New Delhi: Innovative technologies by an IIT Kharagpur-based center of technological excellence focusing on water purification have helped deliver clean and safe drinking water and also manage floods in several states across the country.
An efficient, low-cost, nano-filtration-based technology by The Centre for Technological Excellence in Water Purification (CTEWP) housed in IIT Kharagpur has ensured access to safe and clean drinking water free of heavy metals for 25,000 people in three different locations in Telangana and Andhra Pradesh.
The prototype of the highly compact vertical modular nanofiltration membrane system designed for removal of heavy metals from the groundwater was developed by the Membrane Separations Laboratory, CSIR-Indian Institute of Chemical Technology (IICT), with support from the Department of Science and Technology (DST) Water Technology Initiative (WTI). With a capacity of 100 – 300 Litre per hour(L/h), the system based on a membrane technically
