Membrane-based PW, HPW and WFI generation
Syntegon offers a modular, turn-key solution for the “cold” membrane-based generation of pharmaceutical-grade pure water (PW), high purity water (HPW), and water for injection (WFI). Employing a full range of technologies including multi-layer filtration and ultrafiltration as well as physical-chemical processes including reverse osmosis and electrodeionization, our systems are configured to precisely address your individual requirements. Storage can be either hot or cold. Our approach substantially reduces the associated footprint, energy consumption, investment costs, qualification expenses, and ongoing maintenance costs when compared to traditional distillation-based systems.
Features of our membrane-based pure media systems
Syntegon’s membrane-based pure media systems are robust, proven modular solutions that can be easily and quickly configured to meet your specific requirements. All modules are pre-tested and readily available. With a nominal production range of 200 to 20,000 liters per hour, the skidded systems are suitable for clinical and commercial manufacturing facilities alike.
Syntegon uses the highly energy-efficient “cold” membrane process of reverse osmosis, along with electrodeionization and ultrafiltration, in a modular, full-featured design. Storage can still be either hot or cold. This approach substantially reduces the initial capital investment, required footprint, energy consumption, as well as the ongoing qualification and maintenance costs when compared to traditional distillation-based systems.
Footprint and serviceability
Featuring a small footprint and height in all configurations for easy drop-in installation, the modular design is highly hygienic and accessible, making maintenance quick and easy. Measuring devices and sensors throughout ensure that the filter and water quality are monitored and maintained during the entire production process.
Water for injection (WFI) is an essential utility in pharmaceutical manufacturing that has traditionally been generated through the energy-intensive process of distillation. The recent revision of monograph 0169 of the European Pharmacopoeia, however – which has aligned the EP with the US and Japanese Pharmacopoeias in allowing suitable techniques other than distillation for the generation of WFI – has now made highly energy-efficient membrane-based systems a universally accepted alternative.

Frequently asked questions
WFI has traditionally been generated through the energy-intensive process of distillation, but the recent revision to monograph 0169 of the European Pharmacopoeia (EP) has now also made techniques other than distillation universally accepted. The revision has finally aligned the EP with the US and Japanese Pharmacopoeias in allowing more energy efficient alternatives. Syntegon acted on this regulatory change right as it took place and was among the first industry suppliers to introduce the new type of generation unit for WFI in Europe. Our MWFI system uses the “cold” membrane process of reverse osmosis, along with electrodeionization and ultrafiltration, in a modular, full-featured design. Storage can be either hot or cold.
In essence, the unit must produce water under tightly monitored conditions that eliminate impurities and prevent the growth of microorganisms. Regular sanitization of the unit using hot water or chemicals prevents the formation of biofilms. Syntegon’s systems offer both options. Monitoring all the processes in the production chain (in particular the integrity of the membranes) is essential to guaranteeing the microbial quality of the water, which is why Syntegon outfits its systems with a variety of sensors and measuring devices. We monitor total organic carbon (TOC), conductivity, and other important parameters of water quality throughout. An online microbe counter is also available as an option.
The operating cost differential depends primarily on the consumption level and the efficiency of the correspondingly sized thermal generation system (i.e. the number of distillation columns in the system). On the low end, for pilot and small-scale facilities with an annual consumption of around 5 million liters per year, typical savings are in the order of ~30%. On the high end, for large facilities with 40 million liters or more of annual consumption, savings can easily reach ~40%. These are typical savings that factor in maintenance and materials in addition to the utilities consumption. We invite you to get in touch for a tailored assessment of the savings potential in your particular facility.
Ozone as a treatment agent remains somewhat problematic to handle and difficult to measure accurately in solution. And since turning to hot storage (to avoid ozone treatment) no longer means bigger, more expensive, and energy-hungry generation systems, hot storage is a fully financially viable solution for many customers. With the hot WFI storage option now standard for the MWFI, customers need not compromise. But Syntegon offers comprehensive hot and cold storage and distribution options alike. The specific use case determines which storage type is the better option for each customer.
