EDI for Power Generation

SnowPure provides EDI modules for power generation market, since 2002. Power plants around the globe utilize our Electropure electrodeionization (EDI) including plants in the United States, China, Europe, and the Middle East. With our high capacity EXL EDI product we are able to serve a greater share of the boiler feedwater high purity water market.

Boiler Feedwater Requirements

Combined-cycle power plants and all high-pressure steam turbines require high purity water, virtually free of silica. SnowPure’s electrodeionization (EDI) and gas removal membrane (GTM) products for O2 and CO2 removal. These membranes replace traditional chemical-based resin systems and open degasifiers, enabling an environmentally superior water system.

Silica Requirements  

Turbines <10 ppb

Electropure EDI

<1-5 ppb


Examples of SnowPure’s Electropure EDI installations include:

  • 821 MW (megaWatt) power plant in Texas with a 200 gpm RO+EDI system
  • 235 MW power plant in Poland with a 100 gpm RO+EDI system
  • 377 MW power plant in Israel with a 120 gpm RO+EDI system
  • Over 50 power plants in China

Typical high purity boiler feedwater treatment deionization systems consists of the following processes:
