3 VOLTEA CAPDI -MEMBRANE CAPACITIVE DEIONIZATION
The CapDI system uses Capacitive Deionization technology and its function is the removal of ions from the
water.
NOTE: The CapDI system does not disinfect water.
CapDI:A tunable water deionization technology that is designed to remove dissolved salts from a variety
of water sources ranging from tap water and brackish groundwater to industrial process water. CapDI
achieves this at a lower economic cost and reduced environmental impact than any other available
technology.

7
A CapDI module consists of a housing which contains multiple stacks of parallel unit cells. Each unit cell
consists of two porous carbon electrodes separated from each other by a spacer. On top of the electrodes,
ion exchange membranes are placed. The spacer between the membranes acts as a flow channel to
transport the water to be desalinated.
The water flows through a small electrical field of approximately 1.5 volts that is created over a pair of
electrodes. Dissolved ions are pulled out of the water stream, toward the electrodes. The electrodes are
separated from the water by the 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, carbonate).
Uniquely:Our technology is environmentally friendly by its low energy consumption and minimal to no
chemical usage. Thus, allowing any unrecovered water to flow back into the ecosystem safely.
Scalable: Voltea’s technology treats water types ranging from residential consumer appliances to large-
scale industrial plants. Our systems are modular, allowing easy expansion to meet any increased water
demands.
Tunable: CapDI is tunable, allowing adjustable TDS reduction between 25% - 95% depending on customer
needs. Eliminating the requirements for blending to achieve a specific water quality. The customer sets
their desired reduction rate and the CapDI maintains this level, continually adjusting itself to account for
any fluctuations in feed water characteristics.
4 DIUSE
Voltea’s miniaturized version of the CapDI systems, specifically made for the point-of-use applications.
DiUse softens and desalinates brackish water for homes and businesses at an advantage to traditional
desalination technologies due to it being a salt-free, chemical-free alternative. DiUse is ideal for the
HoReCa industry alongside small households.
