Comparison of ozonation and distillation as treatment methods of recycled water for bioethanol fermentation process
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.
Biological degradation of spent de-icing fluids in a municipal wastewater treatment plant – Experiences and challenges
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.
Design and evaluation of nutrient removal plants for very low effluent concentrations
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.
