Technology provides high-purity water for industries
Siemens has introduced the IonRight system, a technology for providing industries such as metal finishing and microelectronics with consistent, high-purity water from potable feed water.
Designed for applications that require 4 to 10 gal per minute of high-purity water, the system is a “plug-and-play” replacement for separate bed or mixed bed service deionization (SDI). Multiple IonRight systems can be installed in parallel to accommodate higher flow rates. The system’s dual-filtration process consistently delivers higher quality water with lower operating costs than traditional portable deionization. The system is currently available in North America.
The IonRight system incorporates carbon, reverse osmosis (RO) and continuous electro-deionization (CEDI) technologies in a compact, skid-mounted design. The RO/CEDI equipment allows stable performance and flexibility to adapt to changing feedwater conditions.
After being connected to the customer’s potable feedwater source, the water enters a carbon pre-treatment vessel, which removes chlorine, chloramine and other organics that could damage the RO and CEDI membranes. The water then flows into the RO membrane housing, where the bulk of the water contaminants (dissolved solids) are removed. From there, the water enters the CEDI vessel, where it is polished to a purity level of 1.0 megohm or greater. An optional twin alternating softener is also available as pretreatment, if required.
