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)
- high quality after-sales services
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.
|Conductivity||μS/cm@ 20 oC||-||≤ 4,3|
|Conductivity||μS/cm@ 25 oC||≤ 1,3||-|
|Nitrate (NO3)||ppm||-||≤ 0,2|
|Hard metal||ppm Pb||-||≤ 0,1|
|Aerobacterium||CFU/ml||≤ 100||≤ 100|
|Highly purified water|
|TOC||ppm C||there is no similar standard||0,5|
|Conductivity||μS/cm@ 20 oC||there is no similar standard||≤ 1,1|
|Nitrate (NO3)||ppm||there is no similar standard||≤ 0,2|
|Aerobacterium||CFU/100 ml||there is no similar standard||≤ 10|
|Bacterial endotoxins||l.U./ml||there is no similar standard||≤ 0,25|
This industry requires ion-free water with the highest theoretical purity; conductivity is as low as 0,055 µS/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.
