Salt electrolysis & replacement cells

Salt electrolysis:

Sodium hypochlorite is automatically produced on site in slightly salted water (>3g NaCl/litre) for water disinfection.
This makes adding chlorine 100% unnecessary.
Salt concentration possible from 3 to 100 grams NaCl/liter.
Sodium hypochlorite disinfects the water and removes unpleasant odors from combined chlorine (chloramines).
