High Purity Water Production

Certain industries – pharmaceuticals, microelectronics - demand special water quality.

Hidrofilt has over 20 reference units in these industries; possesses the know-how and offers the followings:

  • validated water treatment systems by the application of the state-of-the-arts membrane processes - RO/MC/EDI - , equipments, instruments, controls
  • documentation according to Standards
  • validation / qualification in pharmaceutical industry (IQ, OQ)
  • field-survey
  • high quality after-sales services

 

Pharmaceutical industry

Pharmaceutical industries require different grade of treated water:  Purified Water (PW) or Highly Purified Water (HPW). The specifications for quality are according to pharmacopeias: USP and Ph. Eur.

Microelectronics

This industry requires ion-free water with the highest theoretical purity; conductivity is as low as 0,055 ¾S/cm at 25 °C, and free of any organic impurities.  This is ultra pure quality water (UPW). Within, depended on application, can change the direction for microcontaminants.
