Dynamics in Wastewater Treatment

WaRP: A Reactive Planner Integrated in an Environmental Decision Support System fo Wastewater Treatment Plant Management

In this paper we present an environmental decisionsupport system (named DAI-DEPUR+) and a reactive linear planner (named WaRP), and their application to the wastewater domain. The environmental decision-support system: receives and processes onand off-line information about a wastewater treatment process. uses this information for selecting and revising models of the treatment-system dynamics. ...

Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. Although the main principle of the process has been the same since its usage began 100 years ago, there has been a continuous development and moder...

Dynamics in wastewater treatment: A framework for understanding formal constructs in complex technical settings

Based on the study of unskilled work in a Danish wastewater treatment plant, the problem of formalisation of work is discussed and extended to technical processes Five symmetrical levels of dynamics in complex technical work arrangements are proposed as a tool for understanding the limits of formalisation and for designing formal constructs in such settings. The analysis is based on concepts of...

New Developments in Mixing, Coagulation, Flocculation and Flotation for Industrial Wastewater Pretreatment

Solid/liquid separations are a mature technology area and few new developments occurred in seventies and eighties. However, last decade witnessed appearance of a significant number of new innovative systems in this field. (Rubio et al., 2002) This paper describes new developments in mixing, coagulation, flocculation and flotation systems for industrial wastewater treatment. (Ross et al., 2000; ...
