeed, some evidence has emerged that chemical cleaning may lead to

    considerable variation in the retention of inorganic salts as well as some trace organic

    contaminants of concern (Simon et al. 2009; Simon et al. 2012).
