The Indian Institute of Technology Guwahati (IIT-G) has recently signed a memorandum of understanding (MoU) with RD Grow Green India private ltd, which made it possible to treat contaminated groundwater without using any chemicals. Drinking water contamination is a major problem in most states, including Assam. This chemical-free treatment technique might be useful to citizens both in rural and urban areas.
RD Grow Green India is an incubating company at the Technology Incubation Centre in IIT Guwahati and is working on this project for the treatment of contaminated drinking water and industrial effluents.The company is capable of handling arsenic, iron and fluoride contamination in Assam in collaboration in an appropriate manner with the state government.
At least 24 districts in Assam currently face the problem of either arsenic or flouride contamination of groundwater. According to government statistics, groundwaters in at least 6,881 locations of Assam are found to be contaminated by arsenic, while there is fluoride contamination in 930 locations across the state.
Professor Purkait said the technology is based on the principle ‘apparatus and method for removal of fluoride, iron, arsenic and microorganisms from contaminated drinking water.’
