This slide presentation outlines information on an innovative, spiral wound (UF) ultrafiltration membrane that has demonstrated, via operating results, that the spiral format can now be successfully applied to the full spectrum of microfiltration (MF) and ultrafiltration applications. Topics covered include: historical perspective of reverse osmosis (RO) and UF membrane formats; key features of the spiral including structural integrity and discreet feed channel; spiral innovation; SpiraSep; SpiraSep backflush, air scour, immersed/suction operation, membrane element; International Aquatech Innovation Award; revolutionary performance including membrane chemistry and element configuration; comparison of SpiraSep and RO Spiral Membrane Operation; operating data including canal water; secondary clarified municipal wastewater; landfill leachate; pre-sand filter FeCl₂ coagulation; and, applications. Includes figures.
