VULNERABILITY OF WASTEWATER TREATMENT PLANTS AND WASTEWATER PUMPING STATIONS TO EARTHQUAKES

A Framework for Modeling and Control of Wastewater Pumping Stations

In waste water pumping stations, centrifugal pumps driven by induction motors are used to transport the effluent collected from residential and commercial buildings to the treatment plants. Due to the varying nature of collected effluent rate, means of pump flow control should be applied. Recently, there is an engineering debate on either recommending frequency converters control or on-and-off ...

Titrimetric Biosensing of Biological Wastewater Treatment Plants

The development of titrimetric sensor applications to monitor biological wastewater treatment processes is shortly described, and the measurement principle (based on a pH controller) is illustrated. 3 applications that were developed during the past years are used to illustrate the capabilities of titrimetric sensors. The ammonium and the nitrate concentration can be measured to monitor the nit...

Model Based Control of Wastewater Treatment Plants

In the contribution a (non-exhaustive) overview is given on the use of mathematical models in control systems of wastewater treatment plants. As a starting point, the four building blocks of any controlled process are used, 1) the process itself, 2) the actuators that allow manipulation of the process, 3) the control algorithm that calculates a proper action for disturbance rejection or setpoin...

Fuzzy Design of Wastewater Treatment Plants

Life-Cycle Assessment of Wastewater Treatment Plants

This thesis presents a general model for the carbon footprints analysis of wastewater treatment plants (WWTPs), using a life cycle assessment (LCA) approach. In previous research, the issue of global warming is often related to traditional industries with high carbon dioxide (C0 2) emissions, such as power plants and transportation. However, the analyses of wastewater treatment plants (WWTPs) h...
