This paper discusses the long-term operation of a UF membrane system for drinking water treatment under 'passive' (i.e. without backwash, chemical cleaning and permeate pumping) conditions could be sustained over extended periods. Without any sparging, a steady state permeate flux of approximately 2 Lm-2hr-1 could be maintained. Providing infrequen...

Our work explores how drinking water membranes age over the long-term in operational settings. By partnering with water treatment plants and monitoring their membranes over several years, the performance of membranes has been linked to their haracteristics and operation. In this presentation, performance benchmarks among membranes are identified a...
