contain many different elements such as chromium, titanium, ,nickel,, zirconium and molybdenum [3]. The combined ,wastewater, from all pickling processes will therefore contain a wide range of elements, in this study the focus is phosphorus (P). In order to release the ,wastewater, into the environment, its ,acidic, content needs to be neutralized.

Acid mine drainage - Wikipedia
Acid mine drainage - Wikipedia

Acid mine drainage,, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of ,acidic, water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...

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.
