Governments have imposed regulations on the procedures required to dispose ,of industrial, waste. An acid neutralization system treats and measures ,the acidity, of ,wastewater, as it exits the production line. Depending on the process, a suitable ,neutralizing, chemical is added to reduce ,the acidity,.

Acid drainage (AD) poses a significant concern for water pollution due to its strong ,acidity, and the toxicity of its various contaminants (e.g., heavy metal ions). In order to minimize the harmful effects of AD, ,the acidity, must be neutralized and the contaminants be removed. The capacity of calcined Mg/Al layered double hydroxide (Mg/Al-CLDH) for simultaneously ,neutralizing, the pH of AD and...
