Ultrafiltration

Product Details:

Ultrafiltration, also known as UF, is a class of filtration that uses a membrane, either in the form of a spiral wound element similar to a reverse osmosis membrane, or more often, a tubular element known as a hollow fiber. Other types of membrane filters are Microfiltration (MF), Nanofiltration (NF), and Reverse Osmosis (RO). These differ primarily in the sizes of particles that are excluded from the filtered water. Ultrafiltration and Microfiltration are size-exclusion processes that reject particles, pathogens, and high molecular weight species. UF has pore sizes in the range of 0.001 to 0.1 micron, with a 0.03 nominal micron rating being typical.

UF is often used as pretreatment to an RO. The UF removes the majority of particulates that fouls an RO, as well as colloids, harmful bacteria, most viruses, and parasites such as cryptosporidium and giardia. The RO removes the remaining bacteria and viruses, dissolved salts, dissolved organics, color, taste, and odor.

UF Benefits to RO Operation

The UF acts as a barrier filter, retaining any particles over 0.1 micron. This allows the RO to operate at a higher design flux and therefore higher total flow, to increase production, or to produce the same flow as before but with less energy. In a new installation, a smaller RO can be used. With UF pretreatment, the RO has reduced requirements for membrane cleaning, meaning that chemical usage and wastewater discharges are reduced. Longer membrane life is also a benefit.

UF Applications

Beverage Water Preparation- UF is used to remove particles, viruses, bacteria, and parasites from city or other source waters used in bottled water or beverage production, usually as feed to an RO.
