Ultra-filteration (UF)

Enquiry Form

WHAT IS ULTRAFILTRATION ?

Ultrafiltration is a variety of membrane filtration in which forces like pressure or concentration gradient lead to a seperation tru a semi-permeable membrane.

Suspended solids or solutes of higher molecular weight are retained in the retentate while water and low molecular weight solutes pass through the membrane in the permeate ( filterate ).

This seperation process is used in industry and research for purifying and concentrating macromolecular ( 10 *3 - 10* 10 Da ) solutions especially protein solutions. Hence this process if of a big usage in dairy industry.

UF membranes are defined by Molecular weight cut off (MWCO).

ADVANTAGES OF ULTRAFILTRATION

The advantage of UF lies in their flexibility. It can be adapted to all sizes of installations and can be used alone or as an addition to other treatment technologies.

  1.  
    • 1. UF systems can be used both for pretreatment and post treatment of water.
    • 2. UF Plants are made available for different outputs ( LPH ).
    • 3. These work on cross flow filtration principle and are designed to achieve around 85% recoveries by separating fine physical particulates like SDI, suspended solids or Colloidal silica that are harmful to RO membranes.
    • 4. In DM Plants, these are used after the water treatment to control organic and microbial impurity.
    • 5. As an advanced technology used for removal of microbial count.

APPLICATION OF ULTRAFILTRATION

DRINKING WATER

elimination of micro organisms like

  • algae
  • bacteria
  • virus
  • parasites
  • e -coli
  • giardia

INDUSTRIAL PROCESS WATER

  • industries like electronics , pharma , cosmetic , food and bottling industries.
  • pretreatment of demineralized water, purified and boiler water
  • removal of particulates and micro organisms
  • controlled encrustation

POOL WATER

  • total elimination of germs , cysts , e coli , viruses etc
  • guarantees the sanitary safety and comfort of swimmers

RECYCLING
