What is ultra filtration treatment plant?

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.

What are the benefits of ultra filtration treatment plant?

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.

  • Low Cost (Minimum pumping energy required, thus energy saving)
  • Saves you money and Removal of Bacteria and Viruses
  • Easy to operate & maintenance (Chemical resistance, wide PH ranges, back-washable
  • No contaminant residue caused by chemical reaction
  • Capacity 80 LPH to 50,000 LPH and Recovery ratio up to 98%

What Can Affect the Performance of Ultrafiltration Water System?

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

  • Permeate rate is directly proportional to the velocity of the flow across the surface of the membrane. This parameter is further critical in case of high viscosity liquids such as suspensions and emulsions. As the flow increases, more pumping energy is required. Hence, it is important that the velocity shouldn’t go beyond the optimum limits as it results in loss of efficiency. It can be achieved by calculating the right ratio between the pump energy and permeate rate.
  • Pressure across the membrane surface also affects the permeate rate. In ultrafiltration membrane modules using capillary technology, the operating pressure has to be kept low because of structural limitation. Very high pressure causes compaction and fouling.
  • Temperature also plays an important role in deciding the performance of ultrafiltration system. Usually, permeate rate increases with the increase in the temperature. However, the correlation has to be studied before reaching to a conclusion.
