Product Description:

Electrodeionization (EDI) equipment is a cutting-edge water treatment technology that adopts the benefits of reverse osmosis and electrodeionization to prepare high-purity water. EDI utilizes electric fields to move ions and selectively membranes to remove dissolved ions in water which leads to high deionization. With this state-of-the-art technology, chemical regeneration is not necessary hence reducing chemical reagent use and environmental impact. It is the perfect solution for ultrapure water demands in various industrial applications.

The Working Principle of EDI:

There are four stages in the Electrodeionization System:

1. Influent Pretreatment: In this stage, the raw water is purified through the process of reverse osmosis, getting rid of impurities and dissolved solids.
2. Membrane Separation: In EDI, cations and anions are effectively removed, thereby improving the standard of the effluent water quality through selective membranes (cationic membranes and anionic membranes).
3. Electric Field Action: Once voltage is applied to the EDI system, an electric field is generated between the positive and negative electrodes in the unit. This causes migration of cations to the cathode and anions to the anode of the system.
4. Wastewater Discharge: In this final stage, the removed impurities and ions are discharged through the concentration chamber, thus ensuring the system is always efficient and clean.

The functions of EDI System include:

• Efficient Deionization: The water treatment technology can effectively remove cations and anions to produce ultrapure water that meets appropriate standards.
• Chemical-free Regeneration: Unlike other systems, the EDI system reduces environmental pollution and operating costs by avoiding the use of chemical agents.
• Real-time Monitoring: The EDI system is equipped with a water quality monitoring system to monitor water quality changes in real-time.
• Automatic Control: The system is conveniently automated using an intelligent control system, providing system stability and offering seamless operation.

Technical Parameters:

The main factors that have an impact on a system are its influent conductivity, influent flow, voltage and current, influent pH, and temperature and pressure. These factors can greatly affect the performance and efficiency of the system. Therefore, it is important to constantly monitor and adjust these factors to ensure optimal performance.

The influent conductivity refers to the ability of the influent to conduct electricity. This factor can greatly affect the efficiency and effectiveness of the treatment process, as high conductivity can lead to increased fouling and scaling, which can reduce the lifespan of the system. To address this, the system should be equipped with appropriate filtration and chemical treatment processes.

The influent flow rate is another crucial factor that can affect the system's performance. A consistent and appropriate flow rate is essential to ensure optimal treatment and avoid clogging or blockage in the system. The system should have flow meters and sensors to monitor and control the flow rate.

Other factors such as voltage and current, pH level, temperature, and pressure can also have significant impacts on the system's performance. Proper controls and monitoring systems should be in place to detect and address any potential issues in these areas. Regular maintenance and calibration of the system are also essential to ensure its optimal performance.
