Ultra Filtration Plant or UFP is important process that can separate micro organic molecules and colloids from water with maximum efficiency and effectiveness. The process is used as the pre- treatment to Ion exchange and RO exchange. We have supplied ultrafiltration water systems to a large number of clients who vouch for the superiority of the product. With relatively less pressure requirement than RO system, it is preferred by several applications nowadays.
Our UF plants are build with hollow fiber outside-in membranes, up to 100 m3/h, to purify surface or groundwater from suspended solids, colloids and all kind of micro-organisms such as bacteria, virus, protozoa, germs and larvae.
Ultrafiltration is a separation technique than uses membranes of pore size of .01 to .001 microns. The method is used for removing impurities of high molecular weight. It can remove organic and inorganic polymeric molecules ad colloidal material. However, it is ineffective in removing low molecular weight ions or molecules, e.g. Calcium, sulfate, Sodium and Magnesium Chloride. In this filtration method, the osmotic pressure difference is negligible across the surface if the membrane because the filtration is done for high molecular weight particles. Hence, you don’t need to apply high pressures to achieve high flux rates.
Typically, Ultrafiltration process is similar to Reverse Osmosis. The only thing is, here liquid stream flows along the membrane surface tangentially. Thus two streams are created. The stream that is in the contact of the membrane is known as permeate. Several characteristics affect the rate of permeation such as quality of feed, characteristics of the membrane and the operating conditions. The other stream of liquid is called concentrate stream. It gets concentrated further. In this case, the membrane doesn’t collect ions, but it acts as the barrier to molecules, collides and ions.
In ultrafiltration pre-filtration process by putting conventional filter is not used. The membrane filter has to perform the task of filtering all emulsified as well as suspended particles
