Deionized Water: Blank Water and its Benefits

Deionized water sounds complicated but it’s really rather simple. Water that has been deionized has simply had the “ions” removed. It can also be referred to as demineralizing, as ions are minerals or dissolved mineral salts that accumulate in our water.

Two types of ions are removed during the deionization process, positively charged ions called “cations” and negatively charged ions called “anions.” Calcium, magnesium, iron, and sodium are examples of “cations” while chloride, sulfates, nitrates, carbonates and silica are examples of “anions.” Our Culligan deionization products reduce total dissolved solids (TDS) from water by means of ion exchange resins. This complex process results in high-purity water from a system that is easy to use and maintain.

In a process called ion exchange, resin beads that have positive or negative charges attract the minerals of the corresponding electrical charge which bind to them until the ions are removed from the beads and flushed from the system in a process called regeneration using caustic acid.

At Culligan, we also have a system that uses a process called continuous electro-water deionization. Electrodeionization (EDI) systems are an environmentally friendly technology that utilizes small amounts of electricity, no harsh chemicals, along with ion exchange membranes and small amounts of resin to deionize the water.

Deionized water is water in its purest form and basically blank water. As such, deionized water will take on the chemistry of whatever is added to it. This makes it undesirable as a drinking water because it can absorb the minerals in your body and take on toxic metals that it comes in contact with.

Because deionized water is water that is free of all ions and electrical charge, it’s the ideal water for medical manufacturing and biotech and pharmaceutical industries. Deionized water is necessary for these companies’ products to ensure that no minerals or bacteria exist in the water being used in products, removing the risk of adverse chemical reactions and providing a pure product. Deionized water is used in glass manufacturing to avoid the buildup of mineral deposits on the glass and in factories to avoid salt buildup on machines, as well as a cooling agent for equipment. Cosmetics and food manufacturing also often use deionized water in their products. The commercial uses of deionized water are endless and it’s used in just about every industry including oil and gas and energy and power.
