Electromat* Electrodialysis (ED)

For Whey Demineralization

GE focuses on improving our customers’ proc­esses and enhancing their products with our Elec­tromat Electrodialysis (ED) and Bipolar
Electrodialysis (BPED) Systems. Our history in ED
began in 1950 when Ionics developed the first ED
system. We expanded into process applications in
1961 when Ionics with Wyeth & Foremost devel­oped and installed the first whey ED production
system. Acquired by GE in 2005, Ionics and now
GE have continued to research and develop the
technology over six decades to improve its per­formance.

Description & Use

Rich in milk sugar (lactose) and whey proteins, re­duced minerals whey is used in infant formula, ice
cream, energy drinks, dry mixes and other food
products. Since reduced minerals whey is becom­ing a more common ingredient in food, there is a
growing need for efficient and cost effective dem­ineralization processes. GE’s ED systems can meet
this need.

Dairy Solutions Processed by ED

Customer Benefits

Economical

• Increases profits by enhancing product value.

• No chemical regeneration required, reducing

chemical consumption and disposal.

• Minimal dilution of solids, for lower
evaporation cost.

• True continuous process. Typical hold-up time
is <15 minutes.

• Continuous production of 25 to 90%
demineralized whey without blending.

• Cost-efficient manufacturing and ED stack
design for lower operational expense.

• Organic fouling resistant for reduced down
time and lower membrane replacement costs.

• Number of cell pairs in the ED stack can be
adjusted to optimize efficiency, as well as
operational and capital cost.
