Anaerobic digestion is a highly efficient wastewater treatment method that could potentially be used to treat sugarcane vinasse. This study examined the anaerobic biodigestion of sugarcane vinasse in mesophilic conditions (30 - 45°C) by varying the inoculum concentration (0.5 to 5.5%) and pH (6 - 8). Changes of Chemical Oxygen Demand (COD), total solids content, and yield and composition of biogas after the biodigestion of the vinasse were assessed. The vinasse was efficiently digested under mesophilic anaerobic conditions over a 23-day Hydraulic Retention Time (HRT) and a 5-day acidogenic phase with a consequent reduction of COD (54 - 83%) and total solids (52 - 87%). Statistical analyses at a confidence level of 95% suggested that temperature, pH and inoculum concentration did not influence on the anaerobic biodigestion of the vinasse. The optimal operating parameters were found to be temperatures of 30 - 35°C, inoculum concentration of 0.5% and pH of 6 - 7. The results emphasize the promising use of the treated sugarcane vinasse as a biofertilizer for agriculture, indicating that the anaerobic digestion process is an excellent alternative for Brazilian ethanol industries.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"763-777"},"PeriodicalIF":0.0,"publicationDate":"2016-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4136/AMBI-AGUA.1897","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70666036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

O objetivo foi sumarizar as principais caracteristicas metodologicas e os principais achados descritos em estudos sobre monitoramento da concentracao de fluoreto em agua de abastecimento publico, que foram publicados em revistas cientificas especializadas entre 2008 e 2012, examinando suas implicacoes para a vigilância em saude publica. Uma revisao sistematica foi realizada buscando artigos nas bases de dados Embase, Lilacs e PubMed. Trinta e seis artigos foram incluidos: 28 das Americas, cinco da Asia, dois da Africa e um da Europa. A variabilidade dos estudos quanto ao desenho e aos procedimentos metodologicos foi elevada. Embora tenha sido oferecida informacao sobre a distribuicao espaco-temporal das amostras, poucos trabalhos descreveram a populacao coberta pela fonte de abastecimento investigada. Quase metade dos estudos foi do tipo transversal e nenhuma medida de dispersao ou de variacao foi associada ao valor medio. Predominou o uso do metodo eletrometrico e a classificacao dicotomica do tipo adequado/inadequado e/ou acima/abaixo para avaliar os resultados. Menos da metade dos estudos esteve articulada a vigilância como acao do Estado, e um numero ainda menor levantou hipoteses sobre possiveis fatores associados aos resultados encontrados. Ha um espaco importante a ser diminuido entre os resultados dessas iniciativas e o uso das informacoes pelas autoridades de saude publica e tambem para melhorar os procedimentos metodologicos em futuros estudos. A interacao entre os pesquisadores e os orgaos de controle da qualidade da agua deveria ser incrementada.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"972-988"},"PeriodicalIF":0.0,"publicationDate":"2016-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70666132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The air pollution control system train consisted of a first stage, including a chemical scrubber operating with an alkaline solution containing caustic soda, followed by a two-stage biotrickling filter (BTF) filled with Mytilus edulis shells. This study evaluated the performance of the dual-stage BTF in removing hydrogen sulphide (H2S), sulphur dioxide (SO2) and dimethyl sulphide (DMS) from the phosphoric acid reactor's exhaust air current. Concentrations of H2S, SO2 and DMS at the inlet of the two-stage BTF were 10-30 ppm, < 1-20 ppm and 16-30 ppm, respectively. All of the respective concentrations at the outlet of the biological step were < 1 ppm, except for the H2S in the outlet during the first day of operation (10 ppm). Removal efficiencies were generally higher than 95% for all compounds, and remained high even with an increase of the off-gas flow rate. Mass-removal capacity was at least 2.0 g m-3 h-1, 0.5 g m-3 h-1 and 6.2 g m-3 h-1, for H2S, SO2 and DMS, respectively. The removal efficiencies of the process were satisfactory, especially considering the already low inlet concentrations, due to the high quality of the raw phosphate used.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"499-507"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4136/AMBI-AGUA.1848","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70665765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, Advanced Oxidation Processes (AOPs) - technologies that principally use the hydroxyl radical (HO●) for oxidation - have emerged as promising alternatives in treating urban and industrial wastewaters. This study reviewed the literature on POAs and presented data regarding the efficiency of these processes in pollutant degradation, comparing the theoretical reasoning and its industrial applications. The fundamentals and major applications of AOPs (chemical, photochemical, electrochemical, sonochemical and ozone-based processes), as well as their advantages and disadvantages, are described in this review. AOPs have been considered an effective alternative from a technical, economic and environmental viewpoint for the degradation of pollutants in effluents and industrial wastewater, despite having limitations such as high cost of available energy sources, development of new low-cost catalytic materials and construction of full-scale reactors. It is greatly important to the industrial application of AOPs to optimize the effectiveness of these factors.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"387-401"},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4136/AMBI-AGUA.1862","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70665919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study also verified the decrease in the activity of these microorganisms by heterotrophic bacterial count before and after treatment with three different sanitizers. The presence of coliform (NMP > 1600) and Pseudomonas aeruginosa was observed in both the irrigation water and in the irrigated food, and the coefficient of variation (R2) revealed a strong correlation between the rates of contamination of the water and food. All of the sanitizers evaluated reduced the bacterial load of the food, especially sanitization with vinegar at 200 ppm, which, in addition to greatly reducing food contamination, is also considered a low-cost and toxicologically safe product, and therefore may be indicated for this purpose. Thus, the use of poor quality water in the irrigation of vegetables may directly contribute to food contamination, with serious implications for the health of consumers.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"428-438"},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70666066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sin duda la generacion de modelos espaciales que integran esos elementos y factores, ayudan a predecir zonas potenciales de incendios con mas exactitud. El Area de Proteccion de Flora y Fauna La Primavera (APFFLP) constituye el principal regulador climatico de la zona metropolitana de Guadalajara, y presenta frecuentemente incendios forestales, por lo que representa un reto para la ciencia y la tecnologia utilizarla como modelo para desarrollar metodologias que ayuden a predecir incendios forestales. El presente estudio se enfoca a la construccion de un modelo espacial que ayuda a determinar zonas potenciales de incendios en dicha area. El modelo integra variables meteorologicas, de paisaje, de combustibles, antropogenicas y/o de causalidad; y las ocurrencias historicas de los incendios comprendidos durante el periodo 1998-2012. Segun el modelo, las variables que determinan las zonas con mayor potencial de incendios son: la pendiente (paisaje), la humedad relativa (meteorologica), el tipo de vegetacion (causalidad) y el uso del suelo (antropogenicas). El modelo predice una zona extensa con alto potencial de incendiarse, ubicada en la parte central y noroeste del poligono del APFFLP; asimismo, existen zonas potenciales pequenas y aisladas ubicadas en el oriente del poligono. La informacion generada en este estudio podria ayudar a la generacion de mapas de riesgo locales y con ello, optimizar las acciones de manejo del fuego y restauracion del Bosque La Primavera.","PeriodicalId":38374,"journal":{"name":"Revista Ambiente e Agua","volume":"11 1","pages":"35-49"},"PeriodicalIF":0.0,"publicationDate":"2016-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4136/AMBI-AGUA.1536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70664737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
