Wastewater with a low pH is generally neutralized using sodium hydroxide (NaOH), lime (CaO), magnesium hydroxide (Mg(OH) 2), or calcium hydroxide (Ca(OH) 2). Wastewater with a high pH is generally neutralized with sulfuric acid (H 2 SO 4), hydrochloric acid (HC 1), or carbon dioxide (CO 2). The most common chemicals used are H 2 SO 4 and NaOH. Neutralization can be accomplished by batch …
