of acidic wastewater altered its pH to 8.0. The acidic wastewater was elevated to this pH to simulate the alka-line treatment process of the lead acid battery industry. To estimate the sludge generated by this lime addition process, a separate experiment was performed; 15.5 g of hydrated lime was added to one liter of acidic wastewater (pH = 0.96).
