EDI continuously polishes RO permeate to 16–18 MΩ·cm without acid/caustic regeneration, eliminating hazardous chemicals, downtime, and neutralization systems. Plants gain steadier resistivity, lower operator risk, and smaller footprints. Over multi-year horizons, reduced consumables and fewer production stops improve total cost of ownership.
Mixed-bed stacks mimic traditional mixed-bed polishers, delivering the tightest ions leakage and fastest commissioning for UPW. Separated-bed designs help where ion loads are unbalanced or fouling selectivity is needed, trading peak purity for resilience and serviceability. The decision hinges on feed chemistry, boron/silica targets, and maintenance philosophy.
Plate-and-frame provides robust hydraulics, uniform current distribution, and scalable rack architectures that hold resistivity under transient loads. Compared with spiral wound, it tolerates a wider operating window and integrates cleanly with RO→EDI skids, which is why semiconductors, power, and pharma standardize around it for mission-critical UPW.
Advances such as resin-wafer EDI (RW-EDI) and membrane-free EDI (MF-EDI) reduce ohmic losses and enhance mass transfer, enabling ~0.1–0.3 kWh/m³ operation in optimized duty. Coupled with smarter RO pretreatment and tighter TOC control, plants see longer stack life, fewer cleanings, and steadier product resistivity.
Beyond polishing, EDI is moving into boiler make-up for high-pressure units, selective metals removal in industrial wastewater, and compact lab/clinical systems (integrated RO+EDI skids). Chemical-free operation helps sites meet ESG targets while simplifying permits, and modular designs speed deployment in space-constrained retrofits.
