Voltea
Voltea is a water technology company based in Dallas, Texas.
Overview
The company developed Capacitive DeIonization, a desalination method that removes dissolved salts from brackish water. In 2016, the company opened an automated robotic production facility in Texas.Capacitive deionization (CapDI)
Capacitive deionization is an electrical process that combines oppositely charged electrodes with anionic and cationic selective membranes. When salt water flows into the cell between an electric field, the ions move through the selective membranes to the oppositely charged electrodes and desalinated water leaves the cell.When the surface of both electrodes is covered with ions, the electrodes are cleaned by reversing the electrode polarity. The ions are pushed from the electrodes and are trapped between the membranes. The concentrated brine that forms between both membranes can then be removed from the cell. When the polarity of the electrodes is reset to normal, the cell is ready for use again.
In 2017, the company launched a point-of-use device named DiUse. The device is self cleaning and delivers no-salt water softening and low cost brackish water desalination. The device is internet enabled and can be remotely monitored and controlled.
In 2018, Voltea launched a point-of-entry device named DiEntry for whole-home water treatment.
