Wastewater produced during turpentine manufacturing contains a substantial amount of persistent organic substances derived from turpentine oil and its associated compounds. These pollutants, commonly represented by biochemical oxygen demand (BOD), chemical oxygen demand (COD), oil and grease (O&G), and total suspended solids (TSS), present significant challenges for conventional wastewater treatment technologies. Single-stage biological or chemical treatment processes are generally insufficient due to the presence of high-molecular-weight and poorly biodegradable organics. This study examines the performance of an integrated treatment system combining anaerobic–aerobic biofiltration with Fenton oxidation, referred to as the BIOTON process, for the treatment of turpentine wastewater. System performance was evaluated through continuous monitoring of COD, BOD, O&G, and TSS using an Internet of Things (IoT)-based data acquisition system. The experimental results demonstrated that the combined biological and chemical oxidation processes significantly enhanced pollutant removal efficiency. Under optimal operating conditions, removal efficiencies of 99.6% for COD, 99.0% for BOD, 99.8% for O&G, and 98.8% for TSS were achieved after 80 h of treatment. The implementation of IoT technology enabled real-time monitoring and improved data accuracy, confirming the BIOTON system as a reliable and effective solution for high-strength turpentine wastewater treatment. © 2026 Indian Chemical Society.
