Concentrations of Cu, Fe, Mn, and Zn in tropical soils amended with sewage sludge and composted sewage sludge
(2013-04-01)
Sewage sludge may be used as an agricultural fertilizer, but the practice has been criticized because sludge may contain trace elements and pathogens. The aim of this study was to compare the effectiveness of total and ...

Avaliação de wetland construído de fluxo subsuperficial horizontal para o tratamento de esgoto sanitário
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de Química e BiologiaTecnologia em Processos AmbientaisUTFPR, 2015-02-13)
The problem of sanitation is much discussed now. Alternatives have been created for wastewater treatment, especially in locations distant from urban centers, where there is no collection and treatment of sewage. The rural ...
Sewage sludge coke estimation using thermal analysis
(Springer, 2011-11-01)
The imposition of more stringent legislation by CETESB in the State of So Paulo (Brazil) governing the disposal and utilization of sewage sludge, coupled with the growth in its generation has prompted a drive for alternative ...

Application of chemometric methods in the evaluation of chemical and spectroscopic data on organic matter from Oxisols in sewage sludge applications
(Elsevier B.V., 2010-02-15)
Chemometric methods can contribute to soil research by permitting the extraction of more information from the data. The aim of this work was to use Principal Component Analysis to evaluate data obtained through chemical ...
Evaluation of metal removal efficiency and its influence in the physicochemical parameters at two sewage treatment plants
(2018-05-01)
In sewage treatment plants, physicochemical parameters are highly controlled since treated sewage can be returned to water bodies or reused. In addition, pollutants such as heavy metals also deserve attention due to their ...
Rapid determination of 12 antibiotics and caffeine in sewage and bioreactor effluent by online column-switching liquid chromatography/tandem mass spectrometry
(2015-10-07)
This study presents a column-switching solid-phase extraction online-coupled to a liquid chromatography/tandem mass spectrometry (SPE-LC-MS/MS) method for simultaneous analysis of 12 antibiotics (7 sulfonamides and 5 ...
