TL;DR: In this paper, the authors evaluated the greenhouse gas (GHG) emissions from sewage sludge treatment methods and created a calculator suitable for the Northern Finland context, which can be used to select the locally most suitable method.

TL;DR: Column tests revealed that both HCl-P and AQM PalPower M10 were able to remove metals, although some leaching was witnessed, especially As from AQm Pal power M10, which may restrict the possibilities of using such small particle size peat material in a filter-type passive system.

TL;DR: In this paper, the long-term treatment performance of peatland-based treatment wetlands and factors affecting this performance were analyzed. But the results indicated that not all the areas potentially suitable in DOFAs for water purification are yet being used efficiently.

TL;DR: The influence of seasonally frozen ground (SFG) on water, energy, and solute fluxes is important in cold climate regions as mentioned in this paper, however, the reported hydrological effects of SFG remain contradictory and appear to be highly site and event-specific.

TL;DR: Evaluating the suitability of selected sorbents for use in continuous-flow continuous stirred tank reactors (CSTR) followed by sedimentation in laboratory and in situ pilot-scale experiments found higher metal removal was achieved from samples with higher initial metal concentrations.
