Research on a soft measurement model of sewage treatment based on a case-based reasoning approach
In this paper, the measurement of biochemical oxygen demand (BOD) in a wastewater treatment process is analyzed and an intelligent integrated prediction method based on case-based reasoning (CBR) is proposed in order to overcome difficulties. Due to the fact that there are many factors that influence the accuracy of the prediction model, the radial basis function, which is a neural network ...

Evaluation of virus reduction efficiency in wastewater treatment unit processes as a credit value in the multiple-barrier system for wastewater reclamation and reuse
The virus reduction efficiency of each unit process is commonly determined based on the ratio of virus concentration in influent to that in effluent of a unit, but the virus concentration in wastewater has often fallen below the analytical quantification limit, which does not allow us to calculate the concentration ratio at each sampling event. In this study, left-censored datasets of ...

mini LoP improved performance - Case Study
Meeting very stringent total phosphorous requirements is a challenge for a treatment plant that is receiving wastewater from a dairy process. With a total phosphorous limit less than 100 ppb, a reliable, precise, highly accurate ortho-phosphorous measurement is required to monitor and control the tertiary phosphorous removal process. Small town plants in the upper Midwest commonly encounter this ...

PR04 - Can ICA save costs?
Untitled Document Ofwat expects Water Companies in England and Wales to make savings on their operating costs by achieving greater efficiency, but further belttightening can’t offer much more scope without putting performance at risk. ICA (instrumentation, control and automation), on the other hand, offers real potential for increased efficiency if it is ...

Fast and reliable analysis of wastewater and sludges with a scanning array ICP emission spectrometer
Wastewater and sludge analyses generally require the determination of many elements and are economically performed using ICP-OES, due to the speed and robustness of this technique. Several ICP-OES methods are available for this determination including EPA method 200.7 (1). In the USA, DIN 38 406 E22 (2) in Germany, or ISO 11885 (3) on a global scale. For this type of application, the ...

Genes encoding tetracycline resistance in a full-scale municipal wastewater treatment plant investigated during one year
Tetracycline-resistant bacteria and genes encoding tetracycline resistance are common in anthropogenic environments. We studied how wastewater treatment affects the prevalence and concentration of two genes, tetA and tetB, that encode resistance to tetracycline. Using real-time polymerase chain reaction (PCR) we analysed wastewater samples collected monthly for one year at eight key-sites in a ...
