Fecal coliform population dynamics associated with the thermophilic stabilization of treated sewage sludge.

Journal of Environmental Monitoring, 2012
The inactivation of fecal coliforms in anaerobic batch reactors has been investigated at the thermophilic temperatures of 50, 55 and 60 °C. Throughout inactivation experiments at each temperature, individual colonies were isolated and identified by 16S ...

Extended Acid Digestion for Inactivation of Fecal Coliforms

Water Environment Research, 2006
The objective of this research was to establish a correlation between inactivation of fecal coliforms caused by organic acids in their un‐ionized form in batch acid digesters and semicontinuously fed acid digesters at both mesophilic (38°C) and low‐mesophilic (24°C) temperatures. Batch acid digesters achieved a U.S.

REGROWTH OF FECAL COLIFORMS IN CLASS A BIOSOLIDS

Proceedings of the Water Environment Federation, 2004
Eight types of Class A biosolids were tested for fecal coliform (FC) reactivation and/or regrowth at 20, 35, and 50?C for 21 days. Growth of FC did not occur at 20 or 50?C, but it was observed in two samples incubated at 35?C after a lag period of 48 hours.

Fecal coliform removal in a sulfate reduction, autotrophic denitrification and nitrification integrated (SANI) process for saline sewage treatment.

Water Science and Technology, 2010
The Sulfate Reduction, Autotrophic Denitrification, Nitrification Integrated (SANI) process has been specially designed to treat saline wastewater. In the process no biological excess sludge is produced. SANI process also has the added advantages of cost

Fecal coliform densities in a Western watershed

Water, Air, and Soil Pollution, 1982
This paper describes the areal distribution of fecal coliform densities within the stream system of the South Platte River basin in Colorado. Low densities, e.g., 0 to 99 fecal coliforms per 100 ml, were found in mountain streams, while higher densities, e.g., 10000 to 100000 and above were found in plains streams. About 49 % of the plains stations and

Escherichia coli: The Fecal Coliform

1977
The use of Escherichia coli as an indicator of fecal pollution and the significance of its presence in surface waters was reviewed. A minidefinition which identifies this organism at least 95 percent of the time was proposed. Membrane filtration and most probable number methods for the enumeration of E. coli were discussed.

Significance of fecal coliform and fecal streptococcus in water pollution monitoring

Acta Academiae Medicinae Wuhan, 1982
The experimental results showed that the fecal coliform (FC) to fecal streptococcus (FS) ratio (FC/FS) in the human feces and in warm-blooded animal feces were rather different. FC/FS ratio in the human feces was greater than 7.0, and in warm-blooded animal feces was less than 1.0.

Coliform Group and Fecal Coliform Organisms as Indicators of Pollution in Drinking Water

Journal AWWA, 1960
The presence of any type of coliform organism in treated drinking water suggests either inadequate treatment or access of undesirable materials to the water after treatment. Although there are some differences between strain and subgroup organisms with regard to survival under natural conditions and resistance to chlorination, in general all the ...

Surface streaking and fecal coliform levels

Canadian Journal of Civil Engineering, 1984
The measurement of the dilution and die-off of fecal coliforms in high velocity, wind-generated surface currents is discussed. The dispersion in the streaks is similar to that found in oil slicks. It was found that the high velocities and slower growth rate of the dispersion in the streaks resulted in fecal coliform levels about four times higher than

Artificial Intelligence-Based Inductive Models for Prediction and Classification of Fecal Coliform in Surface Waters

, 2008
This paper describes the use of inductive models developed using two artificial intelligence (AI)-based techniques for fecal coliform prediction and classification in surface waters.
