Sodium Aluminate Coagulant
Sodium aluminate (NaAlO2) is an alkaline coagulant that simultaneously provides coagulation and pH correction, making it valuable for treating acidic wastewaters and low-alkalinity source waters. It generates aluminum hydroxide flocs under alkaline conditions and is particularly effective for color and NOM removal in soft waters.
