The generation of sodium hypochlorite requires only:
seawater + electricity or fresh water + salt + electricity
The following table shows the consumption of a typical plate electrolyser when generating hypo containing 1kg chlorine:
SEA WATER SYSTEM (2,000 PPM)
FRESH WATER + SALT SYSTEM (8,000 PPM)
•4.2 kWh (AC)
•500 litres seawater
•no salt required
•5.5 kWh (AC)
•125 litres fresh water
•3.5 kg salt
