Abstract: Calcium sulfate solubility product and ion pair dissociation constant were measured in clean water, and these results were employed in tests with a pretreated coal conversion process wastewater to assess the tendency for ...

Abstract: The hydraulic characteristics of horizontally installed sorbent wick sampling devices were evaluated through wick tracer studies and laboratory soil column experiments to assess the influence of horizontal wick length and ...

Abstract: Experiments investigated the chemical capture and quantitative recovery of chlorinated hydrophobic organic compounds (HOCs) sampled from the pore-water of unsaturated soils with a new in situ sorbent wicking device. The ...

Abstract: The solubility of various aromatic solutes in miscible, polar solvent/water mixtures was investigated through experiment and interpreted through chemical thermodynamic models. Eighteen solute/solvent/water systems were ...

Abstract: Experiments and modeling activities are performed to determine the effect of polar solvent in the aqueous phase on the sorption of relatively hydrophobic solutes onto soils. The hydrophobic aromatic solutes generally display ...

Abstract: Hydrophobic organic compounds (HOCs) are modeled as being distributed between aqueous, micellar, and sorbent compartments in a soil/aqueous system containing nonionic surfactant micelles. The partitioning of HOC between ...

Abstract: Experimental data are compared with results from a model developed for nonionic surfactant solubilization of hydrophobic organic compounds (HOCs) in soil/aqueous systems. The model parameters that describe each of the major ...

Abstract: California has consistently altered natural water resources to provide water for its growing population and to support the fifth largest economy in the world. However, the old ways of coping with the California’s urban ...

Abstract: This paper reviews and extends understanding of evaporation/distillation as treatment for landfill leachate. Evaporation may produce condensate that is high quality and easier to dispose of than effluent from conventional ...
