EDI equipment uses electrochemical reaction and ion exchange technology to further remove ions and organic substances in water through electrodes and ion exchange membranes. In the entire water treatment equipment, the EDI equipment is located at the back end of the reverse osmosis (RO) system, followed by the mixed bed (Mixed Bed) resin. This location is critical to delivering high-purity water quality, and the EDI equipment plays a central role in the pre-desalination process.
EDI equipment has several advantages:
● High-purity water quality: EDI equipment can remove ions and organic substances from water, providing high-purity water quality to ensure that your production and experimental processes are not polluted.
● Easy operation: EDI equipment does not require the use of chemical regenerants, is relatively simple to operate, can operate continuously, and can achieve automated control, reducing the complexity of operations.
● High efficiency and energy saving: Compared with traditional ion exchange methods, EDI equipment has higher efficiency and lower energy consumption, saving energy and costs.
● Environmentally friendly: The EDI process does not require the use of chemicals, reducing environmental pollution and complying with environmental protection requirements.
EDI equipment is widely used in various fields:
● Electronics, semiconductor and photovoltaic industries: In these industries, high-purity water is an indispensable resource in the production process. EDI equipment can remove trace amounts of ions and organic substances from water to ensure product quality and performance.
● Pharmaceutical industry: In the pharmaceutical process, the requirements for high-purity water are very strict. EDI equipment can provide pure water that meets pharmacopoeia standards to ensure the safety and purity of pharmaceuticals.
● Electric power industry: In boiler feed water treatment, EDI equipment can remove ions in the water, prevent scale and corrosion, and improve the efficiency and life of the boiler.
● Laboratory and Medical Facilities: In laboratory research and medical facilities, high purity water is a must. EDI equipment can provide high-purity water quality for experiments and analysis, ensuring the accuracy and reliability of experimental and medical operations.
We recommend EDI equipment to you, which can provide high-purity water quality, is easy to operate, energy-saving and environmentally friendly, and is suitable for electronics, pharmaceuticals, electric power, laboratories and other industries. Our EDI equipment is carefully designed and optimized to meet your water treatment needs and provide you with high-quality service and products.
