PAC is primarily used as a coagulant in drinking water treatment, sewage treatment, and industrial wastewater processing. Due to its unique properties, it exhibits superior coagulation performance compared to traditional coagulants like alum. The advantages of using PAC include higher removal rates for suspended solids and organic matter, reduced sludge production, and improved water quality. Its efficiency allows for the use of lower doses, thereby enhancing cost-effectiveness in large-scale operations.

Another significant benefit of PAC is its versatility across various applications. The compound can be used in not just water treatment, but also in the paper, textile, and food industries. Its role in pulp and paper manufacturing aids in improving the strength and brightness of the product, while in the textile industry, it serves as a mordant for dyeing processes. Moreover, in the food industry, PAC is utilized in food processing for clarification and stabilization.

The safety of polyaluminium chloride has been a topic of considerable discussion, particularly since it is utilized in drinking water treatment processes. PAC is generally recognized as safe when used according to established guidelines. Regulatory agencies such as the Environmental Protection Agency (EPA) and the World Health Organization (WHO) have deemed PAC suitable for use in potable water systems, provided that it is handled properly and the residuals are monitored. However, like any industrial chemical, safety measures must be observed during the handling, storage, and application to mitigate any potential risks associated with exposure.
