EDI power rectifier is a power equipment that converts AC power into DC power through rectification, providing stable power supply for electronic devices. This type of power rectifier is commonly used in various electronic devices and instruments that require DC power. For example, in ultra pure water equipment, the CEDI membrane stack requires a DC power rectifier to supply power.

CEDI electro deionization membrane stack is a type of electro deionization technology that achieves deep purification of water quality by combining electric fields and ion exchange membranes. The following is a detailed introduction to the CEDI electrodeionization membrane stack:
1、 Working principle
The CEDI electro deionization membrane stack is mainly composed of three layers: electrode plate, ion exchange membrane, and diffusion dialysis. Under the action of an electric field, water molecules move from the anode to the cathode through an ion exchange membrane, while positively charged cations and negatively charged anions are attracted by the fixed charges on the membrane and adsorbed on its surface. Over time, ions gradually penetrate into the deep layers of the membrane under the action of an electric field and are exchanged and removed.
2、 Characteristics
High purification efficiency: CEDI electro deionization membrane stack has efficient purification ability, which can effectively remove harmful substances such as dissolved salts, organic matter, heavy metal ions, etc. in water, ensuring the quality of effluent water.
Low energy consumption: The energy consumption of CEDI electrodialysis membrane stack is relatively low, only about one-third of that of traditional electrodialysis technology, reducing operating costs.
Environmental Protection: The CEDI electro deionization membrane stack uses physical methods for water treatment without the use of chemical agents, avoiding environmental pollution. At the same time, this technology can also achieve the resource utilization of wastewater, which is in line with the concept of sustainable development.
Easy to maintain: The CEDI electro deionization membrane stack has a simple structure, is easy to operate, and is easy to maintain and upkeep.
3、 Application Fields
The CEDI electro deionization membrane stack is widely used in the following fields:
Drinking water treatment: It can be used to prepare high-purity and high-quality drinking water, meeting people's requirements for healthy drinking water.
Industrial water treatment: can be used for industrial circulating water, boiler feed water and other occasions to improve water quality, prevent scaling and corrosion.
Wastewater treatment and reuse: It can be used to treat various industrial wastewater, domestic sewage, etc., realizing the resource utilization of wastewater and reducing the pressure on the environment.
Desalination of seawater: It can be used to desalinate seawater and solve the problem of water scarcity.
4、 Advantages and Disadvantages of CEDI Electrodeionization Membrane Stack
Advantage:
Efficiently remove harmful substances such as dissolved salts, organic matter, and heavy metal ions to ensure effluent quality.
Low energy consumption and lower operating costs.
Environmentally friendly and pollution-free, in line with the concept of sustainable development.
Simple structure, easy to maintain and upkeep.
It can achieve the resource utilization of wastewater and reduce the pressure on the environment.
Shortcoming:
The water quality requirements for the incoming water are high, and pre-treatment is needed to meet the requirements of the CEDI electro deionization membrane stack.
The ability to remove ions is limited and may not meet the high standards required in certain specific situations.
Membrane stacks are prone to contamination and blockage, and require regular cleaning and maintenance.
5、 Future Development Prospects
With the continuous improvement of water quality requirements and the increasing scarcity of water resources, CEDI electro deionization membrane stack, as an efficient and environmentally friendly water treatment technology, has broad application prospects. In the future, this technology is expected to make breakthroughs in the following areas:
Research and development of new membrane materials: Research and develop ion exchange membrane materials with superior performance, stronger pollution resistance, and longer lifespan to improve the purification capacity and stability of membrane stacks.
