In rubber skim block production, use of sulfuric acid is a general practice, which generates acidic wastewater (pH 2.4±0.5) with high chemical oxygen demand (COD) (14,911±1,819mg/L) and sulfate (6,506±1,038mg/L). Our work aimed to pretreat this wastewater separately prior to combining with the other...
