Enhancement of anaerobic digestion of sludge from Kraft pulp mill wastewater treatment using thermal hydrolysis
Resumen:
In the present work, the biodegradation improvement after thermal hydrolysis of the sludge generated in the aerobic wastewater treatment of a cellulose industry was evaluated. Response surfaces are presented for the different variables tested -Biomethane Potential (BMP), methane production rate and Dissolved Organic Nitrogen (DON). The variation of kinetic parameters was also determined. Increases between 100 % and 228 % were obtained for the BMPs of thermally hydrolyzed biosludge compared to untreated biosludge. In addition, increases of up to 112 % for the methane production rate of thermally hydrolyzed substrate were obtained.
