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.

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
