UF membranes have pore sizes of approx. 0.005-0.05 micron. They facilitate the removal of molecules with higher molecular weights (e.g. proteins), while allowing dissolved ions and molecules with low molecular weights to pass. This means that conventional UF membranes can capture all microbes and bacteria, and also viruses.
Ultrafiltration has occupied an established position in the drinking water treatment sector. It allows the safe, high-quality conversion of differing types of raw water into drinking water. Moreover, ultrafiltration is steadily gaining in importance in the wastewater treatment sector.
Ultrafiltration is also used as a safe pre-treatment prior to reverse osmosis.
Advantages:
The noted advantages of UF Filtration membranes include:

  • Require minimum pumping energy, thus providing saving on energy
  • Offering chemical resistance over wide PH range
  • Easy to operate & maintain with low investment costs
  • Recovery ratio up to 98%
