The process of electrochlorination is simple. It is the electrolysis of saltwater to produce a chlorinated solution. The first step is removing any solids from the saltwater. Next, as saltwater streams through an electrolyzer cell's channel of decreasing thickness. One side of the channel is a cathode, the other is an anode. A low voltage DC current is applied, electrolysis happens producing sodium hypochlorite and hydrogen gas (H2). The solution travels to a tank that separates the hydrogen gas based on its low density. Only water and ordinary salt, (sodium chloride (NaCl)) are used.
