Project: Adsorptive removal of COD from coolant oil wastewater using pyrochar from rain tree branches
- Raintree branches were converted into pyrochar via oxygen-free pyrolysis for use as an adsorbent in wastewater treatment, aiming to reduce organic waste and support renewable resource utilization.
- The pyrochar removed 91.53% of COD within 240 minutes. Adsorption data fit the pseudo-second-order kinetic model and Langmuir isotherm, with a maximum adsorption capacity of 417 mg/g.
- Post-adsorption pyrochar exhibited an increased calorific value (6,278.8 cal/g), highlighting its potential as an alternative fuel and a sustainable solution for industrial wastewater management.
