IIT Jodhpur builds water purification unit for schools in rural areas

11 Aug 2021 CW Team

The Indian Institute of Technology (IIT) in Jaipur has made a spectacular invention by making a low-cost water filtration and treatment unit for the schools in the rural districts of Rajasthan.

To assure that the water is purified and retreated for efficient use, the water purification unit uses membrane-assisted sorption-based Ultrafiltration (UF) technology. The benefit of the innovative unit is that it is portable, and it was first set up in five rural schools in the Rajasthan districts of Sirohi, Jhunjhunu and Jodhpur.

As per the institute officials, amid the pandemic, washing hands several times a day, and cleaning floors, surfaces in public areas, has become a standard method and the most vital one to keep the virus at bay.

As wastewater generation is likewise growing in both rural and urban regions, the requirement for clean water has also increased. To overcome this problem, water budgeting, water auditing and smart water supply are required.

Pradip K Tewari, the Head of the Department of Chemical Engineering, told the media that IIT Jodhpur is using its knowledge to resolve this by utilising a holistic examination of water quality and quantity requirements for the benefit of society. Additionally, he said that water purification, water conservation, wastewater treatment, water resource management, recycling, and reuse are all part of this mission.
