Effective removal of Cryptosporidium parvum oocysts by granular filtration requires the knowledge of oocyst transport and deposition mechanisms, which can be obtained based on real time microscopic observation of oocyst transport in porous media. Attachment of oocysts to silica surface in a radial stagnation point flow cell and in a micromodel, which has 2-dimensional (2-D) microscopic pore structures consisting of an array of cylindrical collectors, was studied and compared. Real time…

Role of collector alternating charged patches on transport of Cryptosporidium parvum oocysts in a patchwise charged heterogeneous micromodel.
TLDR
Differences between experimentally determined overall η for charged heterogeneous collectors and those predicted by a patchwise geochemical heterogeneous model were observed, which can be explained by the model's lack of consideration for the spatial distribution of charge heterogeneity on the collector surface.
Flagella-mediated differences in deposition dynamics for Azotobacter vinelandii in porous media.
TLDR
Observations in all three setups suggested flagella affect deposition dynamics and, in particular, result in greater sensitivity to ionic strength.
Swimming Motility Reduces Deposition to Silica Surfaces.
The transport and fate of bacteria in porous media is influenced by physicochemical and biological properties. This study investigated the effect of swimming motility on the attachment of cells to…
Effects of Soil Type and Cover Condition on Cryptosporidium parvum Transport in Overland Flow
Overland transport kinetics of pathogens is controlled, in large part, by soil and vegetation. With an increasing number of concentrated animal operations, there is becoming a greater need to dispose…
MS2 bacteriophage reduction and microbial communities in biosand filters.
TLDR
This study provides the first insight into microbial community structures that may play a role in MS2 reduction in BSF ecosystems by evaluating the role of physical and biological filter characteristics on the reduction of MS2 bacteriophage in biosand filters.
Visualization of transport and fate of nano and micro-scale particles in porous media: modeling coupled effects of ionic strength and size
In this investigation, the single collector removal efficiency (η) of three latex nanoparticles differing in size (20, 200, 2000 nm) is presented for a 2-D micromodel system. The η for each collector…
Nanowires of Geobacter sulfurreducens Require Redox Cofactors to Reduce Metals in Pore Spaces Too Small for Cell Passage.
TLDR
The results discount electron shuttling by dissolved flavins, and instead support their role as bound redox cofactors in electron transport from nanowires to metal oxides, and show that upon addition of a soluble electron shuttle, reduction extends beyond the reported nanowire length up to 40 μm into a layer of birnessite.
Thermoplastic Micromodel Investigation of Two-Phase Flows in a Fractured Porous Medium

Straining, attachment, and detachment of cryptosporidium oocysts in saturated porous media.
TLDR
Experimental and modeling studies were undertaken to examine the roles of attachment, detachment, and straining on oocyst transport and retention, and a more physically realistic description of the data was obtained by modeling attachment, detachments, andstraining.
Adhesion kinetics of viable Cryptosporidium parvum oocysts to quartz surfaces.
TLDR
It is proposed that specific binding of calcium ions to the oocyst surface functional groups results in charge neutralization and conformational changes of surface proteins that significantly reduce electrosteric repulsion.
Spatial distributions of Cryptosporidium oocysts in porous media: evidence for dual mode deposition.
TLDR
Oocyst deposition behavior is shown to deviate from predictions based on classical colloid filtration theory in the presence of repulsive (unfavorable) colloidal interactions, having important implications for predictions of oocyst transport in subsurface environments, where repulsive electrostatic interactions predominate.
Transport of Cryptosporidium oocysts in porous media: role of straining and physicochemical filtration.
TLDR
The results of this study indicate that irregularity of sand grain shape contributes considerably to the straining potential of the porous medium, and both straining and physicochemical filtration are expected to control the removal of C. parvum oocysts in settings typical of riverbank filTration, soil infiltration, and slow sand filtrations.
Cryptosporidium oocyst surface macromolecules significantly hinder oocyst attachment.
TLDR
After treatment with proteinase K, the oocysts no longer experienced electrosteric repulsive forces, and their deposition kinetics followed the general behavior predicted by DLVO theory.
Role of surface proteins in the deposition kinetics of Cryptosporidium parvum oocysts.
TLDR
A radial stagnation point flow system was used to investigate the influence of Cryptosporidium parvum surface properties on oocyst deposition kinetics onto solid surfaces and it is hypothesized that formalin and heat treatments alter the structure of surface proteins and thus reduce steric repulsion.
Deposition of Cryptosporidium Oocysts in Streambeds
TLDR
Investigation of the deposition of suspended Cryptosporidium parvum oocysts in streambeds demonstrates that hydrodynamic interactions between an overlying flow and a sediment bed cause oocyst to accumulate in the sediments and reduce their concentrations in the surface water.
Role of divalent cations on deposition of Cryptosporidium parvum oocysts on natural organic matter surfaces.
TLDR
The deposition and ICP results suggested that inner-sphere complexation of Ca(2+) with carboxylate groups on bothSRNOM and oocyst surfaces enhanced deposition of oocysts on a SRNOM surface.
Coupled factors influencing the transport and retention of Cryptosporidium parvum oocysts in saturated porous media.
Association of Cryptosporidium parvum with Suspended Particles: Impact on Oocyst Sedimentation
TLDR
It is believed that the ubiquitous association of C. parvum oocysts with suspended particles enhances the sedimentation of oocyst in natural waters and that this interaction should generally be considered when predicting the migration of pathogens in the environment.
