A high-quality water purification system incorporating carbon, reverse osmosis (RO) and continuous electrodeionization (CEDI) was introduced on 23 March 2009 by Siemens AG’s Industry Solutions Division, based in Warrendale, USA.
The IonRight system is designed to provide industries such as metal-finishing and microelectronics with consistent high-purity water from potable feedwater. For applications that require 4-10 gpm (0.9-2.3 m³/h) of high-purity water, the system is a “plug and play” replacement for separate-bed and/or mixed-bed service deionization (SDI).
In addition, multiple IonRight systems can be installed in parallel to accommodate even higher flow rates. The system’s dual-filtration process consistently delivers higher quality water with lower operating costs than traditional portable deionization.
With a compact, skid-mounted design. the robust RO/CEDI equipment allows stable performance and the flexibility to adapt to changing feed water conditions. Other claimed benefits include easy transport, installation and operation, with no on-site maintenance required, as the RO membranes and CEDI system are cleaned off-site at Siemens’ local service branches.
An integrated control panel and power supply features auto on/off operation with an “instant on” feature. Included with the system are conveniently scheduled service visits from Siemens’ highly qualified local service technicians.
When the system is connected to the customer’s potable feedwater source, the water enters a carbon pretreatment 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.
