WHAT IS ON–SITE ELECTROCHLORINATION? 

It is a simple and proven technology to convert ordinary salt (or sea water), by means of electrolysis into 1st grade sodium hypochlorite (ELECTRO HYPO). It is always applied on-site, at the Point of Application. No chemicals other than ordinary salt are used throughout the process.
A diluted brine solution (or sea water) is fed through an electrolyser cell. When a low voltage DC current is applied, electrolysis occurs and sodium hypochlorite (NaOCl) is generated instantaneously ELECTRO HYPO is generated between 0.2% and 0.8% depending on the application. Below 1%, Hypo is classified as a non-hazardous chemical although still a very effective disinfectant. The only by-product, hydrogen, is safely vented into the atmosphere.

ELECTROLYSIS PROCESS
The process is based on the chemistry of electrolysis of sodium chloride.
On passing direct current through an aqueous solution of sodium chloride (NaCL), which is combined to Na+ and cl-?

NaCL solution

2NaCL(aq)  2Na+(aq) + 2CL-(aq)
Free chlorine is generated at the anode

2CL-   CL2  + 2e-.
Hydrogen is evolved at the cathode
2H2 + 2e-.  2OH- + H2  ­
OH- ions migrate from the cathode and react with Na+ and CL2 near the anode, thus producing sodium hypo chlorite Naocl.
As follow expressed overall chemical reaction.
2NaOH + CL2  NaOCL + Nacl + H2O
