Introduction
In-depth interpretation of the national standard for high-salt water concentrating electrodialyzers
This standard (GB/T 43089-2023) specifies the classification, marking, requirements, test methods and inspection rules for high-salt water concentrating electrodialyzers, and is applicable to the design, production and inspection of high-salt water concentrating electrodialyzers.
Comparison of standard frameworks
| Chapter | Main content | Scope of application | Importance |
|---|---|---|---|
| 1 Scope | Specifies the scope of application and basic requirements of the standard. | Applicable to the design, production and inspection of all high-salt water concentrating electrodialyzers. | Basic content to ensure standard uniformity. |
| 4 Classification and Labeling | Classification according to membrane type and structure, and stipulates labeling rules. | All products must be classified and labeled according to standards. | Regulate market circulation and use. |
| 5 Requirements | Includes technical requirements such as appearance, performance, and leakage control. | Ensure that product quality and technical level meet national standards. | Core chapter, directly affecting the application effect of the product. |
Explanation of professional terms and actual cases
Cell pairs: basic working units composed of anion membrane, fresh water baffle, cation membrane and concentrated water baffle in sequence.
Membrane stack: A basic electrodialysis unit composed of several ion exchange membranes, baffles, and water distribution plates arranged in an orderly manner.
Actual application case: In a high-salt water treatment project in a chemical plant, a homogeneous membrane electrodialyzer (DS-J-50-120) was used for concentration treatment, with an effective area of $50\times10^{-2}\mathrm{m^{2}}$, and a total of 120 pairs. During operation, the current efficiency reached 85%, and the unit processing capacity was 450 g/(h·m²), meeting the A-level performance requirements.
Standard formulation background and technology evolution analysis
With the increasing demand for industrial wastewater treatment and seawater desalination, high-salt water concentration technology has become an important direction for water resource utilization. This standard is based on the development status of electrodialysis technology at home and abroad, combined with the pain points in actual applications, and aims to improve the technical level and reliability of the equipment.
Implementation suggestions
- Design phase:Strictly follow the standard requirements to design the membrane stack structure to ensure that the effective area and the number of membrane pairs are reasonably matched.
- Manufacturing:Strengthen quality control, especially appearance inspection and leakage test, to ensure that the product meets the requirements of 5.2 and 5.3.
- Test verification:Test indicators such as current efficiency and unit processing capacity according to the test methods specified in the standard to ensure that the performance meets the requirements.
- Application promotion:Combined with the needs of different industries, develop customized electrodialyzers to expand the scope of application.
