CapDI Voltea CapDI Membrane Capacitive Deionization

We specialize in tunable water purification  that is designed to removetotal dissolved salts (TDS) from a variety of water sources, ranging fromtap water and brackish groundwater to industrial process water. CapDIachieves this at a lower economic cost and reduced environmentalimpact than any other available technology. Voltea’s CapDI technology treats water types ranging from residentialconsumer appliances to large-scale industrial plants. Our systems aremodular, allowing easy expansion to meet any increased water demands.
