DUPONT™ Electrodeionization Module Model EDI-310

 DUPONT™ Electrodeionization Module Model EDI-310

Description DUPONT™ EDI-310 Modules are made using a patented spiral-wound design containing membrane and ion exchange resins sealed in a high-strength fiberglassed reinforced plastic (FRP) pressure vessel. The modules can be used in place of conventional mixed bed ion exchange for polishing of reverse osmosis (RO) permeate, eliminating the need to store and handle hazardous chemicals. DUPONT™ EDI-310 modules optimize

performance, maintain continuous product quality, and can produce up to

18 megaohm-cm product water for high-purity and ultrapure industrial water applications.

l Once through concentrate flow path eliminates brine injection and recirculation,

greatly simplifying system designs.

l Distinct spiral design prevents internal and external leaks common with

compression-style plate & frame stacks.

l Easy to clean, non-resin filled concentrate chambers.

l Lightweight modules require no special lifting equipment, allowing for easyaccess,

modular designs.

l Built-in sample port for dilute product water sampling.

l Cost-effective, spiral-wound DUPONT™ EDI-310 modules allow system

integrators to build systems that have both lower capital and operating costs

when compared to conventional mixed bed ion exchange.

Typical Properties Product Water Resistivity ≥ 5 MΩ·cm ≥ 15 MΩ∙cm

Total Exchangeable Anions (TEA) ≤ 25 ppm (CaCO3) ≤ 8 ppm (CaCO3)

Based on standard test solution, actual module performance is based on specific feedwater conditions.
