In pharmaceutical manufacturing, water purity is critical. Every batch, every process, and every patient depends on water that meets the industry’s most demanding global standards. As the industry evolves, regulations tighten and sustainability goals grow, manufacturers must achieve exceptional purity – while improving efficiency and controlling costs.
Achieving and maintaining high purity water – free from ionic contaminants, organic compounds and microbial impurities – requires a finely tuned, highly reliable treatment process. Parameters such as conductivity and total organic carbon (TOC) must be continuously monitored and carefully managed. Meeting required standards typically involves multi-step purification technologies, including UV treatment and deionization, all integrated to deliver consistent performance.
This is where Xylem comes in.
With decades of experience and proven technologies, our experts work closely with manufacturers to design, optimize, or upgrade systems that enhance water quality, increase reliability, and reduce total operating costs. Whether it’s for a new build facility, expanding capacity, or retrofitting aging infrastructure, Xylem’s advanced treatment technologies and global service network ensure long-term performance and peace of mind.
Continuous Electrodeionization (CEDI)
CEDI is the leading technology for ultrapure water production. It replaces chemical-based ion exchange with an electrochemical process that works by combining resin, electricity, and ion-exchange membranes to remove ionized or ionizable impurities – including carbon dioxide, boron, and silica. Unlike traditional processes, such as mixed bed deionization, CEDI is a continuous low energy consuming process and avoids the need for chemical regenerants, delivering a wide range of efficiency, safety and cost benefits to manufacturers.
Ultraviolet (UV)
UV technology plays a vital role in the generation of ultrapure water. It provides a powerful, chemical-free method of controlling microbial contamination and reducing total organic carbon (TOC). Without treatment TOC, which presents in all untreated water, acts as a nutrient for microorganisms. Even small increases in TOC can result in large increases in bacteria. UV light disrupts the DNA of microorganisms, preventing their growth, while specific UV wavelengths break down trace organics. Using UV technology, manufacturers gain an additional layer of protection, helping maintain consistent water quality to support regulatory compliance.
