Electrocoagulation treatment of wastewater collected from Haldia industrial region: Performance evaluation and comparison of process optimization.

This study investigates the treatment of oil-contaminated wastewater with high levels of inorganic substances, suspended solids and turbidity, collected from the Haldia industrial region of India in February 2023. The wastewater, originating from industries such as chemical, petrochemical, textile, and battery manufacturing, presents a complex pollutant load that challenges traditional treatment methods. Electrocoagulation was employed as the treatment technique, with process optimization conducted using Box-Behnken design (BBD) and central composite design (CCD) for key parameters: pH, initial oil concentration, current density, and electrolysis time.

Assessment of Solubility Behavior of a Copolymer in Supercritical CO and Organic Solvents: Neural Network Prediction and Statistical Analysis.
