ELECHLOR^® onsite sodium hypochlorite generators produce chlorine in the form of sodium hypochlorite by means of electrolysis of salt solution. Salt is at random charged in the salt saturator tank to form a saturated brine solution. This solution is then diluted to the required concentration in the brinometer assembly. The diluted solution is then passed through the electrolytic cell where low voltage D.C. is applied by a specially designed power supply unit for electrolysis, to produce sodium hypochlorite. The reaction is as below:
2Nacl + 3H²O = 2e + NaOCl + NaCl + 2H²O + H2
The Hypochlorite solution thus produced is then directly injected back into the mainstream for disinfection of the water.
