•Case Study: Healthcare Products Manufacturer Integrates Technologies To Reduce Costs, Promote Gentle Global Footprint
By Siemens Water Technologies
A large healthcare products manufacturer in the United States needed to improve its environmental impact while substantially reducing excessive costs associated with municipal discharge and the operation of cooling towers.
The existing purified water system included pre-filtration, activated carbon, two-pass reverse osmosis (RO) units and polishing deionization. It ran in a good manufacturing practices (GMP) environment, and was thus subject to all GMP requirements.
Although the system was operating well and running at technical efficiencies, the size of the system resulted in a nearly continuous waste stream in its seven-day operation period and would experience periods of complete recirculation when the purified water product was not needed, causing unnecessary additional costs. Also, the feed water to the existing system was high in total dissolved solids (TDS), causing the concentrate, or waste stream, of the RO to have a very high TDS level and high conductivity.
