2. Anaerobic digestion in the kraft pulp and paper industry : Challenges and possibilities for implementation
Abstract : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

5. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools
Abstract : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. READ MORE
