While Polyaluminium Chloride (PAC) is widely recognized for its indispensable role in water and wastewater treatment, its utility extends into various other industrial sectors, particularly in chemical processing. The unique properties of PAC, stemming from its pre-hydrolyzed polymeric aluminum structure, make it a versatile agent for a range of applications beyond simple coagulation. As a prominent manufacturer and supplier of specialty chemicals, we are keen to highlight the broader industrial applications where PAC demonstrates significant value.

PAC as a Chemical Processing Aid

The ability of PAC to act as a flocculant, coagulant, and to stabilize dispersions makes it useful in several chemical processing contexts:

  • Paper and Pulp Industry: Beyond its well-known function in treating papermaking wastewater, PAC is also used as a sizing agent and a retention aid in the paper manufacturing process itself. It helps to improve the bonding of fibers and fillers, enhancing paper strength and printability. Its cationic nature aids in retaining fine particles and improving drainage on the paper machine.
  • Textile Industry: In textile dyeing and finishing, PAC can be employed as a fixing agent for dyes, improving color fastness and reducing dye runoff into wastewater. It can also be used in wastewater treatment to remove residual dyes and other processing chemicals.
  • Leather Tanning: The leather industry utilizes various chemicals in its tanning and finishing processes. PAC can act as a tanning agent or a retanning agent, influencing the leather's properties such as softness and fullness. It also aids in the treatment of tannery effluents, which are often high in organic pollutants and heavy metals.
  • Cosmetics and Personal Care: Certain forms of aluminum compounds, including aluminum chlorohydrate (a type of PAC), are used as active ingredients in antiperspirants and deodorants. They work by forming temporary plugs in sweat ducts, reducing sweat flow.
  • Concrete and Construction: In some construction applications, PAC can be used as a concrete accelerator or hardener. It influences the setting time and strength development of concrete, particularly in specialized formulations.
  • Glycerine Refinement: The refinement of crude glycerine often involves removing impurities and color. PAC can be employed in this process to help precipitate unwanted organic matter and improve the purity and color of the final glycerine product.

The Manufacturer's Advantage in Specialty Applications

The effectiveness of PAC in these diverse applications often depends on specific formulations and grades tailored to meet particular performance requirements. As a manufacturer, we have the capability to produce various grades of Polyaluminium Chloride, adjusting parameters such as basicity and Al2O3 content to suit niche industrial needs. This flexibility allows us to serve as a valuable partner for companies seeking specialized chemical solutions.

For businesses involved in chemical processing that require agents for flocculation, dispersion stabilization, or enhancing product properties, exploring the capabilities of Polyaluminium Chloride is highly recommended. By leveraging our expertise as a leading supplier, you can identify the optimal PAC grade for your unique industrial challenges, thereby improving process efficiency and product quality.
