Journal ArticleDOI
Coupled factors influencing concentration-dependent colloid transport and retention in saturated porous media.
TL;DR: The concentration effects were found to be largely independent of input colloid mass during filling of retention sites, and retention profiles for IS = 31 mM conditions were increasingly nonexponential at lower values of Ci, whereas the observed concentration effect was largely eliminated as retention locations became filled.
Journal ArticleDOI
Analysis of Steroid Hormones in a Typical Dairy Waste Disposal System
TL;DR: Increasing the piling time of solid wastes and increasing the residence time of wastewater in sequencing lagoons are suggested to be economical and efficient agriculture practices to extend the degradation time of hormone contaminants and thereby reduce the hormone load to the environment.
Journal ArticleDOI
Straining of colloids at textural interfaces

TL;DR: In this article, Saturated column studies were undertaken to characterize the straining behavior of negatively charged latex colloids (1.1 and 3.0 μm) at textural interfaces.
Journal ArticleDOI
A theoretical analysis of colloid attachment and straining in chemically heterogeneous porous media.
TL;DR: A balance of applied hydrodynamic and resisting adhesive torques was conducted over a chemically heterogeneous porous medium to determine the fraction of the solid surface area that contributes to colloid immobilization (S(f)*) under unfavorable attachment conditions.
Journal ArticleDOI
Critical role of surface roughness on colloid retention and release in porous media.
TL;DR: Results demonstrated that the density and height of NSR significantly influenced the interaction energy parameters and consequently the extent and kinetics of colloid retention and release, and yielded a much weaker primary minimum interaction compared with that of smooth surfaces.
