Abstract: The objective of the paper is to investigate the effect of temperature and caustic soda concentration in the bauxite digestion process on the settling behavior and the physical, chemical, and mineralogical characteristics ...

Abstract: Bentonite, forest soil, and spruce bark were submitted to batch adsorption testing, leaching cell testing, and selective sequential extractions (SSEs) to investigate the heavy-metal compatibility of clay barriers and the ...

Abstract: A multicomponent reactive solute-transport model was used to study the migration of dissolved heavy metals (Cd

Abstract: An innovative system was developed to enhance electrokinetic extraction of heavy metals from contaminated soils. The system consists of a layer that was continuously flushed with nitric acid at pH 3 near the cathodic region ...

Abstract: One-stage autothermal thermophilic aerobic digestion (ATAD) is a promising process for sewage sludge stabilization. This study investigated semicontinuous operation in simulated one-stage ATAD digesters and analyzed the ...
