Ultrafiltration (UF) is a membrane process used to remove suspended solids, colloidal matter, high molecular-weight substances, and bacteria and viruses from various feed water sources. UF membranes can achieve a low and consistent silt density index (SDI) and are often used as pretreatment for reverse osmosis using surface water, seawater and biologically treated wastewater as feed source.

UF membranes incorporate high-strength, hollow fibers that deliver superior performance without the risk of fiber breaks. UF membranes are available in inside-out and outside-in flow configuration. Both types of membranes have excellent low fouling characteristics. These hollow fiber membranes operate under a pressurized flow configuration for superior performance.

hollow fiber UF membranes offer reliable removal of turbidity, microorganisms, and viruses. Turbidity can be reduced to less than 0.1 NTU. Typically, a 6-log removal for bacteria, giardia and cryptosporidium, while a 4-log removal for viruses, can be achieved.

The fibers in the module are held firmly in place, which reduces the stress on the fibers even at high flow velocities. Uniform fiber packing limits the pressure drop variation within the module and prevents localized high fouling conditions. The unique end cap sealing design allows for high pressure operation and ease of assembly. UF modules can be used as dead-end filtration or in cross flow mode.

The UF Membrane inside-out modules contain an advanced UF fiber made from a modified polyether sulfone (PES) material. The fiber is prepared by a patented cloud point precipitation method. This method ensures a very uniform pore size distribution and high pore density in the membrane. As a result, the product water quality from the modules is significantly better than the quality from conventional UF modules at a very low operating pressure. The membranes are available with 0.8 mm ID fibers, suitable for feed water turbidity up to 30 NTU.

The UF Membrane outside-in hollow fiber ultrafiltration modules contain polyvinylidene fluoride PVDF membranes manufactured by innovative modified thermally induced phase separation (TIPS) method. The membrane has high mechanical strength, high chemical and chlorine tolerance, and ability to handle high feed turbidity with wide range of application. The membranes are available with 1.25 mm (0.05 inch) OD fibers to treat feed water with high turbidity up to 300 NTU.

As with most conventional filtration methods, sand filters and media filtration require consistent raw water quality to deliver quality effluent, which is not always possible. They also don't provide an absolute barrier. Traditional media filters typically remove particles to down to about 5 microns.

Ultrafiltration (UF), however, does not suffer from those limitations. This technology uses an ultrafiltration membrane barrier to exclude particles 0.02 to 0.05 microns, including bacteria, viruses, and colloids, meeting increasingly stringent water-quality standards around the world, and providing a stable, reliable, and consistent water quality.

UF offers:

  • High and consistent product quality measured by turbidity (NTU) or silt density index (SDI).
  • Tolerance to feedwater quality upsets.
  • No use of pretreatment chemicals (polymer, coagulant, pH adjustment) and associated costs for sludge disposal.
  • Small footprint and less weight than media filters.

When used as a pretreatment for reverse osmosis (RO) , UF also helps reduce fouling of the RO membranes, which can lead to:

  • Reduced chemical cleaning frequency and consequently, lower operating costs and downtime.
  • The potential to operate RO at higher flux, with fewer membranes and vessels — leading to lower capital cost for the RO system.
