TL;DR: A combined system of biological and chemical treatments was found to be more effective for the complete removal of nitrate from groundwater.

TL;DR: The analytical solution could successfully describe the kinetic adsorption of aqueous benzene in the batch reaction system, showing a fast instantaneous adsor adaptation followed by a slow rate-limiting adsorbed and a final long constant adsorptive stage.

TL;DR: Column experiments revealed that both peak concentrations and mass recoveries of bacteria were lower than those of a conservative tracer KCl when deionized water was used as leaching water for all ranges of pore-water velocity, and the ionic strength markedly influenced bacterial deposition.

TL;DR: The influence of organic carbon content at various flow rates on the transport of aqueous benzene in a sandy soil was investigated in this article, where three types of convection-dispersion transport model (equilibrium, reversible two-site, and reversible-irreversible sorption) were used to determine the appropriate model that best described the observed benzene transport.

TL;DR: In this article, the irreversible loss from the solution to the sorption sites was derived from a kinetic batch sorption test conducted for an appropriate soil-to-solution ratio to reflect the flow conditions imposed on a column test.
