According to different uses, polyaluminum chloride is divided into polyaluminum chloride for water treatment agent and polyaluminum chloride for drinking water. Due to the difference in raw materials, it has been developed into two standards.
At present, there are mainly GB/T 22627-2014, GB/T 22627-2022, GB15892-2009, GB15892-2022 standard products on the market. Now compare the main parameters in the standard.
- Polyaluminum chloride for water treatment agent standard GB/T 22627-2014 vs GB/T 22627 -2022
Note: The mass fractions of Insoluble substance, Fe,N,As, Pb, Cd, Hg, and Cr are calculated based on that of Al2O3 as 10.0%. When the concentration of Al2O3 is over 10.0% the standard need to be calculated as a multiple of 10.0%.
- Polyaluminum chloride for drinking water standard GB15892-2009 vs GB15892-2020
Note: The mass fractions of Insoluble substance, Fe,As, Pb, Cd, Hg ,Cr, and Cr6+ are calculated based on that of Al2O3 as 10.0%. When the concentration of Al2O3 is over 10.0% the standard need to be calculated as a multiple of 10.0%.
