Precipitation of metals in the metals removal treatment processes. 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 (HCl), or carbon dioxide (CO 2).
