Monitoring of activated sludge settling ability through image analysis: validation on full-scale wastewater treatment plants.
In recent years, a great deal of attention has been focused on the research of activated sludge processes, where the solid-liquid separation phase is frequently considered of critical importance, due to the different problems that severely affect the compaction and the settling of the sludge. Bearing that in mind, in this work, image analysis routines were developed in Matlab environment, allow...
متن کاملDynamic Performance Analysis and Simulation of a Full Scale Activated Sludge System Treating an Industrial Wastewater Using Artificial Neural Network
Due to changeable nature of the industrial wastewaters, proper operation of an industrial wastewater treatment plant is of prior importance in order to keep the process stability at the desired conditions. In this mean, simulation of the treatment system behavior using artificial neural network (ANN) can be an effective tool. This paper evaluates long term performance and process stability of ...
متن کاملTetracycline resistance genes in activated sludge wastewater treatment plants.
The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. In the current study, wastewater treatment plants (WWTPs) were investigated as possible sources of tetr...
متن کاملContribution 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...
متن کاملMicrobial Community Structure of Activated Sludge in Treatment Plants with Different Wastewater Compositions
Activated sludge (AS) plays a crucial role in the treatment of domestic and industrial wastewater. AS is a biocenosis of microorganisms capable of degrading various pollutants, including organic compounds, toxicants, and xenobiotics. We performed 16S rRNA gene sequencing of AS and incoming sewage in three wastewater treatment plants (WWTPs) responsible for processing sewage with different origi...
