Abstract: Powdered bentonite organoclay was used to remove oil from water in this study. The oil-in-water emulsions used were standard mineral oil (SMO), Kutwell45 (KUT45), and Valcool (VAL) (two cutting oils), refinery effluent ...

Abstract: Bentonite is known to adsorb toxic metal ions from aqueous solutions. In this study bentonite was immobilized in a polymer matrix of polysulfone in the form of spherical beads to remove cadmium and copper ions. For this ...

Abstract: Nitrate concentrations in surface water and especially in ground water have increased in Canada, the United States, Europe, and other areas of the world. This trend has raised concern because nitrates cause methemoglobinemia ...

Abstract: Phosphorus is a key nutrient responsible for eutrophication. Conventional activated sludge process (ASP) removes approximately 30 to 40% phosphorus. Additional phosphorus removal has been achieved by incorporating an ...

Abstract: A laboratory study was conducted to study inert solute transport in a heterogeneous field. Twenty-one relatively undisturbed soil columns were sampled from a field plot, and chloride tracer tests were carried out in these ...

Abstract: Enhanced biological phosphorus removal is a two-step process. The sequence of anaerobic environment followed by aerobic environment is essential for selection of biological phosphorus-removing culture. Anaerobically, ...
