What Is Ultrafiltration

Ultrafiltration (UF) is a single-membrane water filtration method that acts as a barrier to viruses, particulates, bacteria, endotoxins, and other microbes suspended in the water. This purification method allows for the production of pure water with a low silt density. Ultrafiltration membrane filtration (UF) is a low-pressure membrane filtration procedure for water treatment that removes turbidity-causing particles like suspended solids, germs, colloidal debris, and proteins.

What is the process employed?

UF, in particular, employs a semi-permeable membrane that is well-known. This semi-permeable membrane enables UF to easily repel infective chemicals, bacteria, particles, and organic components, resulting in the production of drinkable water.

Ultrafiltration’s primary goal is to remove contaminants that affect water’s color, taste, and odor. Using the Ultrafiltration membrane, particle debris that degrades water quality can be removed instantaneously.

Size exclusion or sieving is the basic separation process of UF membrane filtration, and the graphic shows that UF successfully eliminates particles in the size range of less than 0.01 to 0.1 mm. When these contaminants are effectively removed from a source water, a filtrate is produced that is ideally suited for downstream reverse osmosis treatment (RO).

What is the use of ultra-filtration and advantages?

Ultrafiltration is used in chemical and pharmaceutical manufacturing, Beverage and food processing, and waste water treatment to recycle flow or later add value to products. Ultrafiltration is also used in dialysis of blood.

1. Drinking Water

To make water potable, drinking water ultrafiltration can be used to remove particles and macromolecules from raw water. It’s been utilized to either replace current secondary (coagulation, flocculation, sedimentation) and tertiary (sand filtration and chlorination) filtering systems in water treatment plants, or as independent systems in remote areas with expanding populations. When treating water with high suspended particles, UF is frequently used as a pre-treatment stage, with primary (screening, flotation, and filtration) and certain secondary treatments.

2. Concentration of proteins

UF is widely utilized in the dairy sector, particularly in the production of whey protein concentrate (WPC) and lactose-rich permeate from cheese whey. A UF method can concentrate whey 10–30 times the feed in a single step.

Advantages of Ultrafiltration System

1: Zero Power Requirement:

The Ultrafiltration System operates without the use of electricity. Water can be filtered using natural pressure with this technique. Choose a zero-power water purifying procedure instead of worrying about power outages or paying electricity costs.

2: Viruses and bacteria are eliminated

By pushing water through a membrane, ultrafiltration eliminates particle materials. As a result, it not only kills all bacteria and viruses, but also eliminates their eggs from the water, ensuring that the water is clean and safe.

3: Deep cleaning

Even dirty muddy water may be purified with the Deep Cleaning Ultrafiltration System. In comparison to conventional filtration systems, it can readily remove all solid particle matter and germs from filthy water. The ultrafiltration membrane can quickly cleanse even the dirtiest water, making it safe to drink.

4: Ensures the purest kind of drinking water

The Ultrafiltration System will always generate safe drinking water. Because the ultrafiltration membrane is extremely robust, no small or large particle matter can flow through it.

5: System with Low Maintenance and High Performance

Water purifiers that use the Ultrafiltration System don’t need to go through a long-term maintenance routine and can last for many years. The manual flushing device in these purifiers removes all of the trapped germs and muck, ensuring that the purifier operates at peak performance for at least eleven years.

6: Excellent Purification

Most water filtration systems, with the exception of the Ultrafiltration system, use chlorine treatment to kill and extract microorganisms from the water. However, the eggs (cysts) cannot be removed with this procedure. The Ultrafiltration System, on the other hand, removes the chlorine-resistant eggs (Cysts) of gastrointestinal parasites such as cryptosporidiosis, giardiasis, and amoebic illness, resulting in pure drinkable water.


Ultrafiltration (UF) is a water purification process in which water is forced through a semipermeable membrane. Suspended solids and high-molecular-weight solutes remain on one side of the membrane, the retentate side, while water and low-molecular-weight solutes filter through the membrane to the permeate side.

UF can remove most organic molecules and viruses, as well as a range of salts. It has gained popularity because it produces a stable water quality no matter the source water, has a compact physical footprint, removes 90-100% of pathogens, and does not require chemicals, except for cleaning membranes.

UF Membrane Characteristics

The pore size of ultrafiltration membranes ranges from 0.1 to 0.01 microns, but “molecular weight cut-off” (MWCO) is now one of the best ways to describe UF membranes. MWCO is the molecular weight at which 90% of a macromolecular solute does not pass through the membrane. UF’s range of filtration lies between microfiltration and nanofiltration.

The membranes used in ultrafiltration require maintenance cleaning to prevent fouling with solids, scaling, and microbiological agents such as microbes and algae. Separated contaminants condensed in the UF retentate must be disposed of.

Typical UF applications include:

  Treatment and recycling of wastewaterand industrial process water

  Removal of particulates and macromolecules (for example, 90-95% arsenic removal) for potable water production

  Standalone systems

  Augmentation or replacement of secondary and tertiary filtration stages in existing water treatment plants

  Filtration of paper pulp mill effluent

  Food and beverage industryapplications

  Water softening.


  No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment)

  Size-exclusion filtration as opposed to media depth filtration

  Good and constant quality of the treated water in terms of particle and microbial removal

  Process and plant compactness

  Simple automation

  Environmently friendly.
