What is Demineralized Water Plant

Demineralized water plant, also known as demin plant or deionized water plant, is a type of industrial water treatment system that removes impurities and minerals from water, resulting in highly purified water. This process involves the use of ion exchange resins that bind and remove mineral ions from the water, leaving only hydrogen ions and hydroxyl ions that combine to form pure water.

Application of Demineralized Water Plant

Demineralized water plant is mainly used in industrial applications where highly purified water is required, such as in electronics, pharmaceuticals, power generation, and semi-conductor manufacturing. This type of water plant is also used in laboratories and medical facilities where high-quality water is essential.

Advantages of Demineralized Water Plant

One of the main advantages of demineralized water plant is that it produces water with improved quality and purity. This makes it ideal for use in medical facilities and laboratories where high-quality water is necessary. Additionally, demineralized water plant reduces the amount of minerals and impurities in the water, which in turn helps to prolong the lifespan of equipment that comes into contact with the water.

Operating Principle of Demineralized Water Plant

The operating principle of a demineralized water plant involves the use of two ion exchangers. The first ion exchanger is typically an anion exchanger that binds and removes negatively charged ions such as chloride, sulfate, and nitrate from the water. The second ion exchanger is a cation exchanger that binds and removes positively charged ions such as calcium, magnesium, and sodium.

Once these ions have been removed, the final stage of the process involves a polishing step where any remaining ions or impurities, including trace metals and organic compounds, are removed using a mixed bed ion exchanger. The resulting water is then of high quality and suitable for use in a variety of industrial applications.

Maintenance of Demineralized Water Plant

Maintenance of a demineralized water plant involves regular monitoring of the system and replacement of ion exchange resins. The frequency of resin replacement depends on the quality of the raw water, the volume of water treated, and other factors specific to the application. It is recommended that the system is serviced at least once a year to ensure optimal performance.

In conclusion

Demineralized water plant is an essential component in many industrial applications where high-quality water is required. The process of removing impurities and minerals from water using ion exchange resins ensures that the water is of high purity and suitable for a wide range of applications. Proper maintenance and servicing of the system are important to ensure optimal performance and the long lifespan of the system.
