**Product Information:**
This small deionization equipment is designed to meet the needs of users by achieving water quality that complies with industry standards (0.1-18 MΩ·cm). The system is engineered to minimize contamination at each stage, thereby extending the lifespan of the equipment and reducing maintenance efforts for operators. The process begins with municipal tap water as the source, which goes through a series of pretreatment stages, including a media filter, activated carbon filter, sodium ion softener, and precision filter. This is followed by a reverse osmosis (RO) unit, and then a mixed bed ion exchange or EDI (Electrodeionization) system, ensuring the final water resistance reaches 0.1–18 MΩ·cm. Deionized water can be classified into different grades based on its conductivity: - **Class A**: Conductivity typically ranges from 200 to 10 μS/cm, suitable for general purification. - **Class B**: Conductivity is usually between 1–10 μS/cm, meeting food-grade standards and can be consumed directly. - **Class C**: Conductivity is around 0.1–0.9 μS/cm, used in fine industrial applications. - **Class D**: Conductivity is above 0.06 μS/cm, commonly used in electronics and microelectronics industries. This type of equipment is widely used in sectors such as microelectronics, semiconductor manufacturing, power generation, pharmaceuticals, and laboratories. It can also serve as distilled water for pharmaceutical use, production water for food and beverages, and boiler feedwater in power plants. The process of producing deionized water typically involves methods like reverse osmosis, ion exchange, mixed bed, electrodialysis, distillation, and EDI. Each method has its own advantages and is selected based on the required water quality and application. **Principle of Mixed Bed Deionization Equipment:** This system uses both anion and cation exchange resins to remove ions from the water. The process involves an adsorption mechanism where ions are exchanged with other ions of the same charge, resulting in purified water. **Principle of EDI Deionization Equipment:** EDI combines electrodialysis with ion exchange technology. It replaces traditional mixed bed systems with an electrically regenerated ion exchange process. Using ion exchange resins and selective ion membranes, it achieves high desalination efficiency. When combined with reverse osmosis, it can produce water with a resistivity of up to 10–15 MΩ·cm. EDI systems can be customized to meet different flow rates, ranging from 0.5 m³/h to 400 m³/h. **Principle of Electrodialysis Equipment:** Under the influence of a direct current field, ions in the water move through ion-selective membranes. The setup consists of alternating cation and anion exchange membranes, creating compartments where ions are removed, leaving behind purified water. This method is effective for desalination, purification, concentration, and refining. **Typical Process Flow:** - **Traditional Process:** Pretreatment → RO → Intermediate Tank → Coarse Bed → Mixed Bed → Pure Water Tank → UV Sterilizer → Polished Mixed Bed → Precision Filter → Final Product (≥18 MΩ·cm) - **Latest Technology:** Pretreatment → RO → Intermediate Tank → EDI Unit → Pure Water Tank → UV Sterilizer → Precision Filter → Final Product (≥15–18 MΩ·cm) These systems ensure consistent, high-quality deionized water tailored for various industrial and commercial applications.
