TL;DR: The feasibility of soil washing for decontaminating a silty sand spiked with cadmium, chromium, lead, and zinc was evaluated in laboratory-scale batch and column experiments, and a mixture of the two reagents may provide an economically optimum solution for certain contaminated soils.

TL;DR: Adsorption is a fundamental process for separating inorganic and organic contaminants from waters and waste-waters Mathematical process models can facilitate the design of full-scale systems simply by reducing the number of pilot-scale tests required to evaluate various operating conditions and design parameters as mentioned in this paper.

TL;DR: In this paper, three laboratory-scale biofilter columns were operated for 82 days to investigate the removal of benzene, toluene, ethylbenzene, and o -xylene (BTEX) from a waste gas stream.

TL;DR: In this article, an iron-bearing material deriving from surface finishing operations in the manufacturing of cast-iron components demonstrates potential for removal of heavy metals from aqueous waste streams.

TL;DR: In this article, the impacts of total metal concentration, ionic strength and pH on adsorption capacity are quantified in terms of the Freundlich isotherm equation for isotherms conducted at a single initial pH value.
