The Role of Polyaluminum Chloride in Transforming Traditional Water Treatment Processes
Polyaluminum chloride (PAC) has emerged as a groundbreaking solution over the past four decades, evolving into an industrialized, high-efficiency, and energy-saving separation process. Currently, established agents like ferric sulfate, aluminum sulfate, calcium hydroxide, and polyacrylamide are widely applied across industries such as oil, chemicals, insurance, energy, and electronics, delivering significant economic and social benefits. These technologies are poised to play a pivotal strategic role in industrial transformations throughout the 21st century. Below are some key applications of water treatment agents.

In the pharmaceutical sector, polyaluminum chloride is primarily utilized for filtration and sterilization, while microfiltration represents its second-largest market for producing high-purity water. There's also untapped potential in the drinking water production and urban sewage treatment sectors, where PAC offers cost-effective solutions for removing municipal sewage viruses compared to ultrafiltration. Ferric sulfate heptahydrate and PAC are extensively used in industrial wastewater treatment, such as separating solvents from pigments, eliminating refractory particles from oily wastewater, and removing hazardous heavy metals like cadmium and mercury from electroplating effluents. The fuel industry employs PAC to extract wax and asphaltenes from oils. Moreover, with the growth of the biotech sector, the demand for PAC in this field is expected to expand significantly.
Polyaluminum chloride is set to revolutionize conventional distillation techniques. Unlike traditional methods that rely on boiling points, PAC facilitates separation through dissolution and diffusion, making it ideal for handling azeotropes. Its primary uses include dehydrating organic solvents, removing trace amounts of solvents, and purifying organic/organic mixtures. Pervaporation technology, pioneered abroad in the 1980s, has since achieved industrial success. This approach will continue to gain traction, especially in the separation of organic mixtures, serving as both an alternative and complementary method to conventional distillation. PAC holds immense promise within the petrochemical industry.
Polyaluminum chloride boasts extensive applications across industries including petrochemicals, food processing, metallurgy, environmental engineering, and bioengineering. Over the last five years, China has made remarkable strides in developing PAC, progressing from initial production to achieving an initial stage of industrialization. Our current scale and automation capabilities now rival international standards. Looking ahead, China’s PAC will play a crucial role in gas separation and purification, facilitating the integration of ferric sulfate with other processes, and transforming traditional systems. Gradually, we aim to establish a novel, integrated application technology centered around PAC.
As industries continue to evolve, polyaluminum chloride stands at the forefront of innovation, offering sustainable and efficient solutions for tomorrow’s challenges.
