Voltea commercializes Capacitive Deionization (CapDI) in a number of applications, ranging from industrial water re-use to residential water softening. CapDI is the world’s most efficient system to desalinate brackish water.
Voltea’s CapDI technology has been recognized by numerous awards including best new technology award at the 2010 Global Water Summit, most creative company in Europe by CNBC and The Artemis Top 50 of water technology companies 2011.
In CapDI, water flows through a small electrical field of 1.5 volts that is created by a pair of electrodes. Dissolved ions are pulled out of the water stream, toward the electrodes. The electrodes are separated from the water by membranes that selectively allow only positive or negative ions to pass. CapDI is effective at removing all type of ions from water (e.g. calcium, sodium, chloride, sulfate, carbonate…).
* Step 1. Purification:<br>
The concentrated brine between the two membranes is flushed from the system. The charge of the electrodes is returned to normal and the system is again ready to desalinate.

CapDI typically recovers between 80% and 90% of the water it treats, compared to 50-70% for reverse osmosis. This is good for the environment and can save costs, both in overall water intake and in brine water discharge.
===Operations and Maintenance===
Voltea’s CapDI systems are based on a single technology platform, which allows for variable salt removal, and is scalable across water volumes ranging from a few milliliters per minute to thousands of cubic meters per hour. This
flexibility means CapDI can be used in a wide array of applications, from residential white goods to large industrial cooling towers.
Unlike competing desalination technologies, CapDI does not require any chemicals such as biocides or anti-scalants.
====Test resultsResults==== [[Image:test result.png|thumbnone|600px|Arsenic level is below Bangladesh standards its only 0.021 mg/L, but not only the As but also the others parameters Like Iron, Electrical Conductivity.]]
Test Result 25 July, 2012 if we see below result (P-004)we find that capDI can remove Arsenic From water and it is below Bangladesh Standard only 0.029 mg/L and other Parameters are also within Bangladesh Standard
