13. Potentiality of Melastoma malabathricum as Phytoremediators of soil contaminated with sewage sludge
ABSTRACT: Heavy metal pollution of the soil environment has become a major source of concern and continues to pose serious health problems to both humans and ecological systems worldwide. Phytoremediation is a biological treatment whereby plants are used to remove pollutant from the environment. An experiment was conducted to evaluate the potential of Melast

14. TRANSPORT PARAMETERS OF POTASSIUM FROM DIFFERENT SOURCES IN SOIL COLUMNS
ABSTRACT This study aimed to determine some transport parameters of potassium in soil columns by miscible displacement of effluent from a Sewage Treatment Plant (STP). This effluent was collected at different stages of treatment, and potassium chloride solutions were prepared with the same K pulse concentration as the effluent. They were used to conduct a mi

15. Quantificação de alquilbenzeno linear sulfonato em estação de tratamento de efluentes e rios por cromatografia líquida de alta eficiência e extração em fase sólida
The procedures to implement a chromatographic method for the quantification of linear alkyl benzene sulfonate (LAS) in the influent, effluent and sludge of a wastewater treatment plant (WWTP), and in river water and sediment, are described and evaluated. The columns octylsilane (C8) and octadecylsilane (C18) for high performance liquid chromatography were ev

16. Solid-Liquid Extraction with Low Temperature Purification Coupled with Gas Chromatography and Mass Spectrometry for Determination of Polychlorinated Biphenyls in Sewage Sludge
Sewage sludge is the residue produced by the wastewater treatment plants, which can be used as soil conditioner in agriculture. However, the current legislation recommends monitoring chemical contaminants such as polychlorinated biphenyls (PCBs). In this study, solid-liquid extraction with low temperature purification (SLE-LTP) was optimized and validated fo

17. Energy generation in a Microbial Fuel Cell using anaerobic sludge from a wastewater treatment plant
ABSTRACT In microbial fuel cells (MFCs), the oxidation of organic compounds catalyzed by microorganisms (anode) generates electricity via electron transfer to an external circuit that acts as an electron acceptor (cathode). Microbial fuel cells differ in terms of the microorganisms employed and the nature of the oxidized organic compound. In this study, a co

18. Soil Chemistry after Irrigation with Treated Wastewater in Semiarid Climate
ABSTRACT Soil irrigation using treated wastewater in the Brazilian semiarid region is a promising practice as this area currently faces water scarcity and pollution of water resources by domestic sewage. The aim of this study was to evaluate the use of treated wastewater in drip irrigation and its effect on the chemistry of soil cultivated with squash (Cucur

19. 1H qNMR and Chemometric Analyses of Urban Wastewater
The industrial development, urbanization and agriculture play a major role in the degradation of the global environmental. Thus, the wastewater treatments need to be monitored continuously to ensure efficient operation. This manuscript presents an application of 1H nuclear magnetic resonance (NMR) associated with chemometric and quantitative analyses to stud

20. Morphology and 18S rDNA gene sequence of Spirostomum minus and Spirostomum teres (Ciliophora: Heterotrichea) from Rio de Janeiro, Brazil
Species of Spirostomum Ehrenberg, 1838 are widely used as model organisms in ecological studies of environmental impacts and symbioses between ciliates and human pathogenic bacteria. However, the taxonomy of this genus is confused by the superficiality of the morphological descriptions of its included species, and the use of only a few characters for their d

21. Nitrous oxide emissions from an intermittent aeration activated sludge system of an urban wastewater treatment plant
This study investigated the emission of N2O during the sequential aerated (60-min) and non-aerated (30-min) stages of an intermittent aeration cycle in an activated sludge wastewater treatment plant (WWTP). N2O emission occurred during both stages; however, emission was much higher during aeration. Air stripping is the major factor controlling transfer of N2

22. A evolução da qualidade das águas do rio Paraíba do Sul / The evolution of water quality in the Paraiba do Sul River
There are a number of uses that involve the water consumption that are direct consequences of the industrialization and urbanization intensive process, as well as population growth. The sewage treatment plants serve as environmental barriers increasing the multiple uses of water. This improvement in water quality reduces the risk of spreading diseases to the

24. Isolamento, seleção e cultivo de bactérias Produtoras de lipases para tratamento de Efluentes da indústria de alimentos / Isolation, selection and cultivation of bacteria Producing lipases for treating Effluents of the food industry
The present work was to isolate, select and cultivate microorganisms that produce lipases to apply the wastewater treatment industry of potato chips. For the isolation of microorganisms was used for industrial effluent and sewage treatment plant. The selection of the strain producing lipase was performed on solid medium containing tributyrin and in liquid me
