CECHLO®

CECHLO® systems generate high strength sodium hypochlorite on-site, using either brine made from delivered salt or seawater. CECHLO systems can also be used for salt-splitting for enhanced recovery applications with the 2/3 compartment cell systems.

CECHLO

De Nora CECHLO® systems are designed for use in different electochemical processes:

CECHLO® systems were originally developed as electrolyzers for the chlor alkali industry by Chlorine Engineers Japan (CEC) now part of the De Nora / tkIS joint venture tkUCE.

This globally proven ion exchange membrane electrolysis technology has been used to create a complete product family of electrolyzers devote to the sodium hypochloride or chlorine (and caustic) generation from brine or seawater.

The CECHLO® product family can be summarized as:

Salt-splitting

Salt-splitting

In addition, CECHLO® technology has continued to evolve and has now been deployed for salt splitting operations.

This electrolyzer utilzes two or three compartments cells.  In three compartment cell systems, an intermediate salt brine feed chamber is located between the anodic and cathodic compartments, and is designed specifically for salt splitting applications.

These systems are fast growing due to their suitability in the increasingly popular “ZERO DISCHARGE” or “FULL RECYCLING” processes.
