INTRODUCTION

EDI ultrapure water equipment is a high-tech water treatment device that integrates advanced technologies, aiming to produce water of extremely high purity. It mainly consists of several key components such as the feed water pump, precision filter, reverse osmosis unit, EDI module, ultraviolet sterilizer, and control system.

The EDI module, as the core component, has a complex and delicate internal structure, containing key elements such as ion exchange resins and ion exchange membranes. Through the synergy among them, efficient removal of ions in water is achieved. In terms of appearance, the overall design is compact and reasonable. The equipment comes in various specifications and can be selected according to different water production requirements. Whether it is for small-scale water use scenarios like laboratories or the large demand for ultrapure water in industries such as electronics and pharmaceuticals, the appropriate equipment model can be used to meet the needs. Moreover, it adopts an automated control system, which is easy to operate and can monitor and precisely regulate various parameters during the operation process to ensure stable and efficient production of ultrapure water.

WORKING PRINCIPLE

The working principle of EDI ultrapure water equipment is based on the electrodeionization technology. Firstly, the raw water undergoes pretreatment to remove larger particulate impurities such as suspended solids and organic substances, and then enters the reverse osmosis unit for preliminary desalination treatment, obtaining water with relatively high resistivity.

Subsequently, this water flows into the EDI module. Inside the module, a direct current electric field is applied between the ion exchange membranes and the ion exchange resins. Under the action of the electric field, the ions in the water will migrate towards the corresponding electrodes. Cations move towards the cathode, and anions move towards the anode. The ion exchange resins will continuously adsorb and exchange the ions in the water, causing the ion concentration to continuously decrease. Meanwhile, under the combined action of the electric field force and water flow, the ions will penetrate through the ion exchange membranes and enter the concentrated water chamber for discharge. In the fresh water chamber, through continuous ion migration and exchange, ultrapure water with extremely high resistivity is finally obtained, which contains almost no impurity ions and meets the extremely high requirements for water purity.

MAIN PERFORMANCE AND CHARACTERISTICS

Ultra-high Purity Water Production: EDI ultrapure water equipment can produce ultrapure water with a resistivity as high as 18.2 MΩ·cm (at 25 °C). The content of various ionic impurities in the water is extremely low, which can meet the needs of industries with the most stringent requirements for water quality, such as electronic chip manufacturing and high-precision analytical experiments, ensuring that the production and experimental processes are not interfered with by impurity ions.

Efficient and Stable Operation: Equipped with an advanced automated control system, it can monitor key parameters such as pressure, flow rate, temperature, and water quality during the equipment operation in real time and automatically adjust according to preset values, ensuring that the equipment remains stable during long-term operation, reducing the impact caused by human operation errors or changes in environmental factors, and ensuring the continuous and stable production of ultrapure water.

Environmental Protection and Energy Saving Advantages: Compared with the traditional ion exchange resin method for preparing ultrapure water, EDI ultrapure water equipment does not need to use a large amount of acids and alkalis for resin regeneration, avoiding wastewater discharge during the acid-base regeneration process and potential harm to the environment. At the same time, it also reduces the cost caused by acid-base consumption, which is in line with the current concept of green environmental protection and sustainable development.

Easy to Operate and Maintain: The overall structural design of the equipment is convenient for operation and maintenance. With a high degree of automation, operators only need to perform simple parameter settings and daily inspections. Moreover, in case of a malfunction, the equipment's fault diagnosis system can quickly locate the problem, facilitating maintenance personnel to repair it in a timely manner, effectively reducing the equipment's downtime and improving the utilization efficiency.

Small Space Occupation: Due to its compact and reasonable structural design, under the same water production demand, compared with some traditional complex combinations of water treatment processes, EDI ultrapure water equipment occupies a smaller floor area and is more suitable for installation and use in places with limited space, such as laboratories and clean workshops.

APPLICATION FIELDS AND INDUSTRIES

Electronics Industry: In the field of electronic chip manufacturing, even extremely tiny impurity ions can cause serious problems such as short circuits and performance degradation of chips. The ultrapure water produced by EDI ultrapure water equipment can be used in key process steps such as chip cleaning and etching, ensuring the high quality and high yield rate of chip production and serving as an important foundation for the precision manufacturing of the electronics industry.

Pharmaceutical Industry: In the production of drugs, many processes from raw material preparation to final product packaging require the use of ultrapure water to avoid the impact of impurities in water on the quality, safety, and stability of drugs. EDI ultrapure water equipment can meet the strict requirements for water quality in the pharmaceutical process, providing a reliable water source guarantee for drug research and development and production, and helping to improve the quality and efficacy of drugs.

Laboratory Analysis: In various high-precision chemical analyses, biological experiments, and scientific research tests, ultrapure water is needed for preparing reagents, rinsing experimental utensils, etc., to ensure the accuracy and reliability of experimental results. The high-purity water produced by EDI ultrapure water equipment can meet the strict requirements of laboratories in different disciplinary fields for ultrapure water and facilitate the smooth progress of scientific research work.

Power Industry: In the processes of thermal power generation and nuclear power generation, the water quality requirements for boiler make-up water and other aspects are extremely high. The ultrapure water produced by EDI ultrapure water equipment can effectively prevent problems such as scaling and corrosion inside the boiler, improve the operating efficiency and service life of power generation equipment, and ensure the safe and stable production of electricity.

Cosmetics Industry: In the production process of cosmetics, ultrapure water is used for dissolving and mixing raw materials and other processes. It can prevent chemical reactions between impurities in water and cosmetic ingredients, ensure the quality, stability, and effectiveness of products, making cosmetics safer and milder and meeting the high-quality market demand.
