30/6/2013, · 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.
