Selecting the appropriate coagulant is a critical decision for any water treatment facility. Historically, aluminum sulfate (alum) has been a widely used option. However, advancements in chemical technology have introduced Polyaluminum Chloride (PAC) as a highly effective and often superior alternative. As a prominent supplier of PAC, we aim to clarify the distinctions between these two coagulants to help you make the most informed choice for your operations.

Aluminum sulfate, a traditional coagulant, works by forming aluminum hydroxide precipitates that entrap impurities. While effective in removing turbidity and color, its use often results in significant drawbacks. A major concern is the substantial amount of aluminum residuals left in treated water, which can have environmental and health implications and necessitate further purification steps. Furthermore, alum usage typically generates large volumes of sludge, increasing disposal costs and creating disposal challenges. The process also requires careful pH adjustment, as alum tends to lower water pH significantly.

Polyaluminum Chloride, on the other hand, offers several key advantages rooted in its advanced polymeric structure. PAC provides more efficient coagulation at lower dosages, meaning less chemical is needed to achieve desired water clarity. It forms larger, denser flocs that settle more rapidly, improving sedimentation efficiency and reducing the burden on downstream filtration systems. Crucially, PAC leaves significantly fewer aluminum residuals in the treated water and produces less sludge compared to aluminum sulfate. This not only enhances environmental sustainability but also reduces operational costs associated with sludge management and chemical consumption. Moreover, PAC has a less pronounced effect on water pH, simplifying treatment processes and minimizing the need for additional pH adjustment chemicals.

When considering the cost-effectiveness and performance, PAC often emerges as the preferred choice for modern water treatment. If you are looking to buy Polyaluminum Chloride, partnering with a reliable manufacturer in China ensures access to high-quality products at competitive prices.
