CHEMICAL DENITRIFICATION OF LANDFILL LEACHATES UNDER FREEZING/THAWING CONDITIONS / Kemisk denitrifikation av lakvatten från deponier vid frysning/upptining
Chemical denitrification has been proposed (Nikolic and Hultman, 2003) as the second part in a new treatment system for landfill leachates, where ammonium or urea is oxidized with nitrite to yield nitrogen gas and water. Concentrated aqueous solutions of ammonium nitrite or urea nitrite are unstable. One of possible methods to concentrate solution and in […]

KÖKSAVFALLSKVARNAR FÖR UTSORTERING AV ORGANISKT HUSHÅLLSAVFALL FÖR RÖTNING OCH JORDBRUKSANVÄNDNING- AVSKILJNINGSSYSTEMET OCH RÖTNINGSPROCESSEN / Kitchen disposers for source-sorting of organic household waste for anaerobic digestion and agricultural reuse – the separation system and the anaerobic digestion process
In the newly built urban area Västra hamnen, in Malmö, Sweden, a new system for source-sorting of organic municipal waste, was constructed. The organic waste is disposed through a kitchen disposer, and is then led into a separate pipe, passes a cutting pump and is separated in a settling tank in the area. The material […]

DEN SVENSKA VATTENFÖRSÖRJNINGENS SÄKERHET MOT TERRORISM / Water supply security against terrorism in Sweden
The water supply system in Sweden consists mainly of large waterworks supplying most of the inhabitants with drinking water. This makes it an interesting target for terrorism. Along the water’s way from source to subscriber it passes a lot of dangerous spots where an attack is possible. The biological and chemical threats to the water […]
