A Water Ionizer is a home appliance which claims to raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components. The alkaline stream of the treated water is called alkaline water. The ionizers use electromagnetism to separate the positively charged minerals from the negatively charged bicarbonate. Water ionizers have charged plates, which act just like magnets, they attract the ions that have the opposite charge they do. When that happens, the ions pass through a membrane called a Bipolar Exchange Membrane. The ionizer features titanium and platinum plates. These exchange some of the platinum and titanium ions with the water. The offered Water Ionizer is very efficient and useful.
