I.  Hollow fiber membrane water filter

Ultra-Filtration (UF) is a kind of Hollow fiber membrane water filter method. It is a filtration process which utilizes trans-membrane pressure differential to separate particles according to molecular weights.

 
By using hollow fibers UF membrane as filtration media, raw water particles which are smaller than "Pore" of UF membrane will permeate through and collected as permeate; whilst, particles which are larger than UF membrane pore size will be separated as concentrate under certain pressure applied.

UF membrane is an asymmetric semi-permeable membrane made of high molecular material by special technology. Its' hollow fiber tube cover densely by micro-pores which allow solution flowing in or out the membrane under the influence of pressure. UF membrane pore size range from 0.1 to 0.005 μm or molecular weight (200,000 to 10,000 Daltons) for different applications.

Generally, it is used to remove high molecular-weight substances, colloidal materials, and bacteria, organic and inorganic polymeric molecules.

II. UF Ultra Filtration System 

UF Ultra Filtration System is formed on the basis of membrane separation technology to remove particles by factors of pressure driven process, cross flow design and particle sizes. Feed solution is driven to flow from high osmotic pressure region to low osmotic pressure region. Particles in feed liquid above 0.01 m of membrane...... pore sizes will be refrained to pass through the membrane and flowing over it to produce concentrate. Low molecular weight solutes and components will be passing through the membrane by osmotic pressure driven force and collected into purifying compartment as permeate water. The process contributes to separate feed water into purity water and concentration.

III. Advantages

A proprietary alloy is mixed with PAN material in a unique production process to create special element construction of the U-FLOW® UF membrane, which shows better support and physical characteristics comparing the other matericals.

1. Greater Hydrophilic, better biofouling resistance, higher flux by 30%.

2. Doubled pressure tolerance than other UF products.

3. Finer pore size and closer pore distance for higher porosity to enhance effectiveness of filtration.

4. U-FLOW® UF membrane structures give better biofouling resistance for longer membrane service life.

5. Dry finished membrane will have the benefits of lengthened storage duration, easy transportation, and free from toxic

Chemical residuals from membrane preservation by mixed solution of glycerin and formaldehyde.

6. Optimum storage temperature between -20ºC~45ºC is recommended.
