(STEP 1) Minerals are the major components of TDS (total dissolved solids).These minerals need to be removed on many applications, or they will form deposits. The CDI Desal Water Purifier makes patented technology available to generate a de-ionised quality water. Electrodes used are made from activated carbon and other materials. These electrodes are layered into a cell casing. DC power is applied across the electrodes. The individual electrodes are charged with different polarities.
(STEP 2) Minerals in water have polarity charges, and 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 go through regeneration steps.
(STEP 3) The contaminants are repelled from the electrodes when the polarity is reversed and flushed via a valve when the solenoid opens, discharging the contaminants. This completes the cycle.
