The spiral wound membrane has proven to be the most efficient format for dissolved solids filtration (reverse osmosis), however, the absence of a backflush capability has prevented it from participating in the larger suspended solids filtration (microfiltration and ultrafiltration) market. To enable the spiral to function successfully as a suspended solids filter, a spiral wound ultrafiltration membrane has been developed that combines the spiral's superior performance with backflush capability. A specially formulated hydrophilic membrane resists fouling and delamination. Spiral wound construction allows the membrane to perform filtration duties only, there is no structural component requirement imposed on it. The feed channel provides an efficient and effective air scour and a clear path for feedwater and suspended solids. Fouling is further minimized and high flux rates are maintained by a combination of immersed / suction driven operation and chemical regimes.
