Quantitative monitoring of an activated sludge reactor using on-line UV-visible...
Sarraguça, M. C.; Paulo, A.; Alves, M. M.; Dias, A. M. A.; Lopes, J. A.; Ferreira, E. C.The performance of an activated sludge reactor can be significantly enhanced through use of continuous and real-time process-state monitoring, which avoids the need to sample for off-line analysis and to use chemicals. Despite the complexity associated with wastewater treatment systems, spectroscopic methods coupled with chemometric tools have been shown to be powerful tools for bioprocess monitoring and contro...
Surveying an activated sludge reactor using online UV-visible and NIR spectrosc...
Paulo, A.; Dias, A. M. A.; Sarraguça, M. C.; Lopes, J. A.; Alves, M. M.; Ferreira, E. C.The performance of activated sludge reactors can be enhanced by the ability to monitor the status of the process without the need for chemicals addition or complex calibration procedures. Nowadays automation is still limited by poor sensor performance and high maintenance costs. Spectroscopic methods associated with chemometrics are being presented as a powerful tool for process monitoring and control. Once imp...
