        What is the difference between the polyaluminium chloride you bought?
        Date of publication:2019-08-01 15:54:04
        As a high molecular polymer, polyaluminum chloride is classified into drinking water grade and industrial grade by content and impurities. It is used in smaller amounts than other coagulants and works better.
         
        Now that China's polyaluminum chloride market is large and the price difference is also large, then Hengyang Jianheng tells you how to measure the quality of the water treatment agent polyaluminium chloride?
         
        The three indicators of aluminum content, salt base and pH are usually used as the measure.
         
        Aluminum content: The national standard content of solid products is generally 28%, which is usually 26%-30% on the market. The liquid product content is 4%-10%.
         
        This indicator is the most direct measure of its effect. Generally speaking, the higher the relative density of the solution, the higher the alumina content. The higher the content, the less the dosage in the water treatment, and the stronger the effect.
         
        Base degree: 40%-90%
         
        The degree of alkalinity is also called the degree of alkalization. It is mainly to measure the ratio of OH content and Al content in the product. The higher the salt base degree, the weaker the stability. The optimum salt base degree is 40%-85%, and in general, the higher the raw water concentration, the higher the salt base degree, and the better the flocculation effect.
         
        pH: 3.5-5
         
        The pH is used directly to indicate the amount of free hydroxide in the solution, usually as the degree of salt changes.
