How to prevent scale formation in ultrapure water equipment?

With the increasing prevalence of modern water pollution, scale problems are occurring in both household and industrial water supplies. Many companies introduce ultrapure water equipment to improve water quality, but scale still forms after a period of use. What is the reason for this? Today, we will explore methods for resolving scale formation in ultrapure water equipment.
　　1. Remove some scale-forming ions. The scale-forming ions in calcium carbonate scale are calcium and carbonate (converted from bicarbonate) ions. When the calcium ion and alkalinity are high in the supplementary water, part of the hardness and alkalinity can be removed in the pretreatment process, which helps to increase the concentration factor of the circulating water. Common softening methods include ion exchange and lime softening.
　　2. Add acid or carbon dioxide to lower the pH of the circulating water and stabilize the bicarbonate.
3. Add a small amount of scale inhibitor to the circulating water to disrupt the crystal growth of scale-forming salts such as calcium carbonate and prevent scale deposition.
