This study investigated whether colloid-sized particles can enmesh and protect viruses from
254-nm ultraviolet (UV) light and sought to determine the particle characteristics (eg size …

Aims: To investigate the impact of iron particles in groundwater on the inactivation of two
model viruses, bacteriophages MS2 and T4, by 254‐nm ultraviolet (UV) light. Methods and …

UV disinfection of viruses frequently leads to tailing after an initial exponential decay.
Aggregation, light shielding, recombination, or resistant virus subpopulations have been …

Numerous studies have shown that the efficacy of ultraviolet (UV) disinfection can be
hindered by the presence of particles that can shield microorganisms. The main objective of …

This study assessed the impact of suspended particles on both ultraviolet (UV) dose
transmission and spectrophotometric absorbance measurement for unfiltered raw water with …

This study examined the potential for naturally occurring particles to protect indigenous
coliform from ultraviolet (UV) disinfection in four surface waters. Tailing in the UV dose …

Particles in water sources may be classified in various groups such as living vs. non-living,
nano vs. sub-micron to micron sized and mineral vs. organic. Living particles for example …

Suspended particles in wastewater play two roles in ultraviolet (UV) disinfection: they absorb
and scatter UV light, and they harbor bacteria and protect them from the light. These effects …

This bench-scale study investigated the passage of particle-associated bacteriophage
through a dual-media (anthracite-sand) filter over a complete filter cycle and the effect on …

It is well‐recognized that changes in ultraviolet (UV) absorbance or significant
concentrations of amorphous biological wastewater solids in a water matrix can affect UV …
