This paper is about the EU Flood Directive and its implementation in Swedish laws and regulations. The effect of the Directive on flood management in Sweden is analysed with special focus on physical planning. The Swedish Flood Ordinance gives most of the responsibility for flood related actions to national and regional authorities, with the Swedish […]

Microbiological quality of stormwater runoff from a green roof and in an open stormwater system in Augustenborg, Malmö, Sweden was studied. Since the stormwater is managed in an open system there is a possibility of human contact with that water and a potential risk for public health. Four locations have been selected as sampling points: […]

A study of a shallow bay (Kalvöfjord) on the west coast of Sweden was conducted to determine the potential for wind waves to control the distribution of submerged macrophytes. A wave model was implemented, calculating the drag force exerted by the wave orbital motion. A new concept of “comfort zones” was introduced, ascribing an interval […]

Enzymatic pretreatment of algae by means of cellulose degrading enzyme was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. Lab-scale batch anaerobic digestion experiments showed comparatively low methane potential for the pretreated algae at both mesophilic and thermophilic temperatures. However, the raw […]

The EU Water Framework Directive was adopted 2000 and aims at achieving good water quality in inland and coastal water. Two significant changes are that water should be managed according to natural boundaries and the emphasis on involving public and concerned stakeholders. These challenges call for a broadened knowledge on how to incorporate the new […]

A one-dimensional, unsaturated transport model was used to simulate non-reactive transport of solutes. The effects of soil water hysteresis, and temporal variability in precipitation and evapotranspiration input data were evaluated. Simulations were conducted in HYDRUS-1D code for the period 1996–2008 for three different geographic locations in Sweden and for three different soil textures. Simulations were […]

The scope for wastewater treatment plants (WWTPs) widens to consider not only water quality and cost, but also energy efficiency and greenhouse gas (GHG) emissions. The on-going research project, “Development and dynamic analysis of operational strategies for enhanced energy efficiency of wastewater treatment systems” aims to develop a tool for integrated evaluation of energy efficiency […]
