Sustainable Water Treatment With CDI
Water supports life of all organisms on Earth, and it is essential to drink safe water for healthy living. Drinking contaminated water causes a host of diseases such as typhoid, dysentery and cholera, which can be life-threatening. InnoDI (Innovative De-ionisation) Water Technologies, an IIT-Madras incubated startup, was founded as a joint venture between Milano-based Idropan Dell’Orto Depuratori and Bengaluru-based AquaSphere Greentech Solutions in 2016. Their aim is to globally deploy Capacitive Deionisation (CDI) technology for economical and sustainable water treatment by decreasing water and energy wastage (with DC power) when compared to traditional RO systems
