R. Elango, a chemical engineer by qualification, who was a former scientist at the Council of Scientific and Industrial Research and later served as the president of Kuthambakkam panchayat in Tiruvallur district has designed a unit that can manufacture sodium hypochlorite using solar power. Sodium Hypochlorite is the disinfectant used in various concentrations for different purposes.
Sodium Hypochlorite is usually manufactured in industries through the process of electrolysis in which electricity is passed through titanium electrodes immersed in salt solution. Mr. Elango says that his design can meet the increasing demand for the disinfectant.
Mr. Elango’s model consists of a barrel fitted with 2 electrodes is filled with salt water solutions of high concentration. Electric current generated through solar power is passed through the electrodes. In 8 hours, sodium hypochlorite solution can be obtained through the tap attached to the barrel.
Currently, he has designed the unit for two capacities – 25 litres and 210 litres. The input required is just 750 g of salt and 25 litres of water for one cycle.
