International Symposium on Membrane Biofouling

Please Note...To obtain slide presentations and other material from this sympoisum, please contact Harry Ridgway. Thank you!

Speaker Change. Due to recent unforseen circumstances, Dr. Gil Dhawan is unable to speak at the symposium. Dr. Dhawan's presentation would have addressed the topic of advances in membrane cleaning technologies. In his place, Professor Phil Stewart, Director of the Center for Biofilm Engineering at Montana State University, will instead speak on fundamental and applied aspects of biofilm control in engineered systems. Professor Stewart's biograph may be viewed HERE. We apologize for any inconvenience this program change might have caused.

Purpose of the Symposium. Water quality requirements have risen steadily in recent decades, not only for drinking water applications, but also for sensitive industrial processes and wastewater discharges. To meet more stringent standards, the utility and industrial sectors have increased reliance upon membrane separations, such as nanofiltration and reverse osmosis. This trend will likely continue as greater levels of water quality and treatment system reliability are sought. Membranes are well positioned to achieve these objectives due to a consistent decline in their real costs resulting from improvements in manufacturing efficiencies, better performance, R&D investment, and supply/demand forces. However, membranes are by virtue of their chemical and structural makeup prone to surface fouling phenomena such as mineral scaling or the adsorption of natural organic matter. Fouling is typically accompanied by significant degradation of membrane performance and lifetime. Biological fouling of membranes (i.e., biofouling) is perhaps the most serious and widely occurring form of fouling, as well as being the least well understood in terms of causation, mechanisms, and remedies.

Brief Description. This intensive two-day symposium will explore in detail the fundamental nature of membrane biofouling and identify effective new strategies for its control (see program outline). To achieve this goal, an international panel of recognized experts in the field of membranes and interfacial processes will be convened (see speaker biographs). The latest scientific and technological advancements will be reviewed with the aim of synthesizing a molecular level framework for describing the causes and management options for membrane biofouling. Emphasis will be placed on how to best integrate fundamental theory and knowledge of membrane biofouling processes with real-world problems in water treatment and purification.
