Objectives of this work are to investigate effects of pH and ionic strength (IS) on virus transport in saturated soil and to develop a quantitative relationship for these effects. A series of 50-cm column experiments with clean quartz sand under saturated conditions and with pH values of 5, 6, 7, 8, and IS values of 1, 10, and 20 mM were conducted. Bacteriophage PRD1 was used as a model virus. Applying a one-site kinetic model, attachment, detachment, and inactivation rate coefficients were…

hage adsorption to bacteria in the light of the electrostatics : A case study using . coli , T 2 and flow cytometry
TLDR
Flow cytometry was able to detect weakly adsorbed phage that remained undetected using classical centrifugation-based methods and this allowed us to show that increasing ionic strength enhances the phage adsorption to its bacterial host with an extremely low detection limit.

Transport of Escherichia coli phage through saturated porous media considering managed aquifer recharge
TLDR
The effects of hydrodynamic and hydrogeochemical conditions on the transportation of the colloidal virus considering managed aquifer recharge were systematically investigated and a one-dimensional transport model was established to quantitatively describe the virus transport in saturated porous medium.

MS-2 AND POLIOVIRUS TRANSPORT IN POROUS MEDIA : HYDROPHOBIC EFFECTS AND CHEMICAL PERTURBATIONS
TLDR
Results show that viruses experience reversible attachment/detachment, that large chemical perturbations are needed to induce rapid virus detachment, and that viruses should be quite mobile in sandy porous media.
Removal of Viruses by Soil Passage: Overview of Modeling, Processes, and Parameters
TLDR
Enhanced or reduced inactivation is found to be virus-specific and almost independent of adsorption, and temperature is the most important factor that influences virus inactivation.
Virus Transport in Saturated and Unsaturated Sand Columns
The transport of viruses in unsaturated porous media has been a subject of great interest in recent years because of the enhanced removal of these microorganisms compared with saturated conditions.…

Delineating the Specific Influence of Virus Isoelectric Point and Size on Virus Adsorption and Transport through Sandy Soils
TLDR
The data suggest that the isoelectric point of a virus is the predetermining factor controlling viral adsorption within aquifers, and that when virus particles are more than 60 nm in diameter, viral dimensions become the overriding factor.
Modeling Virus Adsorption in Batch and Column Experiments
TLDR
Under these conditions, bacteriophage φX174 appears to behave more conservatively than more negatively charged viruses, and may then be a better choice as a relatively conservative tracer for virus transport through the subsurface.
Deposition Kinetics of Two Viruses in Packed Beds of Quartz Granular Media
TLDR
The removal of waterborne viruses by packed bed filtration was examined using a model system consisting of two different bacteriophages (MS2 and λ) and saturated beds of ultrapure quartz grains, suggesting that electrostatic repulsive forces effectively dominate the filTration dynamics of λ.
KINETIC ANALYSIS OF VIRUS ADSORPTION AND INACTIVATION IN BATCH EXPERIMENTS
TLDR
A simple first-order kinetic theory is presented which accounts for many of the complicated interactions that can occur when viruses contact an adsorbent in a batch system and suggests that the proposed approach offers a powerful alternative to conventional methods for studying virus adsorption at the solid-liquid interface and for predicting the potential mobility and fate of viruses in porous media.
