Grey Water Recycling and Reuse

Ultrafiltration PlantUltrafiltration is a filtration method similar to reverse osmosis, the main difference being in the size of the particles ultrafiltration membranes retain.
UF (Ultrafiltration) typically implements hollow fibre membrane material made from PVDF polymer. UF membranes are more tolerant to chemicals and temperatures of up to 40ºC. As the feed water passes either side of the membrane, low molecular weight molecules pass through the membrane, while high molecular weight molecules are retained.

When used as part of a complete water filtration process UF can be utilised for the removal of proteins, colloids, bacteria and any molecules larger than the membrane pore size. UF membrane pore sizes typically range from 0.005 microns to 0.1 microns.

Ultrafiltration can also be used as a pre filtration method for Reverse Osmosis, this reduces membrane fouling of the RO plant.
Ultrafiltration is typically used in :

  • Wastewater Treatment
  • Dialysis
  • Desalination
  • Water Recycling
  • Sterile filtration
  • Drinking Water Treatment
  • Swimming Pool Water

Depending of the quality of the incoming raw water feed additional filtration methods may be required prior to Ultrafiltration.

Such treatment methods include :

  • Flocculation
  • Precipitation
  • Disc Filtration

Ultrafiltration and Water Recycling

Ultrafiltration can be implemented within industries that use or discharge large volumes of water.

Typical industries include :

  • Chemical Plants
  • Food & Beverage
  • Power Plants
  • Steel Industries
  • Waste Water Treatment Plants
