Fecal Source Tracking in A Wastewater Treatment and Reclamation System Using Multiple Waterborne Gastroenteritis Viruses

Identifying fecal sources in a selected catchment reach using multiple source-tracking tools.

Given known limitations of current microbial source-tracking (MST) tools, emphasis on small, simple study areas may enhance interpretations of fecal contamination sources in streams. In this study, three MST tools-Escherichia coli repetitive element polymerase chain reaction (rep-PCR), coliphage typing, and Bacteroidales 16S rDNA host-associated markers-were evaluated in a selected reach of Plu...

Role of lime treatment in the removal of bacteria, enteric viruses, and coliphages in a wastewater reclamation plant.

Lime flocculation/sedimentation in the first process unit of a 4,500-m3/day wastewater reclamation plant reduced numbers of microorganisms extensively when operated at pH 11.2. The efficiency was much less at lower pH values, and some bacteria even multiplied at pH 9.6. Data on reduction in the number of microorganisms in the lime treatment and subsequent units indicate that inactivation by hyd...

Specific Options in Biological Wastewater Treatment for Reclamation and Reuse

A waterborne outbreak of gastroenteritis with multiple etiologies among resort island visitors and residents: Ohio, 2004.

BACKGROUND The implementation of treated municipal water systems in the 20th century led to a dramatic decrease in waterborne disease in the United States. However, communities with deficient water systems still experience waterborne outbreaks. In August 2004, we investigated an outbreak of gastroenteritis on South Bass Island, Ohio, an island of 900 residents that is visited by >500,000 person...

Producing Renewable Energy from Municipal Wastewater Treatment Using a Bio–electrochemical System

Concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (MFCs). In this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (ACMFC). The total duration of voltage generation by ACMFC was about 151.9 ±23.2 h. The maximum voltage produced from municipal wastewater treatment was 27...
