Ultrafiltration system Description: 

Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. A semipermeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline.

Ultrafiltration uses hollow fibers of membrane material and the feed water flows either inside the shell, or in the lumen of the fibers. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains. When strategically combined with other purification technologies in a complete water system, UF is ideal for the removal of colloids, proteins, bacteria, pyrogens, proteins, and macromolecules larger than the membrane pore size from water. The primary removal mechanism is size exclusion, though surface chemistry of the particles or the membrane may affect the purification efficiency. UF can be used as pretreatment for reverse osmosis systems or as a final filtration stage for deionized water.

UF Ultra Filtration System 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.
