Roller type polyaluminum chloride is widely used in water treatment processes due to its high efficiency in coagulation and flocculation. It is particularly effective in treating industrial wastewater, municipal water, and drinking water by removing suspended particles, organic matter, and other impurities. Its application ensures clearer water and improves the overall quality of treated water. Additionally, it is utilized in the paper and pulp industry to enhance paper quality and in the textile industry for dye fixation and wastewater treatment. Its ability to work effectively across a wide pH range makes it a versatile choice for various industrial applications.
