Berörda intressenters deltagande i vattenförvaltning – förändring, förnyelse och arv / Stakeholder participation in water management – change, renewal and legacy
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 […]
Management of hydrogen sulfide in anaerobic digestion of enzyme pretreated marine macro-algae / Vätesulfidhantering vid rötning av enzymförbehandlade marina makroalger
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 impact of waves on the distribution of submerged macrophytes in kalvöfjord, sweden – a study of “comfort zones” / Vindvågors betydelse för distributionen av makrofyter i kalvöfjorden, – en studie av »komfortzoner»
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 […]
Microbiological runoff water quality from a green roof and in an open stormwater system / Mikrobiologiska föroreningar i avrinningsvatten från ett grönt tak och i ett öppet dagvattensystem
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: […]
Översvämningsförordningens betydelse för fysisk planering / The impact of the EU Flood Directive on physical planning in Sweden
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 […]
Urban Flooding – Planning for a blue and green city – en internationell konferens i Malmö 14–15 mars 2012
I våras arrangerade Föreningen vatten och Peter Stahres Stipendium en internationell konferens för att inspirera till kreativa lösningar för blå och gröna dagvattenlösningar som en viktig del i det hållbara stadsbyggandet och för att inspirera till flera stipendieansökningar. I detta nummer av Vatten presenteras korta sammanfattningar av föredragen tillsammans med en sammanfattning av de workshops […]
Anammox i huvudströmmen – vad är problemet? / Anammox in the mainstream – what is the problem?
When Swedish wastewater treatment plants were rebuilt to include enhanced nitrogen removal, anaerobic ammonium oxidation (anammox) was far from being a mature technology. During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is decreasing, but lab- and pilot-scale studies on real municipal wastewater […]
Kontinuerlig föroreningsspridning från vägbroar till ytvattenrecipienter med tillämpning på Segeåns avrinningsområde / Continous pollutant emissions from road bridges to receiving waters with application to the Segeån catchment area
Heavily trafficked roads routinely generate a wide spectrum of pollutants, many of these are listed as priority substances according to the EU Water Framework Directive (WFD). Watercourses that intersect with major roads are exposed to both airborne and waterborne traffic generated pollutants, possibly deteriorating the receiving waters. Four bridges within the Segeån catchment area (in […]
