Occurrence of Clostridium difficile in two types of wastewater treatment plants

Journal of the Formosan Medical Association, 2015
Wastewater is a potential environmental source of Clostridium difficile, although a direct link with community-acquired C. difficile infection (CA-CDI) in humans has not yet been established. The present study was performed to determine the occurrence of

Characterization and evaluation of waste stabilization pond systems in Namibia

H2Open Journal, 2022
Waste stabilization ponds (WSP) exist worldwide to treat wastewater, especially in warm climates. They are characterized by simple operation and maintenance and over 50 years many WSP were built in urban communities in Namibia.

Waste Stabilization Ponds in France: An Overall Review

Water Science and Technology, 1987
In 1983 and 1986, surveys were conducted all over France on wastewater stabilization by “natural” ponds (lagoons), including an almost exhaustive inventory of the 1400 plants then operating. The statistical interpretation of collected data made it possible to analyse the spread of this technique, which became truly popular only ten years ago, and to ...

Characterizing phosphorus removal in passive waste stabilization ponds in Arctic communities

Arctic Science, 2016
A majority of communities in the Canadian territory of Nunavut rely on passive waste stabilization ponds (WSPs) for domestic wastewater treatment. Little research has been conducted on the treatment performance of these systems. Therefore, in response to

Cotreatment of sewage and septage in waste stabilization ponds

Water Science and Technology, 2002
A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge.
