Product Description:

Electrodeionization (EDI) equipment is a cutting-edge water treatment technology that combines the benefits of reverse osmosis and electrodeionization to produce high-purity water. EDI utilizes an electric field to encourage ion migration and selectively extracts dissolved ions in water to achieve high deionization. This technology offers a chemical-free regeneration process, reduces the use of chemical reagents and environmental impact, making it perfect for industrial applications that need ultrapure water.

Working Principle:

The EDI process has four phases:

1. Influent pretreatment: First, the raw water is treated with reverse osmosis to remove a majority of dissolved solids and impurities.
2. Membrane separation: The second step involves efficiently separating and extracting cations and anions with selective membranes such as cationic and anionic membranes. This method significantly improves the effluent water's purity.
3. Electric field action: Then, a voltage is applied to the EDI unit, creating an electric field between the positive and negative electrodes promoting cations to migrate to the cathode and anions to migrate to the anode.
4. Wastewater discharge: Finally, the separated ions and impurities discharged through the concentration chamber keep the system clean and efficient.

Product Function:

The EDI technology's outstanding features include:

• Efficient deionization: EDI technology effectively extracts cations and anions in water, satisfying the ultrapure water standards.
• Chemical-free regeneration: The usage of chemical agents is avoided in the EDI regeneration process, reducing environmental pollution and operating costs.
• Real-time monitoring: Equipped with a water quality monitoring system to track water quality changes in real-time.
• Automatic control: EDI technology uses an intelligent control system to provide automated operation and improve the stability of the system's operation.

Technical Parameters:

There are several factors that can have a significant impact on the efficacy of a given process or system, but perhaps none are more impactful than influent conductivity. This measure relates to the ability of the influent (i.e. the substance being treated) to conduct electricity, and can vary widely depending on the specific characteristics of that substance. The influent flow rate is another critical factor to consider, as it can affect everything from the overall efficiency of the process to the specific details of how various components within the system interact with one another.

Alongside these electrical and fluidic factors, it's also important to consider basic physical parameters such as voltage and current, which can greatly affect the overall performance and stability of the system. Additionally, influent pH levels can also play a key role in determining the success or failure of a treatment or processing setup. Other factors that should be taken into account include temperature and pressure, which can have significant impacts on the overall efficiency and safety of a given process or system.

Applications:

The electronics industry requires ultrapure water for semiconductor manufacturing and cleaning processes. This is because impurities in water can cause damage to delicate microelectronic components, leading to costly production errors and compromises in product quality.

The pharmaceutical industry also demands high levels of water purity to ensure the safety and efficacy of their products. Water is used in various production processes, including as an ingredient in drugs and for cleaning equipment. Any contaminants in the water can jeopardize the effectiveness of drugs or cause adverse effects in patients.

Laboratories and scientific research institutions rely on stable experimental water to support high-precision experimental needs. The quality of water used for experiments can directly affect the accuracy and reproducibility of scientific outcomes. Therefore, it is important to provide researchers with reliable and consistent sources of experimental water.

The chemical industry requires advanced water treatment technologies to treat wastewater and recycled water. This is necessary to support compliance with environmental regulations and minimize negative impacts on the environment and human health. Advanced water treatment technologies can remove hazardous chemicals and pollutants, making the treated water suitable for reuse or safe release into the environment.

In the power industry, high-quality water sources are required for boiler feed water and cooling systems. Poor water quality can lead to corrosion and scaling of equipment, resulting in reduced efficiency and increased maintenance costs. It is essential to provide power plants with high-quality water sources to maximize energy production and ensure reliable operations.
