KOLKATA: The city based NB Institute of Rural Technology has come up with the module of a solar power run water purifier machine that will purify 200 litre water in three hours using solar power. The technology is scheduled to be formally launched by union minister Harsh Vardhan this weekend and the first such machine would be installed at an orphan school in Kalikapur area early next month, very close to Baghajatin area that has been recently hit by enteric diseases due to water contamination.
Solar power expert Santi Pada Gon Chaudhuri who heads the institute has been working over the past one year to develop the technology. “The water purifier machine removes the iron and other impurities from the water and also kills bacteria through a UV lamp. The entire power comes from solar energy and there is no battery storage.
The solar energy is stored in the form of pure water which will be adequate for two days of back up. The machine could be installed anywhere inside a house and solar energy would be brought into the machine through a panel that would be fixed outside,” Gon Chaudhuri said.
Gon Chaudhuri said that two kinds of model would be manufactured for domestic and institutional purpose. “The domestic model that would have a price of about Rs 25,000 would have a 100 litre water tank and the institutional model that will be double in price of about Rs 50,000 will have a 200 litre water tank capacity. A 200 litre water would be purified within three hours using 50 watt solar power per hour,” he said.
