Adsorption of Pesticides by Clay Minerals
The rate and equilibrium of adsorptions of DDT, dieldrin, and heptachlor by illite, kaolinite, and montmorillonite from aqueous pesticidal solutions are evaluated using the batch technique...

Dispersion and Adsorption in Porous Media Flow
A mathematical analysis is presented of the phenomenon of simultaneous dispersion and adsorption of a solute in porous media flow. Mathematical solutions are given that refer to the case...

Surface Area Measurement and Absorption of Soils
Specific surface and mineralogical composition of soils are two main factors affecting ABS adsorption. Three groups of typical aquifer soils chosen for this study are sandstone, limestone,...

Equilibria and Capacities for Adsorption on Carbon
Laboratory investigations show that the ultimate capacity of granular carbon for adsorption of biochemically-resistant organic substances from dilute solution after a sufficient period...

Kinetics of Adsorption on Carbon from Solution
Laboratory investigations show that rates of adsorption of persistent organic compounds on granular carbon are quite low. Intraparticle diffusion of solute appears to control the rate...

Fluorescent Tracers for Dispersion Measurement
Laboratory tests on the behavior of the fluorescent dyes rhodamine B, Pontacyl Brilliant Pink B, and fluorescein in surface waters of variable quality indicate that Pontacyl Brilliant...

Transient Operation of the Trickling Filters
Trickling filter consists of column filled with loosely packed solid covered with biological slime; fluid (sewage liquor) is passed through column, and fluid and slime exchange mass; mechanism...

Adsorption and Assimilation in Activated Sludge
Activated sludge is widely used for stabilization of sewage and industrial wastes; evidence is presented to show that soluble organic matter is removed from solution by assimilation while...
