Ionic liquids are widely studied as alternative solvents in organic synthesis and catalysis, in electrochemistry and the separation sciences; with their many applications they will soon be produced on an …
This paper discusses the influence of a wide range of anionic surfactant concentrations on activated sludge.
The main objective of the work was to show up that the fish processing industry in Nordic countries is producing according to technologies and methods that lead to the lowest possible impact to the environment.
This paper presents the results of the pilot-testing performed at both locations during the months of June and October 2015, respectively.
The aim of this study was to compare an evaporation and oxidation as a final stage of stillage treatment to recycle the treated water and use it in the ethanol process, namely the fermentation process.
Oslo Airport Gardermoen (OSL) is situated over a ground water reservoir, and collection and handling of spent de-icing fluids is therefore of major importance.
The paper presents typical design data for nitrification and denitrification in MBBRs, plus results from guarantee tests where a single train is operated at design load, as well as results from normal operation of the plants.
Out of six plants with nitrogen removal in Norway, four plants use the Moving Bed Biofilm Reactor (MBBR) process.
The results from Norwegian and North American pilot and small full scale technology assessment studies.
Full-scale testing demonstrated that the combined denitrification MBBR process can easily remove 90 % of total N at reasonable operating costs.
