WFI systems

Since April 2017, the new monograph on WFI in the European Pharmacopoeia (PhEur) has been legally binding. After the implementation of the monograph for HPW (2002) this movement was a logical step by which the combination of reverse osmosis and ultrafiltration for the treatment of HPW analogous to the quality of WFI was confirmed.

Werner WFI systems for the preparation of Water for Injections according to PhEur, USP or JP may also be delivered as pre-qualified compact plants, ready for connection. The compact package unit construction technique on a stainless steel skid provides all the required processing technologies, which will be adapted specifically to the prevailing quality of the potable water. In addition to special techniques of drinking water conditioning in individual cases, e.g. upstream ultrafiltration, every pre-qualified compact plant with a performance range from 100 to 25,000 LPH is composed of the following components:

  • double softening, serial connection, quality-controlled, alternative conditioning according to the drinking water ordinance (TVO) and ESR or HOD
  • recirculation system UV plus
  • reverse osmosis, single- or double-stage construction
  • optional membrane degasification for the reduction of CO2
  • electrodeionization CEDI
  • ozonation or hot water sanitizing at > 80 °C
  • pipes of stainless steel 316L, Ra < 0.80 µm, orbital welding
  • latest control technology Siemens S7 PLC controller with touch panel or panel PC
