Product details

1. Plate base material: Gr.1

2. Plate coating: ruthenium series, and adding rare and precious metals to maximize the activation of the coating

3. Process: The coating is configured in strict accordance with the confidential formula, brushed, dried and sintered in a certain order. After brushing, the sampling is strictly tested according to the anode rapid life measurement method to ensure the normal operation of the electrode plate under harsh conditions.

4. In order to ensure the safety of operation and prevent the terminal from being corroded by the material liquid, the terminal is made of titanium-clad copper, which has good electrical conductivity, safety and reliability.

5. Specifications: The size can be customized according to the actual situation of the electrodialyser.

6. The anode can be designed to be reversed, which can automatically clean the dirt formed on the surface of the ion exchange membrane and the electrode, and improve the operating current of the electrodialysis and the recovery rate of water. At the same time, it also has lower overpotential, has power saving performance, and has a longer service life than ordinary ruthenium-iridium-coated metal anodes.


The principle of electrodialysis desalination:

Desalination of seawater by electrodialysis is achieved through electrodialysis desalinators. Specifically, under the action of an external DC electric field, when the raw water containing salt flows through the compartment composed of anion and cation exchange membranes and separators, the anions and cations in the water begin to move directionally, the anions migrate to the anode direction, and the cations migrate to the cathode direction. Due to the selective permeability of the ion exchange membrane, the fixed exchange group of the cation exchange membrane (referred to as the cation membrane) is negatively charged, so it allows the cations in the water to pass through and blocks the anions. The fixed exchange group of the anion exchange membrane (anion membrane for short) is positively charged, therefore, the anions in the water are allowed to pass through and the cations are blocked, causing the ions in the fresh water compartment to migrate to the concentrated water compartment, so as to achieve the purpose of desalination.


Application range:
Electrodialysis devices have been widely used in electric power, chemical industry, electronics, environmental protection, medicine, textile, food and other industries, and have achieved satisfactory economic benefits. The specific uses are:
1) Desalination of seawater and brackish water to produce drinking water.
2) Preparation of beverage water such as beer, soda, purified water, etc.
3) Preparation of low-pressure boiler water.
4) Electrodialysis and ion exchange are combined to produce distilled water, high-purity water and ultra-pure water. This water-making method can save 80-90% of acid and alkali, avoid frequent regeneration of resin, and greatly reduce the cost of water production.
5) Combined with other different processing units, it can be used to make water for industries such as electronics, medicine, food, and chemical industry.
6) Au, Ag, Cu and other precious metals in industrial wastewater (liquid) such as electroplating and electronics
