In order to address problems in the Indian water sector, the Indian Institutes of Technology Guwahati (IIT Guwahati) and Bombay (IIT Bombay) have worked along with European partners.
According to a statement from IIT Guwahati, both institutions are actively working to address the alarming problems in the Indian water sector as part of the Indo-European project “Low-cost Innovative Technology for Water Quality Monitoring and Water Resources Management for Urban and Rural Water Systems in India” (LOTUS).
According to the release, the LOTUS Indo-European initiative seeks to address many problems in the Indian water industry. A key component of the LOTUS project is a novel water quality sensor that builds on earlier work by the Ecole Polytechnique, Paris, France, and has been further developed by researchers at the Université Gustave Eiffel in association with the Indian Institute of Technology, Guwahati, and the SME EGM, Sophia Antipolis, France, throughout the project.
The LOTUS sensor’s central component is a chip with Carbon Nanotube (CNT)-based sensing elements that can measure a variety of quality indicators, such as total dissolved solids (TDS), hydrogen potential (pH), chlorine, and arsenic.
“LOTUS water quality sensor requirements are established after collecting requirements from Indian water utility owners, operators, end users and R&D experts and therefore LOTUS sensor is expected to satisfy requirements of Indian water industries,” Professor S Senthilmurugan, Department Chemical Engineering and Chairperson, Technology Incubation Centre, IIT Guwahati, said
From July through December 2023, the IIT Guwahati LOTUS project team intends to work with LOTUS partners to showcase LOTUS solutions in Guwahati and Bangalore. The LOTUS sensor will be installed in the first level to let users know how well their water is being provided to them through pipes, tanks, and groundwater as well as to reduce leaks in the piped supply. According to the statement, LOTUS solutions will be used on a second level to demonstrate the ideal dosage of disinfectants.
