A new research project being executed at Karlstad University in Sweden will validate a way that maximises biogas production from forest industrial sewage sludge, while reducing electricity and chemical consumption.
Energy-efficient purification of forest industrial wastewater is a key issue for the pulp and paper industry. To achieve energy efficiency, treatment processes and sludge management need to be handled holistically. Most Swedish mills treat their wastewater by applying energy-intensive aerobic biological methods. Some add a chemical treatment, which is energy-efficient, but adds a cost for precipitation chemicals and produces large quantities of sludge. An alternative is anaerobic digestion, which uses forest industry sludge to produce energy as biogas.
