TECHNOLOGY
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.
Uniquely, CapDI operates at temperatures ranging from 5-60° C, or 40-140° F, on challenging higher turbidity feed waters, with minimal operator intervention. Our technology is environmentally friendly by virtue of 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 – 90% depending on customer needs, eliminating the requirement for blending to achieve a specific water quality. The customer sets their desired reduction rate and CapDI maintains this level, continually adjusting itself to account for any fluctuations in feed water characteristics.
TWO-STEP PROCESS
CapDI is a simple two-step process wherein water flows between electrodes, where the electrode surfaces are separated from the water by ion-selective membranes that allow positive or negative ions to pass.
PURIFICATION
Feed water passes between oppositely charged electrodes which electrostatically remove dissolved ions, leaving pure water flowing out of the cell.
REGENERATION
Feed water flushes through the cell at a lower flow rate, while electrode polarity is reversed. Ions are rejected from the electrode surface, concentrated in the flow channel and flushed from the cell before the cycle is repeated.
