Electrodialysis (ED) and Bipolar Electrodialysis (BPED)
Improve whey demineralization, glycerine desalting, and juice deacidification
Valuable constituents are often lost in waste streams, but GE’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 GE’s modular system designs
