Good stability and low cost! It leaves no issues such as coloring in water supply and industrial wastewater!
Aluminum sulfate is effective against most suspended and floating substances. The surfaces of fine particles present in water as turbidity carry a negative charge, repelling each other and maintaining a stable state. When this product is added, it reacts with the alkalinity in the water to produce positively charged aluminum hydroxide, which neutralizes the negative charges on the surfaces of the fine particles in the turbidity, causing aggregation and forming flocs. These flocs also adsorb fine turbidity particles, becoming larger and heavier, leading to sedimentation. This property is why it is used as a coagulant in drinking water, industrial water, and industrial wastewater. However, if the addition rate of aluminum sulfate is not appropriate, electrical neutralization will be incomplete, resulting in poor aggregation and ineffective treatment. 【Features】 ■ Cost-effective ■ Effective against most suspended and floating substances ■ Good stability ■ Low irritability, making it easy to handle ■ Does not leave problems such as discoloration in drinking water or industrial wastewater *For more details, please refer to the PDF document or feel free to contact us.

Company information
Asada Chemical Industry Co., Ltd. has been a pioneer in aluminum-based coagulants since its founding, producing coagulants such as aluminum sulfate and polyaluminum chloride for water treatment. In addition, we have focused on the production of unsaturated acid metal salt monomers such as zinc methacrylate (R-20S) and acrylic acid salts, which are widely used not only domestically but also internationally as modifiers for rubber and resins in products like golf balls and industrial belts. In recent years, our products have been utilized in a wide range of fields including pharmaceuticals, cosmetics, electronic materials, and automotive materials, and we will continue to challenge the infinite possibilities brought by aluminum and other metal compounds in the future.
