Electrodialysis (ED) and Bipolar Electrodialysis (BPED)

For value added demineralization of process streams and byproduct generation.

SUEZ’s electrodialysis stacks and systems transfer ions and minerals out of a process stream for value-added product demineralization. This technology is used in markets and applications such as whey demineralization in dairy plants, glycerine and amine desalting, and juice deacidification. BPED can be used in several applications, including organic acid production, pH adjustment in beverages, or using industrial brine to generate value added acid and caustic byproducts.

Applications

ED and BPED Applications

Electrodialysis:

  • Dairy: whey and permeates demineralization
  • Brine concentration
  • Upstream Oil & Gas: Removal of heat stable amine salts, demineralization of glycol solutions
  • Wine stabilization
  • Glycerine desalting
  • Demineralization of dextrose

Bipolar Electrodialysis:

  • Organic acid production
  • Mining waste recovery
  • Brackish water reverse osmosis recovery enhancement
  • Food & Beverage: pH adjustment, juice deacidification
  • Industrial wastewater reuse for acid and caustic production

Overview

ED and BPED Benefits

  • 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
