Optimizing Wastewater Treatment

ثبت نشده
چکیده

In many urban situations, both the municipal sewage system and industrial wastewater treatment are inadequate. A municipal sewage network may be in place, but coverage is usually incomplete, and the level of treatment provided is inadequate. Even where reasonable treatment facilities exist, poor maintenance and operation often result in failure to meet design effluent levels. In such circumstances, management of industrial wastewater discharges is also frequently poor, with uncontrolled discharges of untreated effluent to surface waters (through often drainage or stormwater channels) or to the sewer system. The result is high levels of water pollution. It is not uncommon for streams or water bodies to be almost or completely anaerobic and heavily polluted with organic compounds, pathogens, and heavy metals.

Model predictive control for the self-optimized operation in wastewater treatment plants: Analysis of dynamic issues

−−This paper describes a procedure to find the best controlled variables in an economic sense for the activated sludge process in a wastewater treatment plant, despite the large load disturbances. A novel dynamic analysis of the closed loop control of these variables has been performed, considering a nonlinear model predictive controller (NMPC) and a particular distributed NMPC-PI control struc...

Contribution to dynamic simulation of activated sludge wastewater treatment plants

In Portugal, many wastewater treatment plants are presently operated according to predetermined schemes, with few concerns to variations of the activated sludge process and without optimizing its performance to achieve a better effluent quality. Little attention has been given to the activated sludge models as powerful tools for wastewater treatment process understanding, design, control and op...
