Ionized Water Filters

Ionized water filters are a very important type of water filters, which use the chemical process of ionization to purify the water and enable it for drinking. Water is electronically altered by being run over positive and negative electrodes. The water is ionized and separated into alkaline and acidic water. Both waters have excellent properties. The alkaline ionized water is a great antitoxin for the body and is used for drinking. The acidic ionized water is usually used for bathing as it is very good for killing bacteria. Usually for a given volume of water, 70% becomes alkaline water and 30% becomes acid water.

Ionized water filters are readily known as Water Ionizers. They usually perform two functions, filtration and ionization. Filtration is used to remove harmful contaminants from the water. Ionization process separates the water molecules and the minerals present in the water, into positive and negative ions.

Stage One: Filtration
During the stage of filtration, the water ionizers filter out some very dangerous and harmful contaminants from water using a combination of bacteriological and particulate control, incorporating silver activated charcoal, the most accepted and proven method on the market. The following contaminants are removed during the first stage:

Bacteria	Tri-halomethanes
Inorganic Chemicals	Lead
Organic Chemicals	Particulate
Pesticides	Volatile Organic chemicals
Detergents	Asbestos
Viruses	Pollens

However the soluble minerals don't get filtered in this process. Unlike distillers or reverse osmosis devices, the water have minerals in it. Now it is the job of ionizer to purify, (soluble) mineralized water.

Stage Two: Ionization
Ionization is occurred through a process called electrolysis. It takes place in the electrolysis chamber that is partitioned into two compartments by a diaphragm or membrane. There is a positive electrode in one chamber and a negative electrode in other one. A very specific low voltage electric current is passed through the water, which causes the soluble minerals to be attracted to either of the poles ( positive or negative). The electrolytic process causes the water on one side to become alkaline, and the water on the other side to become acidic.

The electric current flown through the water dissociates water molecules into hydrogen (H+) and hydroxide (OH-) ions. More number of H+ ions than OH- ions, makes the water acidic. While more number of OH- ions makes the water alkaline. The same no. of both means the water is neutralized.

Near the negative electrode, the H+ ions acquire electrons and are neutralized thus increasing the number of OH- ions and making the water alkaline. Near the positive electrode, the OH- ions release electrons and consequently increase the number of H+ ions resulting in making the water acidic. Within the electrolysis chamber, the negative electrode or anode attracts the positively charged minerals (like beneficial Ca+, Mg++, etc) to its compartment making the water alkaline. The positive electrode or cathode attracts the negatively charged minerals (like Cl-, F-, etc) ending in the acidic water.

Alkaline & Acidic Water

• Alkaline and acidic water are the two main products of ionized water filters. Both of them are useful for us and they find different applications.
  
  
• Alkaline water is used for drinking, it has been proved worthy in reducing acid symptoms and increasing health.
  
  
• Acidic water is used externally, for skin, healing, plants and disinfecting. It is used for dermal application. It is also used for household cleaning as it is a powerful antiseptic.
  
  
• The most interesting thing of this process is that the minerals, that flow out with the alkaline water are all advantageous for us, while the minerals that flow out with the acidic water are not.
  
  
• They are used in a large number of hospitals and clinics, both for consumption and wound healing, in place of costly drugs.
