Polyaluminium Chloride (PAC) vs. Aluminum Sulfate: A Treatment Advantage
In the realm of water treatment, coagulants play a vital role in purifying water by clumping together impurities for easier removal. For decades, aluminum sulfate (alum) has been a staple in this process. However, advancements in chemical technology have led to the development of superior alternatives, with Polyaluminium Chloride (PAC) standing out as a highly effective and increasingly preferred option. As a leading supplier of water treatment chemicals, we frequently address questions about the benefits of choosing PAC over traditional coagulants. Let's delve into why PAC offers a significant advantage.
One of the primary drawbacks of using aluminum sulfate is its tendency to leave behind substantial traces of aluminum in the treated water. This necessitates additional filtration steps and contributes to the generation of large volumes of sludge. Managing and disposing of this sludge incurs significant operational costs for water treatment plants, impacting overall efficiency and profitability. Furthermore, residual aluminum in water supplies can raise concerns regarding water quality and environmental impact.
Polyaluminium Chloride, on the other hand, has been engineered to overcome these limitations. PAC hydrolyzes more readily and forms flocs faster, making it a much more efficient coagulant. Crucially, PAC products typically contain lower concentrations of aluminum, resulting in significantly reduced aluminum residuals in the final water output. This translates directly to less sludge waste, lowering disposal costs and simplifying the treatment process. For industries such as paper manufacturing, municipal water purification, and treating print & dye wastewater, these advantages are invaluable.
The performance of PAC is also superior in several other aspects. It exhibits better coagulation properties and can achieve effective clarification even at lower temperatures, a common challenge for aluminum sulfate. The wide applicable range of PAC for pH values also means it can be used in a broader array of water conditions without requiring extensive pH adjustment chemicals. This makes it a more versatile and forgiving chemical to work with. When you decide to buy PAC, you are opting for a more advanced, environmentally conscious, and economically viable solution.
