1. Wastewater discharges and microbial variability in a surface water source
Abstract : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. READ MORE

2. Simulation and Optimization of Recirculating Aquaculture Systems
Abstract : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.

4. 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. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability
Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.
