What recovery rate can be expected from an EDI system?

The expected recovery rate from an Electrodeionization (EDI) system is typically in the range of 90% to 95%. This is due to the efficiency with which EDI systems remove ionic contaminants from water. EDI utilizes an electric field to drive the ion exchange process, enhancing the removal of dissolved ions while minimizing the need for chemical regenerants.

The high recovery rate reflects the ability of EDI to continuously treat water with minimal waste generation. In practical applications, the efficiency of the system can be influenced by factors such as feedwater quality, system design, and operational parameters, but generally, achieving recovery rates close to 95% is common. This makes EDI systems a favorable option for processes requiring high-purity water, as they can significantly reduce waste compared to other ion exchange methods.
