Ultra Filtration

Ultra Filtration Unit

Ultrafiltration is meant to remove high-molecular weight substances such as colloidal materials, and organic and inorganic polymeric molecules including bacteria, and most viruses. Ultrafiltration uses pressure to separate the particulates from the liquid.  Low applied pressures are sufficient to achieve high flux rates from an ultra filtration membrane.

Ultra Filtration Attributes

  • Low fouling membrane modules
  • Excellent filtration performance with high flux
  • High chemical resistance and temperature tolerance for effective membrane cleaning
  • Very fine nominal pore diameter (0.03 µm)
  • High removal efficiency of bacteria and viruses
  • Dead-end or concentrate bleed flow capabilities
  • Can be periodically back washed and air scoured to improve performance and extend operating life by removing the fouling layer
  • Simple, vertical, modular design allows low cost, compact systems
  • UF Outside-In or Inside-Out Configuration allows for less plugging and higher solids loading, higher flow area and easier cleaning

Ultrafiltration uses a cross-flow separation process.  The feed stream flows tangentially across the membrane surface, the permeate flows out of the stream while the concentrate will get progressively more concentrated as the permeate is removed. The Membrane does not collect particles, it acts as a barrier allowing clean permeate to penetrate and the feed flow to concentrate.  The pore sizes for ultrafiltration membranes range between 0.001 and 0.1 micron. 

Ultrafiltration is ideal for applicationsused in the production of high purity water.
