UK university research offers water purification solutions for Indian farmers

London, Oct 21 (PTI) Water experts at the UK's University of Birmingham say they have designed a low-energy and high-efficiency means of purifying water for India’s rural farming communities, which could allow farmers to safely use high-saline groundwater and wastewater to grow crops.

Working in Gujarat, scientists in the Birmingham-led India-H2O project have used emerging membrane technologies that allow saline groundwater and domestic/industrial wastewaters to be safely and efficiently recycled. Based on field work in the village of Lodhwa, which confirmed the poor quality and availability of water in the region, scientists believe they have now designed a system that can recover 80 per cent of the unusable groundwater fed into it – producing usable water with low energy consumption.
