The incorporation of ultrafiltration has become increasingly prevalent in drinking water treatment. However, limited data exists regarding the impacts of membrane ageing over extended periods of full-scale operation. The present study examined performance factors (clean membrane resistance, fouling rate, and susceptibility to breach), as well as characteristics (presence of hydrophilic additive (HA) present in membranes) for polyvinylidene fluoride membranes that are widely employed. Clean membrane resistance remained constant over time, whereas the fouling rate decreased with age. Surface and bulk HA content were observed to decrease with age. However, poor correlations were observed between HA content and clean membrane resistance. Results suggest that although a reduction of HA occurs as membranes age, membranes continued to provide good treatment performance until they reached a certain level of HA content reduction that was site-specific. Overall, these findings provide important insights regarding the mechanisms associated with membrane ageing.

This book analyses the sustainability of membrane operations applied on an industrial scale, as well as that of those under investigation on lab/pilot scales, covering also the preparation of both polymeric and inorganic membranes. It presents reverse osmosis in desalination, membrane bioreactors for municipal wastewater treatment and pressure-driven industrial wastewater treatment in agrofood and textile fields as examples of industrial membrane operations. Regarding the membrane processes still on a lab/pilot scale, the analysis includes membrane operations for the recovery of valuable products from wastewater streams, for the removal of toxic compounds from water/wastewater, and for zero liquid discharge approaches in desalination. The book offers a useful guide for scientists and engineers working in various fields, including membrane technology, separation, desalination, and wastewater treatment. Alberto Figoli and Alessandra Criscuoli are both Senior Researchers at the Institute on Membrane Technology (ITM-CNR), Italy.
