The Problem

Minerals in the water are the major components of TDS (total dissolved solids). These minerals need to be re-moved on many applications, or they will form deposits. The Electronic Water Purifier makes patented technology available to generate a DI quality water. How it Works Electrodes used are made from activated carbon and other materials. These electrodes are layered into a cell casing. A DC power supply is applied across the elec-trodes. The individual electrodes are charged with differ-ent polarities. The minerals in the water have polarity charges, which are attracted to the opposite polarity of the electrode, thus removing the minerals from the water. These minerals are electrochemically absorbed on the surface of the electrode creating the pure water. When sufficient minerals are deposited on the electrodes and conductivity increases beyond the set point desired, the electrodes are regenerated by shorting the elec-trodes to ground. The contaminants fall off the electrode after a flush valve opens discharging the contaminants removed. Upon completion of this cycle, the polarities are reversed for normal operation.
