Electrodialysis (ED) and Bipolar Electrodialysis (BPED)

Improve whey demineralization, glycerine desalting, and juice deacidification

Valuable constituents are often lost in waste streams, but SUEZ’s Electromat* technology can help.

Electrodialysis (ED) transfers ions from one solution to another through selective ion exchange membranes. The process employs DC voltage to achieve the transfer.

Bipolar electrodialysis (BPED) uses a bipolar membrane to split water into H+ and OH-, generating acid and caustic streams. This process adjusts a solution’s pH without adding bases or acids.

ED and BPED Product Features

  • Enhances product value, reduces processing costs, and derives value from waste streams
  • Removes only ionized species, leaving valuable constituents behind
  • Reduces chemical consumption and salt effluent
  • Eliminates wasted energy, time and product because processes can be tuned to meet any product set point
  • Operates simply and reliably using a skid-mounted and automated design that operates in continuous or batch mode
  • Expands easily, as needed, due to SUEZ’s modular system designs
