Analysis of Bacterial Deposition on Metal (Hydr)oxide-Coated Sand Filter Media

Processes in Pathogenic Biocolloidal Contaminants Transport in Saturated and Unsaturated Porous Media: A Review

“…Despite these efforts, the mechanisms governing the adhesion of bacterial cells onto sediment are not fully understood. Application of DLVO theory to explain bacterial adhesion to solid substrate has only been successful for a limited number of strains and species (Poortinga et al 2001(Poortinga et al , 2002Baygents et al 1998;Truesdail et al 1998). In some cases, attempts have been made to reconcile discrepancies between DLVO predictions and observations by including non DLVO forces, such as Lewis acid-base interactions, into the so-called extended DLVO calculations (Jeremy et al 2004;Azerdo et al 1999.…”

“…Furthermore, subsequent oxidation of Mn(II) by the intact biofilms bound to the crystal surfaces did not diminish adhesion once the biofilms were formed. Adhesion is likely mediated by favorable bonding interactions (e.g., cationic proteins, hydrogen bonding, hydrophobic interaction, surface roughness) between bacterial biomolecules and the substrata that overcome the repulsion induced by net negative charge of bacterial and crystal surfaces (Marshall et al 1971;Truesdail et al 1998;Deo et al 2001;Appenzeller et al 2002).…”

Surface forces: Surface roughness in theory and experiment

“…While the limitations of the theory are well known, [3][4][5] the theory has nevertheless provided insight across a vast range of fields, including agriculture and food science, [6][7][8] mineral and oil extraction, 9,10 and filtration 11 and biology. [12][13][14] One limitation of the theory is that it is built upon the assumption of ideally smooth surfaces.…”
