Recent Developments and Applications of the HYDRUS Computer Software Packages (2016, unknown): “For example, Bradford et al. (2002, 2003, 2004) evaluated the effects of attachment, straining, and exclusion on the fate and transport of colloids in saturated porous media. Gargiulo et al. (2007a,b, 2008) evaluated the effects of such factors as matrix grain size, water content, metabolic activity”
Straining of colloidal particles in saturated porous media (2006, result): “Several researchers have suggested that this failure to account for straining may be partially responsible for deviations between measured colloid retention rates and those predicted by physicochemical filtration theory [Bradford and Bettahar, 2005; Bradford et al., 2004, 2005, 2003, 2002; Li et a”
Upscaling of Stochastic Micro Model for Suspension Transport in Porous Media (2008, background): “The deviation was not explained in case of size exclusion particle capture (Bradford et al. 2002, 2003, 2004; Bradford and Bettahar 2006).”
Modeling microbial transport in porous media: Traditional approaches and recent developments (2007, background): “[16,17] illustrate how classical colloid filtration theory—which does not consider removal by straining—is not always appropriate for describing particle (microbe) transport in porous media.”
Transport and straining of E. coli O157:H7 in saturated porous media (2006, background): “…factors that are not included in filtration theory, such as straining (deposition of colloids in smaller pores and at grain-grain junction) [Bradford et al., 2002, 2003, 2004; Li et al., 2004; Tufenkji et al., 2004; Bradford and Bettahar, 2005; Foppen et al., 2005], soil surface roughness…”
HYDRUS: Model Use, Calibration, and Validation (2012, methodology): “The attachment/detachment features have been used recently in several studies to simulate the transport of viruses (e.g., Schijven and Šimůnek, 2002) colloids (Bradford et al., 2002, 2003, 2004), bacteria (Gargiulo et al., 2007a, 2007b), and nanoparticles (Torkzaban et al., 2010).”
Significance of straining in colloid deposition: Evidence and implications (2006, background): “…that deposition may occur as a result of physical factors that are not included in filtration theory, such as straining [Cushing and Lawler, 1998; Bradford et al., 2002, 2003, 2004, 2005, 2006a; Li et al., 2004; Tufenkji et al., 2004; Bradford and Bettahar, 2005, 2006; Foppen et al., 2005], soil…”
Straining of colloids at textural interfaces (2005, background): “…attachment behavior [Johnson and Elimelech, 1995], deposition of colloids in a secondary energy minimum [Redman et al., 2004; Tufenkji and Elimelech, 2005], and straining [Bradford et al., 2002, 2003, 2004; Li et al., 2004; Tufenkji et al., 2004; Bradford and Bettahar, 2005; Foppen et al., 2005].”
Pore‐scale visualization of colloid straining and filtration in saturated porous media using micromodels (2006, background): “Bradford et al. [2004] , Darnault et al. [2004], and Bradford and Bettahar [2005], also observed that the majority of colloid and oocyst retention occurred in the sand adjacent to the column inlet.”
