How does CECHLO™ - MS technology work?
The CECHLO™ product family of electrolyzers generates sodium hypochlorite or chlorine gas (and caustic) from brine. Sodium hypochlorite is produced through an electrochlorination process that uses an electric current to convert salt water into chlorine (Cl2) and sodium hydroxide (NaOH), which is then transferred to a hypo-reactor to produce 12.5% sodium hypochlorite.
Steps in the electrochlorination process:
