Wastewater treatment quantification

Effects of wastewater treatment plant discharge on the ecology of bacterial communities in the sediment of a small, low-gradient stream in South Australia, and the quantification of genes involved in the biogeochemical cycling of carbon and nitrogen [167]... 

Marcomini et al. [25] performed the protonation of the carboxylic groups of the SPC. This technique termed ion suppression effect chromatography enabled the individual elution of the SPC contained in a primary sludge from a wastewater treatment plant. The quantification of the SPC was performed under the assumption that the signals detected by fluorescence before the elution of the LAS (with the exception of NPEC) correspond solely to SPC.

Colloids used for the study (List I) were defined in terms of their size and shape to allow reproducible quantification of aggregate numbers and sizes. As much as possible, the aggregates should resemble the solids encountered in water and wastewater treatment as to size, density, and chemical characteristics like surface charge and its change with variations in the composition of the suspending medium.

This paper is structured as follows in the first part, the characteristics of the natural phenomenon are described and a brief section has been devoted to the description of a typical wastewater treatment in the second part a methodology for the quantification of the critical thicknesses of volcanic ash accumulated on the screens is proposed finally the application to a case-study, which is the area surrounding Mt. Etna is shown. 

Retrospective analysis to search for compounds not included in the initial analysis is an attractive feature of TOP MS-based methods. Without additional injection of the samples, it is feasible to investigate the presence of other contaminants or metabolites. This has allowed the detection and identification of pharmaceutical metabolites in wastewater [51]. Obviously, this possibility is also available to other compounds, pesticides included, provided that they are compatible with the sample treatment and LC—MS analysis applied. A detailed comparison of the capabilities of LC—MS using QqQ, TOP, and QTOP for quantification, confirmation, and screening in the field of PRA is given in [45].
