Sodium Aluminate (NaAlO₂) is an inorganic chemical compound used primarily as a coagulant and pH adjuster in water and wastewater treatment. It is a strong alkaline substance that reacts with water to form aluminum hydroxide (Al(OH)₃), which acts as a flocculant to remove suspended solids, color, and impurities from water. Sodium Aluminate is commonly used as a substitute or complement to alum or PAC in water treatment due to its high efficiency and fast action.
