CER - Caustic Etch Recovery System

Etching or chemical milling with caustic soda can often be the greatest operating expense in aluminum anodizing. Our CER Caustic Etch Recovery System continuously crystallizes and removes dissolved aluminum from caustic soda etchants and returns the caustic to the etching/milling tanks for reuse resulting in reduced chemical costs, waste treatment costs, and labor requirements. The separated aluminum trihydrate crystal contains a marketable and salable value.
