Sodium Aluminate Liquid - Naalo2, Density: 1.35 G/cmâ³, Colorless | Ph Adjustment, Coagulation, Water Treatment, Removes Impurities, Easy To Use

Sodium aluminate is commonly used as a basic coagulant for treating acidic effluent in water treatment processes. Here are some key points to consider:

pH adjustment: Sodium aluminate is a basic coagulant, which means it raises the pH of the acidic effluent to a level where coagulation can occur. Typically, the pH range for effective coagulation with sodium aluminate is between 7.5 and 9.0.

Coagulation mechanism: Sodium aluminate works by destabilizing the negatively charged colloidal particles in the effluent, causing them to clump together and settle out of the water. This process is called coagulation.

Dosage: The optimal dosage of sodium aluminate will depend on the specific characteristics of the effluent, including its pH, turbidity, and chemical composition. Typically, dosages range from 10 to 200 mg/L.

Safety considerations: Sodium aluminate is a caustic substance and can cause severe burns if it comes into contact with skin or eyes. It is important to handle it with care and follow appropriate safety protocols.

Other considerations: In addition to its coagulation properties, sodium aluminate has other uses, such as in the manufacture of paper, ceramics, and detergents. It is also used as a source of aluminum ions in water treatment processes, which can help to remove dissolved organic matter and phosphorus.
