Introduction
DM water, also known as Deionized water, is a type of water that has had all mineral ions removed from it. It is commonly used in various industries, including pharmaceuticals, electronics, and laboratories. DM water plants are used to produce this highly purified water. In this article, we will discuss the steps involved in making DM water plants.
Step 1: Pre-Treatment
The first step in making DM water plants is pre-treatment. This involves the removal of suspended solids, organic matter, and other impurities from the water. The most common pre-treatment methods include sedimentation, filtration, and chlorination. These processes remove impurities that could potentially harm or damage the DM water plant system.
Step 2: Ion Exchange
Once the water has been pre-treated, the next step in making DM water plants is ion exchange. This process involves passing the water through a resin bed that contains ion exchange resins. These resins exchange ions in the water, resulting in the removal of mineral ions such as sodium, calcium, and magnesium. The resulting water is highly purified and free from mineral ions.
Step 3: Reverse Osmosis
After ion exchange, the next step in making DM water plants is reverse osmosis. This process involves pushing the purified water through a semi-permeable membrane that removes any remaining impurities. The membrane has microscopic pores that allow only the water molecules to pass through while trapping any remaining impurities. This process creates highly purified water suitable for industrial use.
Step 4: UV Sterilization
After reverse osmosis, the DM water is almost entirely free from impurities. However, it still needs to be sterilized to ensure that it is safe for use. UV sterilization is the most common method used for this purpose. The DM water is passed through a chamber where it is exposed to UV light, which kills any remaining bacteria or viruses present in the water. The resulting water is not only pure but also safe for use.
Conclusion
In conclusion, DM water plants are essential in producing highly purified water suitable for various industrial uses. The process involves pre-treatment, ion exchange, reverse osmosis, and UV sterilization. Each step in the process is critical in ensuring that the resulting DM water is free from impurities and safe for use. These plants are commonly used in various industries, including pharmaceuticals, electronics, and laboratories, where pure water is necessary.
