Working principle of ultra-pure water equipment for monocrystalline silicon production

Thread Content

　　Ultra-pure water equipment for single-crystal silicon production is, as the name suggests, primarily used in the production of single-crystal silicon. This equipment utilizes advanced reverse osmosis and EDI technologies to effectively remove ionic impurities from the raw water, ensuring that the water output meets the requirements for industrial use. 　　Working principle of ultra-pure water equipment for monocrystalline silicon production: 1. Water enters the purification system; the main portion flows inside the resin/membrane, while another portion flows along the outside of the membrane to remove the ions that pass through it. 　　2. Resins retain dissolved ions in water. 【Laitread Nanjing Water Treatment Equipment Company www.nanjingshui.com】 3. Under the action of the electrodes, the trapped ions move towards the positive electrode, while the cations move towards the negative electrode. 　　4. Cations pass through the cation membrane and are discharged outside the resin/membrane. 　　5. Anions pass through the anion membrane and are discharged outside the resin/membrane. 　　6. The concentrated ions are discharged from the wastewater flow path. 　　7. Deionized water flows out from within the resin/membrane. 　　Features of ultra-pure water equipment for monocrystalline silicon production: 1. High degree of integration, easy to expand – increasing the number of membranes can boost the processing capacity. 　　2. It features a high degree of automation; it shuts down automatically in the event of a fault and has an automatic protection function. 　　3. The membrane module is made by rolling composite membranes, resulting in a higher solute separation efficiency and flux rate. 　　4. Low energy consumption, high water utilization rate, and low operating costs. 　　5. It has a reasonable structure and occupies little space. 　　6. An advanced membrane protection system that, when the equipment is turned off, allows the desalinated water to automatically wash away contaminants from the membrane surface, thereby extending its lifespan. 　　7. The system has no vulnerable components, requires little maintenance, and remains effective over a long period of time. 　　8. The equipment is designed with a scale prevention system for the membrane cleaning system. 　　I hope we can learn from each other, discuss together, and make progress as a group.
