The decimal elimination capacity (DEC) of slow sand filters (SSF) for viruses, bacteria and oocysts of Cryptosporidium has been assessed from full-scale data and pilot plant and laboratory experiments. DEC for viruses calculated from experimental data with MS2-bacteriophages in the pilot plant filters was 1.5-2 log10. E. coli and thermotolerant coliforms (Coli44) were removed at full-scale and in the pilot plant with 2-3 log10. At full-scale, Campylobacter bacteria removal was 1 log10 more than…

Behaviour of Somatic and F-specific Coliphages in Slow Sand Filter

Behaviour of somatic and F-specific coliphages, as model viruses, in a full-scale slow sand filtration (SSF) treatment plant of Japan was investigated through enumeration with the conventional

Removal of pepper mild mottle virus by full-scale microfiltration and slow sand filtration plants

It is important to evaluate the removal of enteric viruses by drinking water treatment processes so that viral infection risk can be assessed and managed. However, evaluating the removal of enteric

Transport of MS2 Phage, Escherichia coli, Clostridium perfringens, Cryptosporidium parvum and Giardia intestinalis in a Gravel and a Sandy Soil •

To define protection zones around groundwater abstraction wells and safe setback distances for artificial recharge systems in watertreatment, quantitative information is needed about the removal of

The control of waterborne pathogenic bacteria in fresh water using a biologically active filter

This work demonstrates that biofilter systems can be used to significantly reduce waterborne pathogenic bacteria within fresh water, using biofiltration for the management of waterborne bacterial pathogens in water supplies.

Influence of design and operating conditions on the removal of MS2 bacteriophage by pilot-scale multistage slow sand filtration

This paper summarizes findings from sixteen MS2 bacteriophage (MS2) challenge tests on biologically mature pilot-scale slow sand filters, conducted at varying water temperatures ( 20°C), two



Removal of sulphite-reducing clostridia spores by full-scale water treatment processes as a surrogate for protozoan (oo)cysts removal

At eight full-scale water treatment plants in the Netherlands the removal of spores of sulphite-reducing clostridia (SSRC) was determined. By sampling and processing large volumes of water (1 up to

Removing Giardia and Cryptosporidium by Slow Sand Filtration

Findings suggest that Cryptosporidium may not be adequately removed from a contaminated source water under very cold operating conditions or if the filtration plant does not comply with accepted design standards.


Evaluation of a blood-free, charcoal-based, selective medium for the isolation of Campylobacter organisms from feces

It is confirmed that charcoal is an effective substitute for blood in media for growing campylobacters, and that CSM is a highly effective blood-free selective medium for isolating C. jejuni and C. coli from stools.

Removing Giardia Cysts With Slow Sand Filtration

Pilot-plant studies were undertaken to determine the efficiency of slow-rate sand filters in removing Giardia cysts and other substances, and found this technology is especially appropriate for small water systems.

The use of Preston enrichment broth for the isolation of ‘thermophilic’ campylobacters from water

SUMMARY The application of Preston enrichment broth to isolation of ‘thermophilic’ campylobacters from water has been investigated. Enrichment substantially increased the yield of such organisms. The
