An electrical power source is connected to two electrodes or two plates (typically iron bar is the anode and an aluminum bar is a cathode) which are placed in the water.
When the power is on, positive ions will appear at the cathode (the negatively charged electrode - iron bar) where electrons enter the water and react to produce a water-insoluble group with negative electrolyte, colloid, organics, or in-organics.
Because of the current, original metal particles dissolved in water, such as lead, arsenic, chromium, manganese, potassium, cobalt, etc. are electrolyzed out and gradually gather into the metal group.
We distinguish different metals based on the shown color, for different metal ions show different colors. Here is the color and chemicals comparison chart below:
