UAT™ Electrodeionization

UAT™ EDI系统采取RO渗透液,连续生产超纯水,适用于半导体、电力和特种化工行业。 与传统的混合床离子交换系统相比,无需使用再生药剂,以较低的运行成本生产出高纯度的水。


High Purity Water Production

Low Operating Cost

No Hazardous Wastes Produced

Small Footprint / Modular Design

Electrodeionization is the combination of ion exchange resins, ion exchange membranes, and electricity to separate ions from water.  The ion exchange resins behave exactly like a mixed bed polisher, however the electric field aids in the hydrolysis of water to produce hydrogen and hydroxide ions which continuously act as regenerants.  The combination of technologies allows for > 16 MΩ-cm water to be continuously produced with no downtime for operator intensive regeneration procedures.  The chemical free regeneration also minimizes storage and waste handling equipment, creating a small footprint and economical system.  The concentrate stream from the EDI is typically lower TDS than the raw plant water and can be re-used for other purposes (depending on the application) to increase efficiency.

Why UAT™?

  • Continuous high purity water (> 16ΩM-cm) production without the need for operator intensive regeneration procedures
  • UAT™ EDI modules don’t require regenerant storage or waste neutralization pits – minimizing footprint and CAPEX costs.
  • Low energy consumption means higher efficiency and low OPEX costs.
  • Piping, instrumentation, and electrical components are included, and skid mounted for easy implementation   
  • Combination with UAT™ RO systems provides consistent and reliable feed quality for smooth operation
