nafion candles
FOR eTCHING BATHS
NAFION candles are used to treat and regenerate etching baths by electrodialysis.
Electrolysis is performed by the electric fields created between the electrodialysis cells and the planar electrodes.
Reoxidation modules
FOR BATH TREATMENT AND REGENERATION
The reoxidation module consists of a set of membrane electrodialysis cells immersed in an electrolysis tank fitted with planar electrodes.

The process for treating etching baths
BY ELECTRODIALYSIS
Depending on the case, the etching bath circulates in the tank or inside each electrodialysis cell. Conversely, the exchange solution (catholyte) circulates in the other compartment (cell or tank).
