UF Membrane

Ultrafiltration Membrane Filtration

Ultrafiltration technology(UF) is a kind of nano-scale membrane pure physical separation technology. The hollow fiber ultrafiltration process uses hollow fiber membrane filaments as the filter medium, uses the pressure difference between the inside and outside of the membrane filaments as the driving force, and measures different physical diameters in the solution according to a certain filter aperture. The process of separating large and small substances to achieve the purpose of purification, separation, purification and concentration of the solution. Ultrafiltration membrane filtration can have extremely high fluxes but in most practical applications the flux varies between 50 and 200 GFD at an operating pressure of about 50 psig in contrast, reverse osmosis membranes only produce between 10 to 30 GFD at 200 to 400 psi.

When is Ultrafiltration Membrane Filtration used

The distinction in pore size and types of particles removed means each type of filtration serves a unique purpose.

Ultrafiltration is the filtration method of choice for people who prefer minerals left in their water but still want microscopic contaminants taken out. A UF system may be selected over an RO system because it wastes less water to the drain. For example, we have clients someone may choose UF in California where water use is regulated. someone in South Carolina, where the water has few dissolved minerals to begin with, may choose UF since RO wouldn’t be necessary. Sometimes, Ultrafiltration membrane filtration is used to recycle effluent water after filtration, so the water can be reused for irrigation.

Reverse osmosis is used in situations where all particles including dissolved substance must be stripped from the water. Some people prefer RO water from their refrigerator or tap, especially if they’re on well water supply. RO is also favored for saltwater aquariums, where an exact amount of salt can be added back to the clear water. Nanofiltration is frequently used to remove heavy solids in dairy and for some softening purposes. Microfiltration removes suspended solids like algae and sediment.

Ultrafiltration Membrane Filtration



Meeting the global drinking water quality standards requires a wide local variety of treatment methods, due to different feedwater sources. Pentair delivers solutions for every drinking water application.

Ultrafiltration nembrane filtration is the perfect method for producing drinking water from surface water.

Ground water from a variety of sources, such as ground water, surface water, lake or river water or seawater can be sources for potable water treatment.

In some cases, bore holes for collection of ground water that were constructed many decades ago are constructed of bricks. When exposed to ground movement, cracks can develop which allows surface water to enter the bore holes.

The traditionally clean ground water can then become contaminated with microorganisms. This is referred to as “ground water under the influence of surface water”.

Brother Filtration membrane solutions can be used to filter the ground water to remove contaminants and guarantee complete removal of bacteria and viruses. Surface water contains microbiology as well as suspended solids. Sometimes dissolved organics are present that cause color in the surface water. Contact us now for more UF membrane information.
