What are the main indexes of polyferric sulfate in national standard?
National standard for polyferric sulfate
At present, the current requirements of gb-4591, polymerized iron sulfate, ferric sulfate storage and transportation standards are implemented.
This standard is applicable to water treatment agent PFS. The product is mainly used for the treatment of drinking water, industrial water, sewage and sludge. It can be used for drinking water treatment.
In addition, Cr (m), Hg, CD and other indicators are added, as well as some technical requirements for production and application of PFS, technical classification and application, and detection methods of PFS. The application of PFS in water treatment is also specified in the national standard. And the product is mainly used for drinking water, industrial water and sewage treatment.
What are the main indicators of Polyferric?
Polyferric sulfate is also the abbreviation of polyferric sulfate. The index of polyferric sulfate is an important basis to measure the quality of products. When you buy Polyferric iron, you can also decide whether to buy it. The following are the main indicators of polyferric sulfate:
1. Total iron content of PFS
The total iron content of PFS is more than 21% in solid and 15% in liquid. These are the product indicators of positive source polyferric sulfate.
2. Polyferric basicity
The basicity of Polyferric is in the range of 9% - 14%, and the good products are generally controlled at about 14%.
3. Density of polyferric sulfate
The density of liquid Polyferric is between 1.3 and 1.5. The higher the density, the thicker the liquid and the better the quality. The liquid Polyferric density of Zhengyuan factory is controlled at 1.45
The above is the national standard of polyferric sulfate, and the main index analysis of polyferric sulfate, hope to help you!
