Field evaluation of a hand-powered reverse osmosis system for sustainable water purification in off-grid rural India
Summary. Researchers developed and tested a hand-powered reverse osmosis water purification system in rural India that operates without electricity. Field trials over six months in West Bengal and Rajasthan showed the system rejected 88–94% of dissolved solids while using half the energy of commercial alternatives. Community surveys confirmed users accepted the technology and valued the improved water quality, demonstrating viability for off-grid rural areas lacking infrastructure.
