Polyaluminum chloride is a commonly used water treatment agent and is widely used in the water treatment industry. The state has standardized the quality and performance of polyaluminum chloride of water treatment agent, and formulated corresponding national standards.
The national standard for polyaluminum chloride for water treatment agent refers to the standard of polyaluminum chloride for water treatment agent (GB15892-2009), which was jointly issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of the People's Republic of China and implemented in 2009.
The national standard stipulates the indicators of polyaluminum chloride of water treatment agent, mainly including the following:
1.Appearance and color: The national standard stipulates that the appearance of polyaluminum chloride should be yellow to light yellow lump or powdery object.
2.Basic performance indicators of aqueous solution: The national standard stipulates the basic performance indicators of aqueous polyaluminum chloride solution, such as aluminum content, alkalinity, soluble iron content, etc.
3.Adaptability test: The national standard requires adaptability tests under specific conditions to test the adaptability of polyaluminum chloride to different water quality samples.
4.Packaging and marking: The national standard stipulates the packaging requirements for polyaluminum chloride, such as polyethylene plastic bag packaging, and stipulates the signs on the packaging, such as indicating the product name, manufacturer, etc.
According to the provisions of the national standard, the following recommendations should be followed when using the water treatment agent polyaluminum chloride:
1.Adjust the dosage according to the water quality characteristics: according to the actual water quality situation and treatment objectives, reasonably adjust the dosage of polyaluminum chloride to achieve the ideal treatment effect. It can be done according to the detailed instruction manual or by consulting a professional.
2.Use with other treatment agents: The water treatment agent polyaluminum chloride can be used in combination with other water treatment agents, such as aluminum sulfate, polyaluminum silicate, etc., to enhance the treatment effect.
3.Pay attention to the dosing method of the agent: the polyaluminum chloride is evenly added to the water body, and the stirring and mixing are strengthened to ensure that the agent is fully dissolved and dispersed.
4.Regular testing of water quality: After using the water treatment agent polyaluminum chloride, the water quality is monitored regularly to ensure the treatment effect and the adjustment of the dosage.
The state has formulated relevant national standards for water treatment agent polyaluminum chloride to standardize its quality and performance. When using, it should be operated according to the requirements of the national standard, reasonably adjust the dosage, and pay attention to the use of other treatment agents. Monitor water quality regularly to ensure effective treatment. By following the requirements of the national standard, the water treatment agent polyaluminum chloride can be applied more effectively in the water treatment industry and improve the water quality level.
