APPLICATION

COMMERCIAL OPPORTUNITIES

  • Remote communities (mobile or stationary); solar powered
  • Individual supply to homes
  • Industrial water clean-up- Towards zero discharge
  • Reverse Osmosis (RO) Brine Treatment for Maximum Recovery- Reduced pollution
  • Mobile disaster and emergency back-up water supply- Life saver
  • Boiler or Cooling Tower Water Conditioning- Avoid scaling
  • Food & Beverage Production Applications- Provide conditioned input water quality
  • Municipal Water Treatment- Multiple uses
  • Hydroponic Irrigation Systems- Remove unwanted ions
  • Laundry Feed Water- No need for salt for softening water

MILITARY APPLICATIONS

  • Small portable desalination units for forward operating bases
  • Mobile applications
  • Waste water clean-up (removal of toxic chemicals)

ENVIRONMENTAL IMPACT 

With energy consumption typically below RO in comparable brackish water applications, CDI ranks on a preferred level of sustainability in brackish water desalination.

PILOT TESTING PROJECTS 

Stockholm Water Technology is pleased to work with you on piloting this technology.  To ensure a custom built solution, Stockholm Water can provide you a cost benefit analysis to showcase advantages of this technology.  In order for us to complete a study, we need the following information from your utilities, maintenance or engineering team:

  • Feed water quality & source;
  • Treatment targets (conductivity, hardness, TDS, temperature, etc.);
  • System capacity (flow-rate requirements);
  • Chemical consumption of existing water treatment system;
  • Unit prices of chemicals used the water treatment process

HISTORY OF THE DEVELOPMENT

The current technology development was started by Prof. Joydeep Dutta in 2006 when he was a member of the Asian Institute of Technology. The technology was improved during 2012-2015 by Dr. Karthik Laxman while doing his PhD dissertation. Another PhD student and several master’s students worked with Prof. Dutta in the development of the current technology that was optimized at KTH with a new design for sustainable commercial applications.

Extensive laboratory tests have proved the product to be rugged and currently large volume prototypes are being developed to be validated in Stockholm. Developments over the last decade has made the current group as one of the Top 5 research groups in the world in capacitive deionization technology and top 30 in the world in Water Treatment.
