The purpose of the research was to study the behavior of lignin degradation under different conditions (T 110–190°C, pO₂ 0.5–1.5 MPa, pH 5, 9 and 12) and to develop a predictive model. Temperature increase improved lignin removal from 75% at 110°C to 100% at 190°C (experimental). Increasing the pH enhanced the lignin removal efficiency from 30 to 97% (experimental). The developed model predicted the lignin degradation and changes in COD, BOD and TOC. The model agreed well with the experimental data (R ² = 0.93 at pH 5 and 12).
