Polyaluminium chloride powder, usually abbreviated as PAC, is a highly efficient and broad-spectrum inorganic high-molecular flocculant. It is a yellow, light yellow or brownish-yellow powder. It is an inorganic high-molecular flocculant that can efficiently remove colloids, suspended solids and some dissolved pollutants from water through the principles of electro-neutralization and adsorption bridging. Due to its advantages such as high efficiency, strong adaptability and relatively low cost, polyaluminum chloride powder has become one of the most widely used and important flocculants in the water treatment industry today.
