Stockholm Water Technology is a Swedish company specializing in the development of low pressure, low CAPEX energy efficient water desalination systems (patented), which are safe to operate and easy to maintain.


Prof. Joydeep Dutta has been involved in research and development of capacitive deionization technology since 2006. He is currently the Chair of Functional Materials at the KTH Royal Institute of Technology, Stockholm, Sweden. Earlier, he was the Chair Professor in Nanotechnology for Water Desalination and other applications in Sultan Qaboos University (2011- 2015).

He served as the Vice President (Academic Affairs), Director of the Center of Excellence in Nanotechnology and Professor in Nanotechnology at the Asian Institute of Technology (AIT), Bangkok, Thailand, whose faculty he joined in April 2003. He completed his Ph.D in 1990 from the Indian Association for the Cultivation of Science, India (Calcutta University).

After 2 years of post-doc. in Japan and France, he moved to Switzerland in 1993 where he was associated with the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland until 2003. Since moving to Sweden in 2015, he established the Stockholm Water Technology activities and has built up active research and development efforts in his group.


Dr. Karthik Laxman specializes in water desalination using capacitive deionization technology with more than 8 years of related research experience. He has four years of Industrial experience, two of which were in a start-up company as a hardware designer, where he was part of the product development team.

He has a Bachelors degree in engineering with a major in Power Electronics (2005), a Masters in Nanotechnology (2011) and a PhD. in water desalination and disinfection (2015) with a focus on capacitive deionization (CDI) electrode and system architecture.

Since moving to Sweden in 2016, Karthik has been involved in CDI research activities in the group of Prof. Dutta. In 2018, Karthik founded Stockholm Water Technology with Joydeep and has been managing its activities and development.
