What is Ultrafiltration(UF) water filter system?

Ultrafiltration(UF) use hollow filber filter technology. UF membrane pores less than 0.01 microns. It can completely removed rust , bacteria colloidal and other harmful substances of spring water. And keep the trace elements and minerals of spring water. Those element and mineral in spring water are good for human being healt.

UF is most use in mineral or spring water purification. It can produce mineral water or spring water. The mineral or spring bottled water plant is use UF system as the water purification.

Why use UF filter system?

The most filter system in bottled water are RO and UF. RO is removed everything of raw water and produce purified water. But spring water or mineral water is famous for its inside mineral. So that if use RO system, any water can be resource and waste the spring natural funcation. If do not use any filter system. The raw spring water still have some big suspended matter, bacteria colloidal and other harmful substances. So that use Ultrafiltration(UF) filter system.

Ultrafiltration(UF) membrane functions as the core part of the whole system to produce mineral water. Ultrafiltration (UF) membrane serves as a molecular sieve. It separates dissolved molecules by passing a solution through an infinitesimally fine filter. The ultrafilter is a tough, thin, selectively permeable membrane that retains most macromolecules above a certain size, including colloids, microorganisms and pyrogens. Smaller molecules, such as solvents and ionized contaminants, are allowed to pass into the filtrate.

1. Definition of mineral water
Mineral water is water containing minerals or other dissolved substances like calcium, magnesium, sodium, potassium, silica and bicarbonates, which is healthy to drink.

Our water treatment systems are customized and designed to meet the local water conditions and flow rate requirement. The mineral water treatment equipment utilizes a quartz sand filter, active carbon filter, and PP filter for the treatment of raw water. This process not only removes large particles, odor, color, and some bacteria, but protects back-end UF membranes, which helps prolong the life of the equipment.

The ultrafilter is a tough, thin, selectively permeable membrane that retains most macromolecules above a certain size, including colloids, microorganisms and pyrogens. Smaller molecules, such as solvents and ionized contaminants, are allowed to pass into the filtrate. Thus, UF provides retained retentate that is rich in large molecules and a filtrate that contains few, if any, of these molecules.

2. Filter material of Ultrafiltration Water Treatment System 
When choosing filter materials, we offer tailor-made solutions in view of corrosion, pressure, vibration and temperature, as per raw water conditions of customers. For example, if TDS of raw water is too high, fiber glass filter tank will be recommended in order to optimize the whole water treatment system.

3. Advantages of Ultrafiltration Water Treatment System 
1. Mineral water treatment equipment is able to effectively remove most particles, pyrogens, microorganisms, and colloids that are above rated sizes. Some calcium, magnesium, sodium, potassium, silica and bicarbonates are remained in water.
2. It produces high quality water with the least amount of energy.
3. We provide tailor-made mineral water treatment equipment in accordance with raw water condition and your specific requirements.

Ultrafiltration principle

Ultrafiltration is a membrane separation technology, i.e., under a certain pressure,made the small molecules of solute and solvent through certain pore size special membrane,super and macromolecular solute impermeable membrane,left side.
Ultrafiltration principle is a membrane separation process principles, ultrafiltration using a pressure activated membrane, in the external driving force ( pressure ) under the effect of colloidal particles in water interception, and the relatively higher molecular weight material, and water and small solute particles through a membrane separation process. Through the membrane surface of the microporous filtering may be cut-off molecular weight of 3×10000 – 1×10000 material. When the water to be treated by external pressure to flow through the membrane surface, the water molecules and the molecular weight of less than 300 – 500 of the solutes through the membrane, rather than a hole of the membrane microparticles, large molecules such as sieving action are retained, thereby allowing the water to be purified. That is to say, as the water passes through the membrane, the water containing colloidal silica to remove most, at the same time can remove large amounts of organic matter.
