Water for Injec­tion

The Ph. Eur. and the USP allow both distillation and membrane-based processes for the production of WFI. Are you aware of which solution is best for you?

Producing WFI. Hot or ambient?

The Ph. Eur. and USP leave you free to choose - good reasons for a correct deci­sion.

The rules were clear for decades: WFI had to be distilled. Since 2017, customers have been free to choose. In the search for the right process, BWT provides inde­pen­dent and neutral advice because our product port­folio offers excel­lent solu­tions for both options.

Together, we can look at all rele­vant factors such as the needs profile and the status quo before carrying out a tailored feasi­bility study.

Discover the MULTISTILL and MULTITRON WFI units, the VAPOTRON Pure Steam generator, and the compact, cost-effective COMBITRON, which produces both.

Cont­a­m­i­na­tion Control Strategy - A Guide for Phar­ma­ceu­tical Water Systems

Learn how to implement a contamination control strategy for your water purification system, compliant with EU GMP Annex 1.

Water is an essential ingredient for the pharmaceutical industry, but it also poses a significant risk of microbial contamination. To ensure the quality and safety, a contamination control strategy (CCS) for the water purification system should be implemented, as stated in the EU GMP Annex I. A CCS is a holistic approach that covers the design, operation, maintenance, monitoring and documentation of your water system. It is based on a contamination risk management (CRM) that identifies and mitigates all potential sources of contamination.

OSMOTRON

It is widely believed to be the undis­puted bench­mark in producing Puri­fied Water. Every­thing is installed on a compact frame: Prefilter, soft­ening, reverse osmosis, and SEPTRON elec­trodeion­i­sa­tion. Oper­a­tors have the entire process under control at all times with AQU@View automa­tion.

  • Stan­dard­ized, ready for connec­tion, and prequal­i­fied
  • Readily acces­sible for sampling and main­te­nance
  • Ready for the future: Modular expan­sion
  • Up to 12 m³/h PW on one frame, up to 30 m³/h as multi-​skid
  • Our top seller: World­wide > 1,000 systems in oper­a­tion

LOOPO C

Great things in small pack­ages. In our opinion, there is only one correct answer for the safe storage and distri­b­u­tion of PW to the point of use: The LOOPO. Thanks to the ozone gener­ated directly by STER­ITRON from Puri­fied Water, the micro­bi­o­log­i­cally crit­ical tank is safe. Water is free of ozone in the loop as BEWADES UV removes it until below a detectable level—unless it is required to auto­mat­i­cally ozonize the whole loop system on occa­sion.

The LOOPO is avail­able in various stan­dard­ized sizes with circu­la­tion rates in any size.
