1. Water Treatment: Efficient Purification for Safer Water
Aluminum sulfate serves as a high-efficiency coagulant in water treatment, widely used in drinking water purification and industrial wastewater treatment. Its mechanism involves the release of trivalent aluminum ions (Al³⁺) upon dissolution, which rapidly neutralize negatively charged suspended particles, colloids, and microorganisms through charge neutralization. This process forms large flocs that precipitate, significantly improving water clarity and reducing turbidity. Additionally, aluminum sulfate effectively removes organic matter, pigments, and reduces chemical oxygen demand (COD) and biochemical oxygen demand (BOD), offering an economical and eco-friendly solution for wastewater treatment plants.
Jiangsu LanYao’s aluminum sulfate products strictly adhere to industry standards, with arsenic content below 5 mg/kg, ensuring safety in drinking water treatment. Cost-effective and reliable, they are the preferred choice for municipal water supply and industrial water treatment.
2. Papermaking Industry: Enhanced Performance and Streamlined Processes
In papermaking, aluminum sulfate is applied across pulp preparation, sizing, and wet-end chemistry, delivering core advantages:
- Improved Sizing Efficiency: As a sizing agent, aluminum sulfate interacts with rosin soap to align hydrophobic groups on fiber surfaces via positively charged adsorption, boosting paper’s water resistance and anti-penetration properties for high-end printing and packaging applications.
- Strength and Brightness Enhancement: By strengthening fiber bonding, it enhances wet strength, burst resistance, and smoothness while removing impurities to optimize paper brightness.
- Process Optimization: It adjusts pulp pH, improves drainage speed, reduces web breaks, and lowers pollutant emissions, supporting green production practices.
To address industry challenges, Jiangsu LanYao offers low-corrosivity aluminum sulfate products paired with customized dosing solutions, mitigating pipeline corrosion and fabric clogging to extend equipment lifespan.
3. Diverse Applications Across Industries
Aluminum sulfate excels in multiple sectors:
- Firefighting: A key component in foam fire extinguishing agents, reacting with sodium bicarbonate and foaming agents to suppress flames rapidly.
- Cosmetics and Daily Chemicals: Acts as an astringent in antiperspirants, stabilizing product formulations by regulating skin surface pH.
- Industrial Manufacturing: Functions as a precipitating and color-fixing agent in dye production (e.g., chrome yellow pigments), wood preservation, and oil decolorization.
