Ultrafiltration is an excellent membrane technology for removing very fine particles, microorganisms and organics as small as 1000 molecular weight. Ultrafiltration is used for a pretreatment for reverse osmosis, as a oil/water separator, to remove organic contaminants and to provide high quality filtration for industrial applications. UF is a low pressure (5 - 150 psig) process for separating larger size solutes from aqueous solutions by means of a semi-permeable membrane.
