EDI / SERIES OVERVIEW

KDM EDI modules

KDM electrodeionization modules for continuous polishing of suitably pretreated RO permeate.

APPLICATION FIT

RO permeate polishing

TECHNOLOGY IN CONTEXT

A precise fit for your water process.

Ions migrate through selective membranes under a DC field. Ion-exchange media support continuous polishing of suitably pretreated RO permeate.

Electrical basis
Current is DC. The voltage table does not print a unit; no voltage unit is inferred.

Specify with confidence.

Confirm the exact model, current data-sheet revision, feed-water limits and test conditions before finalizing your design. The published specifications follow the designated source for this series; no legacy-only model variants are combined into this table.
