For wastes entering biological treatment processes, the pH should be maintained between 6.5 and 9 for optimum growth of the microorganisms. Acidic wastes are commonly neutralized with waste alkaline streams, lime, dolomite, ammonia, caustic soda, or soda ash. Lime is the most widely used alkaline material for neutralization acid wastes because of its low cost.

An alternative method to the lime-soda ash softening process is the use of sodium hydroxide (NaOH), which is called caustic soda. The chemical reactions using caustic soda demonstrate that in removing carbon dioxide and carbonate hardness, sodium carbonate (soda ash) is formed, which will react with to remove non-carbonate hardness. Sodium hydroxide substitutes for soda ash and part of the lime to …
