Ultrafiltration (UF) has been widely applied in the area of potable water production as abarrier to pathogens and viruses, and for pretreatment of surface water and biologicallytreated municipal effluent before Reverse Osmosis (RO) systems. UF is also now beingconsidered as pretreatment to Sea Water Reverse Osmosis (SWRO) plants. UF providesa very high quality, low SDI (Silt Density Index) product, regardless of the incomingseawater quality, and offers a pretreatment alternative with a small footprint and lowchemical consumption. These benefits of UF make it an excellent choice for SWROpretreatment in some situations. However, many SWRO systems operate very well withconventional pretreatment, so UF is not always justified over conventional pre-treatment.This paper usees data from pilot studies and full-scale operating plants to discussalternatives for SWRO pretreatment and factors that should be taken into account whenselecting the pretreatment technology. Includes 10 references, table, figures.
