Although their names sound similar, they differ significantly in composition, performance, cost, and applications<\/strong>. At WaterCareChem<\/strong>, we are often asked: \u201cShould I use PAC or PAFC for my project?\u201d<\/em> This guide compares the two, so you can select the most suitable option.<\/p>\n Main Composition:<\/strong> Pure aluminum salt, with no iron content.<\/p>\n<\/li>\n Appearance:<\/strong> Yellow, off-white, or white powder\/granules. (White PAC is food-grade and offers the highest purity.)<\/em><\/p>\n<\/li>\n<\/ul>\n Raw Materials:<\/strong><\/p>\n Drinking water grade: aluminum hydroxide powder.<\/p>\n<\/li>\n Industrial grade: calcium aluminate powder.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n Process:<\/strong> PAC is made by polymerizing aluminum salts, forming strong chains without extra metals.<\/p>\n<\/li>\n<\/ul>\n High Coagulation Capacity:<\/strong> Al\u00b3\u207a ions effectively remove turbidity and color.<\/p>\n<\/li>\n pH Range:<\/strong> Works best between 6\u20139.<\/p>\n<\/li>\n Low Corrosiveness:<\/strong> Safe to use, but efficiency may decrease in colder water.<\/p>\n<\/li>\n Effluent Advantage:<\/strong> Produces soft water, ideal for textile and food-related applications.<\/p>\n<\/li>\n<\/ul>\n Drinking water treatment.<\/p>\n<\/li>\n Industrial water and municipal wastewater.<\/p>\n<\/li>\n Low-turbidity sources like river or lake water.<\/p>\n<\/li>\n<\/ul>\n Main Composition:<\/strong> Combination of aluminum and iron salts (\u22484% iron).<\/p>\n<\/li>\n Appearance:<\/strong> Reddish brown or brown powder.<\/p>\n<\/li>\n<\/ul>\n Raw Materials:<\/strong> Aluminum-calcium powder plus iron compounds (e.g., ferric chloride).<\/p>\n<\/li>\n Process:<\/strong> Adds an iron-ion introduction step to enhance floc formation and sedimentation.<\/p>\n<\/li>\n<\/ul>\n Synergistic Performance:<\/strong> Aluminum\u2019s adsorption-bridging power combines with iron\u2019s rapid precipitation ability.<\/p>\n<\/li>\n Stable at Low Temperatures:<\/strong> Works well in cold or fluctuating water conditions.<\/p>\n<\/li>\n Enhanced Pollutant Removal:<\/strong> Superior at removing heavy metals (Cr\u2076\u207a), COD, and phosphorus<\/strong>.<\/p>\n<\/li>\n Dense Flocs:<\/strong> Easier sludge dewatering after treatment.<\/p>\n<\/li>\n<\/ul>\n Industrial wastewater only (not for drinking water).<\/p>\n<\/li>\n High-pollution sources such as steel, paper, and textile wastewater.<\/p>\n<\/li>\n Water requiring heavy metal and phosphorus removal.<\/p>\n<\/li>\n<\/ul>\n PAC:<\/strong><\/p>\n Cost: Higher, especially white food-grade.<\/p>\n<\/li>\n Dosage: 1\u201315 g per ton of water.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n PAFC:<\/strong><\/p>\n Cost: Lower raw material base, cost-effective for large volumes.<\/p>\n<\/li>\n Dosage: 3\u201340 g per ton of water, depending on pollution level.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n Choose PAC if:<\/strong><\/p>\n You need safe drinking water treatment.<\/p>\n<\/li>\n Effluent softness matters (e.g., textiles, food processing).<\/p>\n<\/li>\n Source water has low turbidity and stable temperature.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n Choose PAFC if:<\/strong><\/p>\n You are treating highly polluted industrial wastewater.<\/p>\n<\/li>\n Heavy metal or phosphorus removal is required.<\/p>\n<\/li>\n Water conditions are cold, fluctuating, or highly variable.<\/p>\n<\/li>\n Cost-effectiveness is a priority for large-scale operations.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n Both PAC and PAFC<\/strong> are powerful coagulants, but they serve different needs:<\/p>\n PAC<\/strong> is best for drinking water and low-pollution sources<\/strong>, where safety and effluent softness are key.<\/p>\n<\/li>\n PAFC<\/strong> is ideal for industrial wastewater<\/strong>, offering stronger performance, adaptability, and lower cost.<\/p>\n<\/li>\n<\/ul>\n At WaterCareChem<\/strong>, we provide:<\/p>\n PAC and PAFC samples for testing.<\/p>\n<\/li>\n Small-scale test guidance and technical support.<\/p>\n<\/li>\n Bulk supply tailored to your water treatment needs.<\/p>\n<\/li>\n<\/ul>\n ????
