Membrane Filtration Systems

SHARE

Membrane systems serve for treatment of sea water, brackish water, drinking and distilled water. Applications: in the petrochemical industry [waste water disposal, back use of technological water], pharmaceutical industry [infusion solutions, production of medicines] and food processing industry [water for production of drinks, processing of fruit and vegetable juices, milk processing] and also during water treatment in water management plants, power stations and thermal plants [demineralised cooling water, additional water for feeding of boilers].

All the membrane systems include high-pressure membranes, high-pressure pumps, an embedded regulator and necessary pre-treatment.

 

Membrane filtration is a physical process at which a semi-permeable membrane is used for separation and removal of soluble substances, organic colloid substances, viruses and bacteria from water.

At present there are used four types of membrane filtrations according to the size of the impurities to be removed:

  • Microfiltration
  • Ultrafiltration
  • Nanofiltration
  • Hyperfiltration [reverse osmosis]
