The aim of this paper is to describe the state-of-the art computer-based techniques for data
analysis to improve operation of wastewater treatment plants. A comprehensive review of …

Traditionally, the detection of pathogens in water, wastewater, and other environmental
samples is restricted by the ability to culture such organisms from complex environmental …

The operation of modern wastewater treatment plants (WWTPs) is driven by activated sludge
microbiota, a complex assemblage of trophically interacting microorganisms. Microbial …

An objective index, the Sludge Biotic Index (SBI), based on the microfauna associated with
activated-sludge mixed liquor, has been devised to monitor activated-sludge plant …

Positive effects of protozoa on carbon mineralization by bacteria are considered here
specifically in the context of waste-water treatment. The following effects are reviewed:(1) …

The aim of this study is to determine the relationship between the ciliate populations density
and effluent quality in activated sludge plants. A total of 231 samples taken at three activated …

A quantitative survey of the protozoan microfauna at 17 activated sludge plants, has been
carried out during a period of 1 year. The occurrence and abundance of the most important …

Protozoan predators form an essential component of activated sludge communities that is
tightly linked to wastewater treatment efficiency. Nonetheless, very little is known how …

Microorganisms present in wastewater treatment plants are responsible for effluent water
quality. In activated sludges, biotic components are represented by decomposers (bacteria …

Ciliated protozoa present in ten activated sludge plants at Madrid (Spain) were identified.
The abundance of key groups of ciliates was determined at each plant; attached ciliates …
