Tendenser och trender i tidskriften Vattens artiklar under 75 år /Tendencies and trends in articles published in Vatten – Journal of Water Management and Research during 75 years
The Journal of Water Management and Research (Vatten) celebrates 2019 its 75th anniversary with a special issue, republishing one article per decade from 1940 to 2010. In the present article, we summarize the development of Swedish water research and management based upon the material published in the journal. We read all issues of the journal, […]
Pluviala översvämningar i stort och smått / Pluvial flooding in large and small scale
Urban, pluvial flooding severely effects infrastructure, buildings and urban life during and after extreme rainfall. In this study, spatial analyses of flood claims from insurance companies and the water utility company of Malmö, VA Syd, are used to better understand the mechanisms and characteristics of pluvial flooding. The same data sets are used to analyse […]
Smittspridning från avloppsreningsverk – QMRA som beslutsstöd vid ombyggnation av Arvidstorps reningsverk / Pathogen dispersion from wastewater treatment plants – QMRA as decision support in the renovation of Arvidstorp treatment plant
Source water contamination is a main cause of waterborne disease outbreaks in Sweden and municipal sewage discharges often end up in water sources. At Arvidstorp wastewater treatment plant in Trollhättan, a disc filter has been installed with the primary aim of improving phosphorus reduction. To give permission, the County Administrative Board of Västra Götaland called […]
Årstidsvariationer i sjöar vid klimatförändringar / Seasonal variations in lakes in northern Sweden in a changing climate
Lakes are suitable sentinels of climate change because they constitute a well defined ecosystem and they respond quickly to changes in climate. Many lakes in the northern hemisphere are covered by ice during winter and they are dimictic, which means that the water circulate two times each year. The ice not only prevents gas exchanges […]
Sediment transport and bathymetric change at Honrafjörður tidal inlet / Sedimenttransport och batymetrisk förändring vid Hornafjörðurs tidvatteninlopp
The relatively calm area behind barrier island are favored locations for harbors even though the navigation through the inlet itself can be challenging. Different measures like dredging or coastal structures might be necessary to ensure the desired water depth to maintain a safe navigation. Iceland as an island country depends strongly on reliable navigational routes […]
Industrial ecology tools as decision – making aids for sustainable phosphorus recovery – a methodology paper / Industriell-ekologiverktyg som beslutsstöd för hållbar fosforåtervinning – en metodartikel
India, being the second largest importer, and the largest consumer of phosphate fertilisers in the world, needs to focus on securing its supplies not merely by providing subsidies to importers but also focusing on recovery and recycling of phosphorus from waste streams. In the process, the country can avail of concomitant benefits like wastewater reclamation […]
Microsieving coupled with O3 or ClO2 for treatment and disinfection of combined sewer overflows / Mikrofiltrering i kombination med O3 eller ClO2 för behandling och desinfektion av bräddvatten
A compact combined sewer overflow (CSO) treatment unit is set up and evaluated in pilot-scale. The pilotplant consisted of flocculation, coagulation and a microsieving system followed by a disinfection unit with either O3 or ClO2. Efficiency of the pilot-plant was evaluated with respect to reduction of Escherichia coli, coliform bacteria and intestinal enterococci as well […]
