The objective of this article is to review odour problems of wastewater treatment facilities and air emission treatment methods. The malodorous wastewater emissions consist of a complex mixture of substances with different properties. A screening of volatile organic and reduced sulphur compounds revealed very low concentrations of individual compounds (< 50 ppb), and only dimethyl […]

Urbanization of a watershed increases the volume and peak discharge of runoff. This paper shows how the use of low impact development (LID) best management practices (BMPs) influences site hydrology by comparing two newly established residential areas in Connecticut, USA. The watersheds were 2.0 and 1.7 ha for the traditional storm water management and LID […]

This article reports about flux measurements of CH4 and N2O from two types of constructed wetlands in south-eastern Norway, a free surface water (FSW) wetland polishing chemically treated municipal wastewater and a meso scale sub-surface flow (SSF) wetland receiving wastewater from a single domestic household. Fluxes of both gases had a large temporal and spatial […]
The objective of this study was to outline via a literature review reactive filter systems for small scale wastewater treatment. Phosphorus and ammonium sorption were considered. Different reactive filter materials have been studied in a laboratory, though few in full-scale. The lightweigh clay aggregate product Filtralite P and Nordkalk Filtra P are the materials most […]
Groundwater samples have been taken from two abandoned landfills Måsängen and Lackalänga in Kävlinge community. The results show that groundwater from Lackalänga is a mixture of reduced and oxidized waters due to above-normal iron, manganese and ammonium as well as high nitrate and sulfate concentrations. Meanwhile, high bicarbonate buffers the pH between 7.7 and 8. […]
