INTRODUCTION
On-Site Generation of Sodium Hypochlorite ( on-site at the Water Treatment Plant ) has been in commercial use for over 30 years. Power Stations are significant users of on-site generation systems, however the technology has not been as widely utilised in Water Treatment Plants due to the operating costs compared to that of Bulk Chlorine products. However, recent advances in Electrolyser Cell Technology (namely, Applied Thermodynamic Management of the Cell) have reduced capital, operating and maintenance costs and made this technology much more viable. In addition, Occupational Health and Safety issues have caused Water Utilities and Consultants to specify the technology in place of Chlorine Gas and Commercial Grade Sodium Hypochlorite. There are now a large number of WTP’s and commercial swimming pools worldwide utilizing on-site Sodium Hypochlorite generation systems.
THE PROCESS
NaCl + H20 + 2e -------------------- NaOCl + H2
Salt + Water + Energy -------------------- Hypo + Hydrogen
These small-scale generators, which are used by the World Health Organization in the production of hypochlorite, that is, bleach, among disinfectants effective against viruses and bacteria, including Covid-19; It is a perfect solution for public institutions, hospital, hotel, school, factory, municipality, senior care facilities and other places.
