Electrochlorination is an electrolysis process where either: natural seawater, or, an artificial brine solution (fresh water + salt) is converted into sodium hypochlorite solution

Salt is composed of sodium and chloride. When in solution and DC (direct current) is passed through titanium electrodes, the chlorides will disassociate to form chlorine. The process is basically as follows:

•	Electrolysis occur in an undivided cell when a DC current is passed through a saline water solution (e.g. seawater or brine solution)
•	At the anode: Oxidation of chloride ions to produce chlorine (Cl2)
•	At the cathode: Reduction of water to produce sodium hydroxide (NaOH) and hydrogen (H2)
•	Liberated chlorine reacts with the sodium hydroxide to produce sodium hypochlorite (NaOCl) instantaneously
•	The overall reaction, sustained by electrical energy, is as follows:

2NaCl (salt) + H2O (water) NaOCl (hypo) + NaCl (salt) + H2 (hydrogen)

The typical seawater electrochlorinator comes with the following basic flow process:
