Compared with traditional coagulants such as aluminum sulfate, polyaluminum chloride offers faster reaction speed, stronger floc development, and more stable treatment outcomes. These characteristics make PAC particularly suitable for processes that require high water clarity, efficient solid-liquid separation, and consistent water quality.
Due to its high cationic charge density, polyaluminum chloride can quickly destabilize negatively charged particles and promote effective coagulation. During treatment, PAC forms dense and stable flocs that settle rapidly, improving sedimentation and solid-liquid separation efficiency. In addition, PAC remains effective over a broad pH range, typically between pH 5 and 8, allowing it to adapt to various water qualities without significant pH adjustment. Its efficient reaction behavior also results in lower residual aluminum levels in treated water, helping treatment systems meet strict environmental discharge and drinking water quality standards.
