What is Di Water?
Di water of Deionized water is basically water that has most of it’s dissolved ions and minerals removed. It is known as an ultra pure water because it is water in it’s pure form with no electrical charge. Many of the ions removed consists of calcium, sodium, and chlorides.
How are ions removed from the water?
Ions are removed from the water through a process called ion exchange. In this process ions with a negative charge attracts ions with a positive charge.
Positively charged ions are known as Cation.
Negatively charged ions are known as Anion.
The exchange of the ions occurs due to the binding of the resins beds in the filter systems. What are resin beds?
Well, its small beads made of polymer substrate and it traps other ions with the process of releasing other ions. Ion exchange resins are mainly used for purification of water and water softening. After the ion exchange process is completed, the resin is regenerated with concentrated acid which helps it remove the accumulated ions. This therefore makes the resin able to continue it’s ion exchange once again.
There are two types of resins:
1. Cation resins – The cation resins have a negative charged ion which attracts positive ions.
2. Anion resins – Anion resins is the opposite, with a positive charged ion, it is attracting the negative ions.
There are two types of filtration systems when it comes to Di water filters.
1. Separate Bed Deionization: In this filtration system, the cation resin and the anion resin are in separate tanks.
2. Mixed Bed Deionization: This filtration have a combination of cation and anion resins in one tank. Because the base anion and cation resins are intermixed, the ion exchange is continuously working over and over again. Thus producing more of a higher and pure di water quality.
What is Di Water Used for?
Deionized water is an essential substance in many fields including medical, laboratory, cosmetics, electronics manufacturing, food processing, pharmaceutical, and even aquariums.
pH of Deionized Water
Most pure water are usually at a neutral ph level of six to eight on the pH scale. Although purified water seems to be acidic, there are varying different elements that can interfere or change the pH of pure water. For example, carbon dioxide in the air can actually lower the pH of water whereas the tongue can actually raise the pH levels. Deionized water is an ultra pure water with no electrical current and has been measured to be a pH of 7 on the pH scale.
How is Deionized water measured?
In order to measure di water, many experts uses a specific type of tool to measure the di water’s pH. This tool is call the pH electrode which consists of a liquid filled tool with low resistance glass.
Is Di Water Safe for Consumption?
Although Di water is not toxic, It is water with no minerals and no electrical charge. It provides no nutrition for the human body and therefore it is not the best choice to choose as a hydrating solution.
Here are some water that are safe for consumption:
