In the competitive landscape of industrial chemical supply, the cost-effectiveness of a product is a significant factor influencing its adoption. Aluminum sulfate consistently emerges as a favored choice due to its relatively low production cost and its ability to deliver high performance across a range of applications, particularly in water treatment and papermaking. Compared to alternative coagulants and sizing agents, aluminum sulfate often presents a more economical option without compromising on efficacy.

From an environmental perspective, aluminum sulfate's role in water purification contributes positively to environmental sustainability by ensuring cleaner water discharge and enabling water reuse. In papermaking, its use in conjunction with other agents can lead to more efficient processes, potentially reducing waste. While the chemical itself requires responsible handling and disposal, its primary applications are geared towards environmental improvement. For instance, its use in treating papermaking white water, as highlighted in research, aims to reduce chemical oxygen demand (CODcr) and facilitate the recycling of water within the mill, thereby minimizing the environmental footprint of paper production. This focus on closed-loop systems and water reuse demonstrates how aluminum sulfate can be an integral part of more sustainable industrial practices. The chemical industry is continually exploring ways to enhance the environmental profile of its products, and aluminum sulfate's established benefits in pollution control and resource management make it a valuable component in this pursuit.
