The waste from phosphoric acid plants usually consist of gypsum pile drainage. It is highly acidic with a pH of 1.0 to 1.8. Two-Stage Neutralization. The extremely acidic drainage requires a two stage neutralization system. Clarification occurs between stages. The first stage uses lime to capture fluoride and elevate the pH to 4.5.
