1. SEWAGE PERFORMANCE OF A NEW TYPE OF FLAP FILTER
ABSTRACT The drainage performance of a mesh filter determines the water consumption degree of the filter and the efficiency of the next work cycle. Through analysis, we found that the influent flow rate and the sediment content of the influent were important influencing factors. This experiment focused on the drainage time, pressure difference, and cleanline

2. Consortium of Microalgae for Tannery Effluent Treatment
Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather)

3. Obtainment, quantification and use of lactulose as a functional food – a review
Abstract Whey (milk serum) is produced by the dairy industry during the manufacture of cheese. In addition to being a valuable source of functional and nutritional proteins, whey also presents almost all the lactose from the original whole milk. However, many industries still consider the whey as an effluent, which can cause serious environmental problems wh

4. 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

5. Microalgae population dynamics in photobioreactors with secondary sewage effluent as culture medium
Nitrogen and phosphorus present in sewage can be used for microalgae growth, possibiliting cost reduction in the production of microalgae at the same time that it decreases the eutrophication potential of the effluent. This research aimed at monitoring the native community of microalgae and coliform bacteria in a secondary effluent from anaerobic municipal s

6. Adsorção de o-xileno em argila fluidgel organofílica em fase gasosa / Adsorption of o-xylene onto organoclay fluidgel in gas phase
The industrial growth allied to use of petroleum products generate numerous volatile organic compounds (VOC) that are continuously emitted to the atmosphere, degrading air quality and causing serious problems to human health and environment. Among the VOC, the so-called BTEX (benzene, toluene, ethyl benzene, and xylene), are the most important in terms of to

7. Desempenho de tanques vegetados em um ecossistema engenheirado para tratamento descentralizado de esgotos domiciliares na Ilha Grande, RJ / Performance of vegetated tanks in an engineered ecosystem for decentralized treatment of sewage in Grande Island, RJ
The lack of appropriate infrastructure for sewage collection and treatment affects several communities living under unhealthy conditions in coastal areas and in insular systems in Rio de Janeiro State. The objective of this study was to assess the performance of an engineering ecosystem for the descentralized treatment of domestic wastewater located at the C

8. Mecanismos de remoção de compostos orgânicos no sistema de lodos ativados de uma fábrica de polpa Kraft branqueada de eucalipto / Removal mechanisms of organic compounds in a eucalyptus bleached kraft pulp mill activated sludge plant
The composition and adsorptive capacity of extracellular polymeric substances (EPS) in a eucalyptus bleached kraft pulp mill activated sludge plant were investigated. Samples of primary and secondary effluents and activated sludge were collected over five months. Effluents were characterized by quantifying dissolved organic carbon (DOC), chemical (COD) and b

9. Comportamento hidrodinâmico e cinético dos reatores anaeróbios compartimentado (RAC) e manta de lodo (UASB) operados em série / The hydrodynamic and kinetic bahavior of the anaerobic baffled reactor (ABR) and upflow anaerobic Sludge blanket (UASB) operated in serie
The aim of this research was to determine the hidrodymanic and kinetics behavior of a pilot system plant, treating swine liquid effluent, installed in the Zootechnical Department of the Federal University of Lavras. The pilot system was composed by several units working in series, such as sand retention box (SRB), static sieve (SS), acidification and equaliz

10. Tratamento com lodo aeróbio granular de efluente de fábrica de papel / Aerobic granular sludge treatment of paper mill effluents
The activated sludge process is widely used for the treatment of industrial effluents, achieving high rates of organic matter removal. Nevertheless, the separation of biological sludge in secondary clarifiers can be a serious problem of this process due to the poor floc formation, causing solids losses and, consequently, deterioration of treated effluent qua

11. Reúso de efluente de esgoto sanitário anaeróbio e nitrificado em irrigação de roseiras / Reuse of anaerobic and nitrified wastewater effluents for irrigation of roses
Wastewater secondary treatment plants effluent may contain, yet, nutrients in amounts harmful to the environment. These effluents discharging can cause eutrophication in receiving waters, making it unsuitable for intended uses, such as provision for human consumption, leisure activities, etc. Besides the problem of eutrophication, there is the difficulty to

12. Emissão de óxido nitroso de estação de tratamento de esgoto de lodos ativados por aeração prolongada - estudo preliminar
Nitrous oxide emissions from an activated sludge plant which serves a research institute in Rio de Janeiro city were estimated from six unit processes (grit tank, sand trap, aeration tank, secondary settling tank, sludge recirculation line and aerobic digester sludge tank) and also from the plant effluent. Total estimated annual flux was 3.2 x 10(4) g N2O yr
