CSIR-CMERI develops technology for quality drinking water

With many cities in India facing a drinking water crisis, the CSIR and CMERI have announced that they have developed three technologies, for serving quality drinking water from groundwater sources

With water scarcity looming large across the globe, the Council of Scientific and Industrial Research (CSIR) and Central Mechanical Engineering Research Institute (CMERI) of Durgapur, on July 2, 2019, announced the development of new technologies for supplying quality drinking water. Director of CSIR-CMERI Harish Hitani, said that the new technologies developed, were based on the principles of oxidation, precipitation and filtration. They do not require electric power and are completely green.

“We have developed three technologies for serving quality drinking water from groundwater sources, which is free from contaminants arising from the presence of iron, arsenic and fluoride”, he told a news conference, in Kolkata. The technologies developed by CSIR-CMERI would be transferred to two private companies based in Haryana and Howrah in West Bengal.

India is facing a drinking water crisis and a NITI Aayog report, has predicted that 21 cities of the country would have no drinking water of its own by next year. Groundwater is a major source of drinking and agricultural usage in the country. However, at a number of locations, contaminants such as arsenic, iron and fluoride in groundwater exceed the permissible limits, causing severe health hazards, Hitani said. “To solve such problems, CSIR-CMERI is continuously researching on water conservation, as well as water filtration management. The technologies developed are ready for commercialisation,” he said.
