In 2006 EMF joined the Voltea team, a Unilever Venture based company, which was working on a new desalination technology, now known as Capacitive deionization (CapD-I). The CapD-I technology, invented by Marc Andelman in the USA, is removes ions (i.e. dissolved salts such as sodium, calcium, chlorine, nitrate and arsenic) from a variety of water sources ranging from tap to brackish ground water. The technology uses little electricity, has high water recovery a nd does not need any chemical regeneration. In 2012 Voltea is set to enter the market place in Europe and USA for industrial and commercial applications.

Capacitive deionization (CapD-I)

Voltea has developed a unique and simple way to obtain clean, desalinated water with low energy consumption, no added chemicals and a high water recovery rate. This award-winning platform technology – Capacitive deionization (CapD-I) – has numerous applications, from water softening in domestic appliances to treatment of water used in industrial processes. Read how the Cap-DI works.

Competitive

Voltea's technology is flexible and economic, helping consumers and industry reduce water usage and save money.

Flexible

Voltea’s CapD-I systems are based on a single technology platform that has numerous applications. Voltea’s systems require minimal pretreatment of input water, allow for variable salt removal, and are scalable across water volumes ranging from a few millilitres per minute to many cubic metres per hour.

Economic

Voltea’s technology uses much less energy than desalination systems and has higher water recovery than competing technologies, enabling users to reduce water consumption significantly. Voltea CapD-I systems reduce or eliminate the need for chemicals to prevent scaling and biofouling.

Trials in Bangladesh

In 2012 Voltea is set to enter the market place in Europe and USA for industrial and commercial applications and in Asia for village use, as in Bangladesh. Read more about the Bangladesh project.

Investment Funds for Water and Sanitation: Y/N?

Social impact investing is on the rim to become main streamed, this will take another 3-5 years, but the trend is clear: more and more high net worth individuals prefer to invest instead of donate, taking a more business wise approach.
