Polyaluminum Chloride (PAC) is classified as a chemical product; however, for import and export purposes, it is processed under the procedures for general cargo and is not categorized as a hazardous material.
Nevertheless, because the raw materials used in the production of Polyaluminum Chloride include hydrochloric acid (an acidic corrosive substance), it is essential to adhere to proper handling and usage protocols during operation. By wearing protective gear-such as gloves and face masks-users can effectively prevent the product from causing harm to the human body.
Polyaluminum Chloride is a novel, highly efficient coagulant for water treatment. It demonstrates a marked ability to clarify raw water and also possesses bactericidal, deodorizing, and decolorizing properties. Furthermore, municipal water treatment plants-which supply our daily tap water-utilize "drinking-water grade" Polyaluminum Chloride during the purification process; consequently, Polyaluminum Chloride poses no safety risks when used for water purification purposes.
Polyaluminum Chloride offers numerous advantages, including excellent stability when produced via spray drying, broad applicability across various water sources, rapid hydrolysis rates, strong adsorption capabilities, the formation of large and dense flocs that settle quickly, low residual turbidity in treated water, and superior dewatering performance. The use of spray-dried products ensures safety, minimizes the risk of water-related incidents, and provides a highly secure and reliable solution for residential drinking water supplies. For these reasons, Polyaluminum Chloride is frequently referred to by various abbreviations, such as "High-Efficiency Polyaluminum Chloride," "High-Efficiency PAC," or "High-Efficiency Spray-Dried Polyaluminum Chloride." While Polyaluminum Chloride is suitable for raw water sources of varying turbidity levels and is effective across a wide pH range, its sedimentation performance is significantly inferior to that of Polyacrylamide.
