DI water treatment system helps create an ultra-pure water source, which is especially important in industries that require absolute precision, typically semiconductor manufacturing.
DI technology demineralized water filtration system helps create an ultra-pure water source, which is especially important in industries that require absolute precision, typically semiconductor manufacturing.
DI (Deionized Water or Deionization Water) water treatment system is an ultra-pure water treatment system, also known as demineralized water treatment system.
DI demineralized water filtration system adopts advanced treatment technology, which eliminates the following components in water: Chlorides, carbon dioxide CO2, and silica (anions), sodium, calcium, and magnesium (cations) Sulfates, alkalinity. As a result, it creates ultra-pure water with low electrical conductivity, meeting the strict requirements in high-tech industries.
A device needs to combine a variety of treatments to create ultra-pure water. DI filters need to combine with RO reverse osmosis filters, ion exchangers, and other filtration technologies.
In the DI system, the input water needs to go through the following stages:
DI demineralization equipment uses the particle exchange technology, which removes unwanted ions from the water (anions and cations). The ion exchange process consists of the following three stages:
1. Cation exchange:
In the cation exchange system, metal ions polluting water such as Na +, Ca2 +, Mg2 +, Fe3 + ... are removed.
The removal process takes place as follows: When water is fed into the cation exchange device, the ion exchange resins absorb and retain the metal ion component, simultaneously, releasing H + ions into the water.
In summary, the following cation exchange system has occurred:
R’H + Ca2+ = R2Ca + H+
R’H + Mg2+ = R2Mg + H+
2. Anion exchange
Anion exchange system eliminates unwanted anions in water, maybe Cl–, SO42-, NO3–, CO32-, SiO2–,…. While these anions are absorbed by resins, OH- ions are released into the water.
After that, OH- ions combine with H + ions in the cation exchange system to form H2O water molecules.
3. Mixed Bed exchange system
The Mixed Bed exchange system contains anion and cation exchange particles at a certain ratio to eliminate unwanted negative and positive ions from the water again, helping to create a source of pure finished water, no more polluting ions, resistivity only 10 - 18 MΩ ∙ cm, low electrical conductivity.
Note: The process of desalination in water can be performed continuously and more cost-effectively by using EDI equipment. Learn more about EDI water treatment systems here.
Ultrapure water is a term used to refer to water that has "high purity" and low conductivity. All contaminants present in water, such as dissolved, volatile, dissolved gases, dissolved ions, inorganic or organic in water, must be removed.
The DI water treatment system removes most of the metal ions, minerals, and dissolved salts in the input water, creating ultra-pure water. Therefore, DI plays an important and indispensable role in many industries that need absolute accuracy, especially the semiconductor manufacturing industry and a number of other industries.
Here are some applications of the DI water treatment system in life:
Investing in DI demineralized water supply system is an economical reasonable solution to have abundant pure water sources for long-term production activities. Based on the quality of feed water and user requirements, the DI water treatment system can be customized.
