Superior to sand filters and traditional media filtration

What Is Ultrafiltration Membrane?

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)membrane, however, does not suffer from those limitations. This technology uses an ultrafiltration membrane barrier to exclude particles 0.02 to 0.5 microns, including bacteria, viruses, colloids, micro organisms such as cryptosporidium and giardia, as well as silt, turbidity. Meeting increasingly stringent water-quality standards around the world, and providing a stable, reliable, and consistent water quality.

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.

Ultrafiltration Membrane Advantages

  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.

How Ultrafiltration Membrane Works?

Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane element. In this method we use Maxie hollow fibers.

UF is a barrier to suspended solids, bacteria, viruses, endotoxins, and other pathogens. UF produce water with very high purity and low SDI.

A pressure is the driving force for the membrane. The pressure allows the water to flow through the pores of the membrane. All matter larger than the pores is retained on the surface of the membrane. This process is called pore size exclusion. The membrane is called semi-permeability because it allows water to pass while it retains other substances. The pore size of the membrane determines the size of the particles that are being removed. If the pores are micrometer sized the membrane is called a microfiltration membrane, if the pores are smaller than a tenth of a micrometer the membrane us called an ultrafiltration membrane.


Microfiltration and Ultrafiltration membrane elements are capable of removing suspended solids, bacteria and larger micro organisms, such as cryptosporidium and giardia. Additionally the ultrafiltration pore size is small enough to reliably remove smaller matter such as viruses, macro molecules and colloidal matter. Dissolved matter, such as e.g. beneficial minerals are not being retained by the membrane elements.

Drinking Water From Surface Water

Water from a variety of sources, such as ground water, lake water, river water or seawater can be sources for drinkable water treatment.

Meeting the global drinking water quality standards requires a wide local variety of treatment methods, due to different feedwater sources. Maxie delivers solutions for every drinking water application.
Ultrafiltration is the perfect method for producing drinking water from surface water.

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 microbes. This is referred to as “ground water under the influence of surface water”.

The Maxie 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. Maxie membranes solutions can provide a reliable treatment system that eliminates the need for multiple treatment steps.

Ultrafiltration Membrane FAQ

  • Q What is ultrafiltration membrane?

    MAXIE standard ultrafiltration membrane is made of high quality polysulfone membrane with high molecular polymerization. It is also called UF membrane filter. Best seller for ultrafiltration membrane is pore size 0.05 microns. 
    UF membrane filter works well to retain viruses, bacteria, pathogens, turbidity, and suspended matter,  while letting water, and beneficial minerals get through. It is a safe, high-flow membrane material
  • Q What is 0.1 micron water filter?

    Micron water filter membrane is a kind of polysulfone material molecular sieve. 1 micron is one thousandth of a millimeter.
    Maxie microfiltration membrane is made of high quality polysulfone material with a pore size of 0.1 micron. Bacteria are between 0.5 ~ 5 microns in size. 
    Micron water filter membrane helps to remove bacteria, pathogens, suspended solids, eggs and spores. Not only to ensure large flow, but also to avoid the generation of waste water.
  • Q What is PVDF filter cartridge?

    PVDF filter cartridge is a kind of Polyvinylidene fluoride material molecular sieve. PVDF UF membrane has high strength, acid and alkali resistance. The initial flow can be restored by hand scrubbing.
    Maxie PVDF filter cartridge is made of high quality Polyvinylidene fluoride material with a pore size ranges from 0.01 ~ 0.1 micron. Bacteria are between 0.5 ~ 5 microns in size. 
    PVDF filter cartridge helps to remove bacteria, pathogens, suspended solids, eggs and spores. PVDF hollow fiber membrane is not easy to damage, and its service life is more than 10 times that of ordinary ultrafiltration membrane.
  • Q Are ultrafiltration membrane permanent?

    No, The polysulfone ultrafiltration membrane can be used for 1-3 years depending on the water quality and water consumption. Contaminated water will shorten the service life of the hollow fiber uf membrane.
    PVDF UF membrane can be used for more than 10 years, due to the acid and alkaline resistance of its material, and high strength. It can withstand polluted water without damaging the stability of the membrane. And when used for a period of time, the flow can be recovered by manually scrubbing. Under the same conditions, the service life of PVDF is more than 10 times that of polyethersulfone ultrafiltration membrane.
  • Q What is gravity water filter?

    Gravity water filter is made of polysulfone ultrafiltration membrane. Water can pass through hollow fiber membranes under natural gravity.
    This polysulfone ultrafiltration membrane has the characteristics of large flow rate and strong hydrophilicity.
