Neutralization of the ,Acid Wastewater,. For neutralization of the acidic ,wastewater, solution for yeast cultivation, the solution was slowly titrated with solid calcium carbonate (CaCO 3) or calcium hydroxide (Ca(OH) 2) to a pH of 5.5–6.0. The temperature of the titrated solution was maintained at around 25–35°C in an ice-water bath.
