Home Water Desalination

Due to the lack of reliable municipal water supply services and the increase in consumer awareness of water-borne diseases, the domestic purification industry was expected to grow at 25% compounded annually between 2012 and 2015. Domestic point-of-use home purification industry was anticipated to be worth 1.5 billion USD industry in India at the end of 2015, with reverse osmosis (RO) systems accounting for 43% of the total share. However, with the per-capita consumption forecasted to increase nearly two-fold to 167 L/day from 2000 to 2025, the condition of water supply in India will be in a critical state. In this environment, the use of RO systems - which waste between 50 to 75% of the input water - will be undesirable. Instead, the GEAR Lab is developing an alternative solution that relies on electrodialysis (ED) to achieve a higher recovery of 90% while maintaining cost-competiveness with existing RO products in India.
