What is Ultra-filtration (UF) System

Ultra-filtration (UF) is the purification and separation of solutions through semi-permeable membranes using forces such as pressure or concentration gradients. Ultra-filtration membranes allow only water molecules, inorganic salts, and small organic molecules in the solution to pass through, removing 90-100% of pathogens, organic molecules, viruses, etc., thus achieving the purpose of water purification.

Ultrafiltration technology is now widely used as pretreatment before reverse osmosis , water reuse, drinking water treatment, and other fields. Regardless of the source water quality, the system can produce stable water quality at a low cost.

How do Ultrafiltration Membranes Work?

Ultrafiltration (UF) is a type of physical filtration that works by forcing water through a semi-permeable membrane by external pressure.UF membranes are microporous filtration membranes with consistent pore size specifications and a rated pore size range of 0.01 microns or less. It effectively removes turbidity, particulates, bacteria, and pathogens, allowing only water molecules to pass through.

Ultrafiltration membranes require periodic maintenance cleaning to prevent contamination by solids, scaling, and microbial agents such as microbes and algae.

Ultrafiltration System VS Reverse Osmosis?

UF (Ultrafiltration) and RO (Reverse Osmosis) technology both use the principle of membrane filtration, using ultrafiltration membrane and reverse osmosis membrane as the core filtration device, the main difference between the two is the difference in the size of the filter pores, and that is, the difference in filtration accuracy.

Ultrafiltration membrane made of hollow fiber, pore size between 0.01 to 0.1 micron, can filter out solids/particles as small as 0.02 micron, including bacteria, macromolecular impurities, microorganisms, colloids, etc., but can not remove dissolved minerals, TDS, etc. in the water. Compared to RO systems, UF systems are less capable of desalination, and filtered water can be used to make mineral water, etc.

The pore size of the RO membrane is very fine, about 0.0001 microns, which can filter almost all ions except water molecules, including heavy metals. The desalination effect is good, and the output water is pure water, so the quality of the produced water is relatively higher. Reverse osmosis – generally used for deep water treatment, making pure water, high purity water systems.

The ultrafiltration system can filter the most solid particles in the fluid, but it cannot filter out the dissolved particles like the reverse osmosis system. However, ultrafiltration systems can filter smaller particles than microfiltration or standard carbon filters.

Ultrafiltration System VS Reverse Osmosis
Ultrafiltration System VS Reverse Osmosis


Ultrafiltration systems retain healthy minerals, remove microscopic contaminants, can operate at low pressure, have lower operating costs, and are environmentally friendly and energy efficient. But produced water does not ensure that all viruses and dissolved ions are removed.

RO water purifiers provide a higher degree of purification and produce safer purer water. And the semi-permeable membrane lasts longer than the UF membrane. But it cannot operate at low water pressure, and the filtration process removes some beneficial trace elements, including sodium, magnesium, and calcium.

If your needs are simply to remove solid molecules from the water while retaining healthy mineral ions in the water, ultrafiltration would be an excellent choice for you.

Why Should I Choose UF System Water Treatment?

UF equipment can be used as a pretreatment stage for reverse osmosis treatment. Water treated by an ultrafiltration system and then passed through an RO system reduces damage to the reverse osmosis membrane when treating high sludge density index (SDI) water and extends the life of the system.

Ultrafiltration systems require only low investment and operating costs and minimal need for chemicals or other additives, reducing environmental contamination.
