2. Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
Abstract: The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment due to their low-cost and minimal need for operational requirements. Microorganisms present in wastewater treatment plant (WWTP)

3. 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

4. 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

5. 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

6. Bacterial ecology of abattoir wastewater treated by an anaerobic digestor
Abstract Wastewater from an anaerobic treatment plant at a slaughterhouse was analysed to determine the bacterial biodiversity present. Molecular analysis of the anaerobic sludge obtained from the treatment plant showed significant diversity, as 27 different phyla were identified. Firmicutes, Proteobacteria, Bacteroidetes, Thermotogae, Euryarchaeota (methano

7. Sequencing batch reactor operation for treating wastewater with aerobic granular sludge
In this work, the performance of a sequencing batch reactor (SBR) on aerobic granular sludge was studied for urban wastewater treatment. The system was inoculated with aerobic activated sludge collected from a wastewater treatment plant and, after 30 days of operation, the first granules observed had an average diameter of 0.1 mm. The biomass concentration r

8. The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis

9. 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

10. Avaliação da eficiência de ETE compacta e sua influência no Ribeirão Capivari em Ingleses, Florianópolis/SC
O alcance de atendimento à população pelos sistemas de tratamento de esgoto coletivo é precário. Uma alternativa que vem sendo adotada em vários empreendimentos são as estações de tratamento de esgoto compactas. Tal alternativa merece este estudo, que foi realizado na região norte de Florianópolis-SC, e teve como objetivo avaliar o comportamento d

11. Ex-situ bioremediation of Brazilian soil contaminated with plasticizers process wastes
The aim of this research was to evaluate the bioremediation of a soil contaminated with wastes from a plasticizers industry, located in São Paulo, Brazil. A 100-kg soil sample containing alcohols, adipates and phthalates was treated in an aerobic slurry-phase reactor using indigenous and acclimated microorganisms from the sludge of a wastewater treatment pl

12. Disposição de lodo adensado de ETA em ETE com tratamento primário quimicamente assistido / Thickened water treatment sludge disposal in a wastewater treatment presenting a chemically enhanced primary treatment
Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical p
