The product indices in Table 1 of this Standard are all compulsory and other content is recommendatory.
This standard is not equivalent to the corresponding Japanese Industrial Standard JIS K1475: 2006 Poly Aluminium Chloride for Water Supply(Japanese version) and American Water Works Association Standard ANSI/AWWA B 408: 2003 Liquid Poly Aluminium Chloride (English Version).
Compared with JIS K 1475: 2006 and ANSI/AWWA B 408: 2003, the main differences are as follows:
- liquid poly aluminium chloride and solid poly aluminium chloride are included in this Standard.
- the technology index of basicity is increased according to the technological advance of poly aluminium chloride, and the production process and material source of poly aluminium chloride industry in China.
- the inspection method related to the heavy metal indices is changed.
- “the determination of ammoniacal nitrogen” is deleted.
This Standard replaces GB 15982-2003 Water Treatment Chemical – Poly Aluminium Chloride. Compared with GB 15890-2003, the main differences are as follows:
- This Standard name was changed into Poly Aluminium Chloride for Treatment of Drinking Water
- The technical index in Table 1 has been changed.
- The inspection method of aluminum oxide with CuSO4 standard volumetric solution is added.
- The determination method of some technical indices is modified.
-"The determination of ammonia nitrogen" is deleted.
Appendix A is informative.
This standard was proposed by China Petroleum and Chemical Industry Association.
This standard is under the jurisdiction of Subcommittee on Water Treatment Agent of the National Technical Committee on Chemical of Standardization Administration of China (SAC/TC 63/SC5).
