Ultrafiltration excels at separating insoluble components from a waste stream, especially oils, precipitated solids, and colloidal particals.

Partially Permeable. Ultrafiltration (UF) is a form of filtration that uses a membrane to separate different fluids or ions. Ultrafiltration will normally separate everything that is not soluble and little or nothing of what is soluble. Ultrafiltration also uses a membrane that is partially permeable to perform the separation, but the membrane's pores are typically much larger than the membranes pores that are used in nanofiltration and reverse osmosis filtration.

Ultrafiltration is most commonly used to separate insoluble components from the aqueous phase. One of the uses that demonstrates the usefulness of ultrafiltration is separation of oil in an emulsion from water. In this case, oil emulsions, for example, machining coolant emulsions can have the oil separated and concentrated, with the water phase being discharged to sanitary sewer, and the concentrated oil phase being disposed of at a lower cost.

Ultrafiltration is capable of concentrating bacteria, some proteins, some dyes, oils and colloidal or emulsified components. Ultrafiltration is only somewhat dependent upon the charge of the particle and is much more driven by the size of the particle.
