Sodium carbonate- Soda Ash

How Soda Ash is Used in ETPs:

• pH Adjustment:

  Soda ash is an alkaline substance, making it suitable for raising the pH of acidic wastewater. This is important because many industrial processes generate acidic effluents, and maintaining a suitable pH is crucial for effective treatment.

• Water Softening:

  Soda ash can help soften water by precipitating calcium and magnesium ions, which are responsible for water hardness.

• Coagulation and Flocculation:

  By adjusting the pH, soda ash can improve the performance of coagulants like alum or ferric chloride, which are used to remove suspended solids from wastewater.

• Cost-Effectiveness:

  Soda ash is a relatively inexpensive chemical, making it an attractive option for large-scale water treatment applications like ETPs
