Are you facing any of these concerns regarding the stable supply of high-quality pure water in boiler systems? - The effectiveness of the ion exchange resin currently in use is gradually declining, leading to an increase in the conductivity of softened water. - Although the resin regeneration is set to occur automatically, there is a risk that starting regeneration during operation could impact production, so we want to control the timing of regeneration. By replacing used ion exchange resin and consumable parts and adding a timer control function, it becomes possible to ensure a stable supply of high-purity softened water. ◇ Scale formation in the boiler is reduced, improving heat transfer efficiency. ◇ The quality of steam stabilizes, allowing for smooth supply to heating equipment. ◇ As a result, thermal efficiency increases, leading to a reduction in fuel consumption. ◇ The stable operation of the equipment also enhances the overall reliability of production. We are currently offering free case studies on boiler systems that support manufacturing lines.

■What is the difference between pure water and ultra-pure water in terms of purification methods? Pure water refers to water that has undergone treatment to remove impurities from tap water, while ultra-pure water is further purified using a combination of reverse osmosis membranes, ion exchange resins, activated carbon, ultraviolet light, and ultrafiltration membranes, enhancing its specific resistivity to 18 MΩ·cm or higher. ■Why is 18 MΩ·cm the standard for ultra-pure water? Water ionizes very slightly on its own, so even if impurity ions are reduced to nearly zero, the effects of this ionization remain. Therefore, the theoretical upper limit for specific resistivity is considered to be around 18.2 MΩ·cm, which serves as the standard for ultra-pure water. ■Why is ultra-pure water referred to as "hungry water"? Ultra-pure water contains almost no impurities, making it more likely to absorb surrounding substances, which is why it is sometimes called that. This property is utilized in cleaning processes, allowing for the maximum removal of invisible ions and organic materials, and it is also used in the cleaning processes of precision equipment such as semiconductors.

■What is the difference between industrial water and tap water? Tap water is strictly managed for quality to be safe for human consumption, while industrial water is defined by the quality needed for use in factories. It is not filtered or sterilized, and only the clear liquid after removing sediments is used, making it unsuitable for drinking. However, it is supplied at a lower cost through a separate water supply network from tap water. ■Why was this separate water supply network created? In fact, this system was initiated due to the serious ground subsidence that occurred in various areas when factories excessively pumped groundwater. While the government regulated the extraction of groundwater, it established a dedicated water supply network to provide alternative sources such as river water to factories. This is why it is not subject to the Water Supply Act. ■Where is industrial water actually used? It is utilized in various situations within factories, such as for cleaning machines, cooling iron, and providing water for boilers. Beyond factories, it is also used in a wide range of scenarios, including washing trucks and in thermal power plants.

■What is pure water used for? Pure water is utilized in a wide range of applications, taking advantage of its low impurity characteristics, not only as experimental water in the fields of physics and chemistry but also in the production of boiler water and drinking water. ■Why is pure water suitable for boiler water? Calcium carbonate has the property of becoming less soluble as temperature increases, which causes scale buildup in boilers. Since pure water has impurities like calcium removed in advance, this phenomenon is less likely to occur, making scale residue less common. ■Why is pure water used in physical and chemical experiments? Pure water has the characteristic of being able to dissolve substances effectively due to the absence of impurities. Thanks to this property, it is easy to handle reagents and samples accurately, and the presence of extra components is less likely to affect the results, making it widely chosen as water for physical and chemical experiments.

■Why is the pH of pure water theoretically "7"? Pure water does not contain substances that can be classified as either acidic or alkaline. Water naturally ionizes very slightly, resulting in hydrogen ions that indicate acidity and hydroxide ions that indicate alkalinity being present in equal concentrations, which makes it neutral, or pH 7. ■Why does actual water deviate from pH 7? When substances that indicate acidity or alkalinity dissolve in water, that water will show acidic or alkaline properties. It is known that even pure water, which should theoretically have a pH of 7, becomes slightly acidic when it absorbs carbon dioxide from the air, resulting in a pH of about 5.6. ■How should pure water be handled to remain stable? As mentioned, pure water has a tendency to be influenced by its surrounding environment. When accurate pH values are needed for analysis or experiments, it is important to handle it carefully, such as minimizing exposure to air.

■What is the difference between pure water and tap water? Tap water contains minerals such as calcium and magnesium, chlorine for disinfection, and aluminum used in the purification process. On the other hand, pure water is water from which such impurities (ions and foreign substances) have been removed, and it is theoretically considered safe to drink as it does not contain harmful substances for the human body. ■How is the purity of pure water measured? The purity of water is generally measured by its "specific resistivity," which indicates how difficult it is for electricity to pass through. The fewer ions present in the water, the harder it is for electricity to pass through, so a higher specific resistivity indicates higher purity. Generally, water with a specific resistivity of 18.2 MΩ·cm or more is called "ultrapure water," while water with 0.2 MΩ·cm or more is referred to as "pure water." ■Is it really safe to drink pure water? Some experts point out that because pure water lacks impurities, it has a strong ability to dissolve surrounding substances, which could potentially leach minerals that the body retains. While this is not a medically established theory, it is good to be aware that such views exist.

■What is a softener? A softener is a device that converts hard water into soft water by passing it through an ion exchange resin, which removes hardness components such as calcium and magnesium. These hardness components can crystallize and form scale, leading to reduced heat transfer efficiency in boilers and clogging in pipes. ■What is the mechanism of ion exchange resin? Ion exchange resin is a type of resin that performs ion exchange by capturing ions present in water and releasing the ions it originally holds in exchange. ■Are soft water and pure water the same? Generally, softening using only cation exchange resin replaces calcium and magnesium with sodium, so sodium itself remains in the water. In contrast, by combining cation exchange resin with anion exchange resin, it is possible to produce purer water by removing both cations like calcium and magnesium and anions like chlorine and carbonate found in tap water. ■Summary While softening and purification are similar, their mechanisms are different. It is important to select the right device according to your needs. Please feel free to consult us first.

One of the important processes in electrodeposition painting is the "cleaning and dilution process using pure water." The core pure water system had aged and was due for renewal. However, during the review of the renewal, the following issues arose: - The models proposed by other companies had excessive specifications and were over-specified for the usage amount. - There was an explanation that it was necessary to introduce large equipment to match the pure water regeneration capacity. - It was difficult to renew within the limited budget. On-site, there was a request for "as small and simple as possible, while having sufficient performance." Therefore, we proposed the optimal pure water system based on our investigation. Please refer to the downloadable materials for more details.

The effectiveness of the ion exchange resin is declining! The conductivity of the soft water is increasing! In the boiler equipment that supports the manufacturing line, a stable supply of high-quality pure water is crucial. There has been a challenge where the effectiveness of the ion exchange resin in use on-site is gradually decreasing, leading to an increase in the conductivity of the pure water. Furthermore, although the resin regeneration was set to occur automatically, there were concerns that starting regeneration during operation could impact production, leading to requests for control over the timing of regeneration. For more details, please refer to the downloadable materials.
