Polyaluminum chloride (PAC) is a commonly used water treatment agent. In order to ensure the quality and use of polyaluminium chloride, China has formulated a set of national standards to regulate the production and application of polyaluminium chloride.
The number of the national standard is GB T 15892-2019 "Polyaluminum Chloride", which is a standard issued by the State Administration for Market Regulation.
The national standard for polyaluminum chloride mainly includes the following:
1.Terms and definitions: The standard provides clear definitions of terms related to polyaluminium chloride to ensure a uniform understanding.
2.Specification requirements: The standard stipulates the requirements for important indicators such as the appearance, effective aluminum content, and secondary agglomeration time of polyaluminum chloride to ensure the quality of the product.
3.Inspection methods: The standard lists the inspection methods of various indicators of polyaluminum chloride, including appearance inspection, aluminum content determination, pH value determination, agglomeration time determination, etc., for the reference of production enterprises and testing institutions.
4.Marking, packaging, transportation and storage: The standard specifies the marking, packaging, transportation and storage requirements for polyaluminium chloride products to ensure the safety and shelf life of the product throughout the ** chain.
1.Water treatment: Polyaluminum chloride can be used in sewage treatment, drinking water treatment and industrial water treatment. It can effectively remove turbidity, color, grease and organic matter from water.
2.Pulp and paper industry: Polyaluminium chloride can be used in processes such as deinking, enrichment and coloring in pulp and paper processes.
3.Textile and dye industry: Polyaluminum chloride can be used for water treatment in textile and dye processes, removing impurities and pigments in water, etc.
4.Mining and metallurgical industry: Polyaluminum chloride can be used for wastewater treatment in mining and metallurgical processes to remove suspended solids and heavy metal ions in wastewater.
The formulation and implementation of national standards for polyaluminum chloride are of great significance to the following aspects:
1.Product quality assurance: The standard stipulates the specification requirements and inspection methods of polyaluminum chloride products, ensures the quality and effectiveness of the products, and improves the trust of users in the products.
2.Enterprises standardize production: The standard establishes the requirements for the labeling, packaging, transportation and storage of polyaluminum chloride, and standardizes the production and operation behavior of enterprises.
3.Improvement of water treatment effect: The standard formulates the use of polyaluminum chloride in various application fields to help users correctly select and use polyaluminum chloride and improve the effect of water treatment.
4.Promote the development of the industry: The formulation of standards provides unified technical specifications and reference standards for the development of the polyaluminum chloride industry, and promotes the healthy development of the industry.
The national standard for polyaluminum chloride regulates and guides the quality and use of polyaluminum chloride products to ensure the quality and effectiveness of the products. The formulation and implementation of standards are of great significance to ensure the effect of water treatment and promote the development of the industry. By accurately understanding and correctly using the national standard for polyaluminium chloride, polyaluminium chloride can be better applied, providing better results and quality assurance for applications in water treatment and other fields.
