Time of issue:2019-04-17
【 Summary Description 】With the continuous spread of modern water pollution, the problem of scale appears in both domestic and industrial water. Many companies introduce ultrapure water equipment to improve water quality, but scale still appears after a period of use. What is the reason? Today, let's learn about how to solve the problem of scale in ultrapure water equipment. 1. Remove some scale-forming ions. The scale-forming ions of calcium carbonate scale are calcium and carbonate (converted from bicarbonate) ions. When the calcium ions and alkalinity are high in the supplementary water, part of the hardness and alkalinity can be removed in the pretreatment process, which is beneficial to improve the concentration multiple of the circulating water. Common softening methods include ion exchange
With the increasing prevalence of modern water pollution, scale problems are occurring in both household and industrial water. Many companies introduce ultrapure water equipment to improve water quality, but scale still appears after a period of use. What is the reason for this? Today, we will explore methods to solve the problem of scale in ultrapure water equipment.
1. Remove some scale-forming ions. The scale-forming ions of calcium carbonate scale are calcium and carbonate (converted from bicarbonate) ions. When the calcium ions and alkalinity are high in the supplementary water, part of the hardness and alkalinity can be removed in the pretreatment process, which helps to improve 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.
