The development of our capacitive deionization technology started in a group led by Prof. Joydeep Dutta in 2006 at the Asian Institute of Technology. The technology underwent continuous development until 2017, with in-depth scientific inputs from several scientists, students and researchers. The current product design for sustainable commercial applications was developed and optimized by us in Stockholm, Sweden in collaboration with KTH Royal Institute of Technology. Extensive tests have proved the product to be rugged and commercial prototypes are being validated in various application domains both in Sweden and internationally.
