Inventors at UW-Milwaukee (UWM) have developed a technology based on capacitive deionization (CDI) that selectively removes lead (Pb2+) from tap water in a single pass mode with zero wastewater emission. This filtration system uses custom made electrodes that allow minimal removal of associated healthy ions (Ca2+ and Mg2+), leaving water safe and healthy for consumption from every tap. Various techniques are available in the market that can be effectively used to remove heavy metal ions from the water, but these methods not only remove unwanted metal ions like Cu, Pb, Cd etc., but also end up removing healthy metal ions (such as Ca2+, Mg2+) in the process. CDI is a water purifying technique that has been less explored in heavy metal ion removal compared to other traditional methods. The lead ion precipitate can be collected using filters equipped in the pipeline, thereby leading to zero‐wastewater generation during the process.
