Evoqua Water Technologies is introducing new flow range extensions to its Ionpure® Continuous Electrodeionization (CEDI) VNX product line designed to deliver maximised pure water output while offering the potential to use fewer modules or to reduce system footprint.
The Ionpure VNX-Max module achieves the highest flow rate to date in the VNX range, producing up to 22.7 m3/h (100 gpm). Nominal flow is 15.0 m3/h (66 gpm), offering a 20% increase on the next highest output. For applications such as power generation and bulk deionization, Ionpure VNX-Max provides the added capacity to simplify system design by requiring fewer CEDI units and less space uptake.
With the Ionpure VNX-Mini module, Evoqua has focused on minimising the overall dimensions of the unit while retaining a high flow rate of up to 17.9 m3/h (79.2 gpm). Nominal flow rate is 12.0 m3/h (52.8 gpm) This allows construction of smaller CEDI skids per unit of output, a benefit for projects where floor space is at a premium and for minimizing shipping cost by maximizing system flow per shipping container.
“With direct feedback from our yearly survey, while some found our existing high flow modules great for scaling up to bigger systems, others asked for a higher output, size for size," explains Evoqua’s Global Product Manager for Ionpure CEDI modules, Nick Armstrong. "It mostly comes down to the variation in scale of typical end applications. By introducing two different, high flow rate options, we know they have greater scope than ever to reduce size, cost and complexity of pure water and ultrapure water plant.”
Both new modules are available bundled with the recently introduced DC3 power controller. This three-phase switch mode power supply is compact and avoids the need for a separate isolation transformer.
Ionpure VNX-Max modules and VNX-Mini modules feature a fiberglass housing with an integral FlexmountTM end block for easy assembly and connection. They are guaranteed to give leak-free operation up to 100 psig (7 bar).
