The advantages of Electrodeionization (EDI) compared to Mixed Bed
systems are numerous. EDI offers a more advanced technology,
eliminating the need for regeneration chemicals or neutralization
systems. This results in significantly lower operating costs and a
more environmentally friendly solution. Additionally, EDI systems
offer continuous and simplified operation, leading to improved
process efficiency. Furthermore, with a smaller footprint and
reduced building height requirement, EDI systems are easier to
integrate into existing industrial facilities. Overall, EDI
technology offers a cost-effective, environmentally friendly, and
efficient alternative to Mixed Bed systems.
