13. 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

14. Caracterização de resíduos sólidos de estação de tratamento de esgoto da indústria de batatas e avaliação como adição para a produção de compósitos cimentícios / Caracterização de resíduos sólidos de estação de tratamento de esgoto da indústria de batatas e avaliação como adição para a produção de compósitos cimentícios
O grande volume de resíduos sólidos industriais gerados pela indústria de batatas pré-fritas e o alto custo do seu manejo estimulam pesquisas em busca de soluções mais adequadas para a sua destinação final. Uma alternativa que se destaca neste contexto é o aproveitamento destes resíduos na construção civil. Os produtos à base de cimento Portland

15. Emissão de metano nas lagoas de decantação da Estação de tratamento de esgotos de Jundiaí / Methane emission from decantation lagoons in Jundiaí wastewater treatment plant
In the present work was estimated the contribution of methane emission to the global atmosphere. In this study were realized two campaigns of collections in the settling ponds n.°03 (2008) and n.°04 (2010) with sampling operation being carried out in points coming into and out of the lagoons. A gas collector has been utilized as the UASB inner gas keeper a

16. Lamella sedimentation: alternative for treatment of overflow sewage - study in ETE Martim de Sá (Caraguatatuba/SP). / Decantação acelerada: alternativa para o tratamento de vazão excedente de esgoto - estudo na ETE Martim de Sá (Caraguatatuba/SP).
This study was motivated by the need to treat high wastewater influent exceeding in sewage treatment plants, which occurs on days of heavy rain. The central hypothesis of this study is that the physical-chemical process to treat dilute sewage overflow, it can be advantageous with respect to increased capacity and expansion of biological systems. The research

17. Characterization and treatment of sludge originated from septic tanks / Caracterização e pré-tratamento de lodo de fossas e de tanques sépticos
Septic tanks are small structures used for partial treatment of wastewater produced from urban and rural areas. It utilization is justify mainly by simplicity of construction and for being a technology that requires low operational dedication. Although it is a technology vastly used in Brazil, there is not much information about the characteristics of the wa

18. Tratamento físico-químico de lixiviado de aterro sanitário pré-tratado por processo biológico aeróbio. / Physico-chemical treatment of landfill leachate from pre-treated by aerobic biological process.
Landfill leachates present high ammonia and organic matter concentrations, besides other pollutants, which do not allow its discharge to the environment without a previous treatment. Older landfill leachates, with more stabilized organic matter, present great pollutant potential, mainly due to the presence of recalcitrant substances that not often are remove

19. Avaliação do potencial genotóxico e cancerígeno do lodo de estação de tratamento de esgoto (LETE) em sistemas experimentais in vivo / In vivo evaluation of the carcinogenic potential of sewage sludge from a urban wastewater treatment plant in experimental systems
A rápida oxidação da matéria orgânica dos solos tropicais é mais uma evidência da grande vantagem do uso de biossólidos como condicionadores, capazes de melhorar as características físicas, químicas e biológicas do solo com grandes reflexos na produtividade agrícola. Portanto, o presente projeto objetivou averiguar o potencial genotóxico e canc

21. Molecular detection of human astrovirus in an urban sewage treatment plant in Rio de Janeiro, Brazil
The objective of this study was to evaluate the prevalence and dissemination of human astroviruses (HAstV) in the environment by analyzing urban sewage samples from a wastewater treatment plant in the city of Rio de Janeiro, Brazil. A one-year study was performed with a total of 48 raw and treated sewage composite samples, which were collected biweekly from

22. Use of geographic information system in watershed management of water treatment plants sludge / Uso de sistema de informações geograficas na gestão do lodo das estações de tratamento de agua de uma bacia hidrografica
Present work investigates the use of geographic information system (GIS) - nowadays a necessary technique for spatial data analysis, broadly used as decision-making aid in many fields - as a tool for watershed management for disposal or beneficial use of water treatment plants (WTP) sludge. Most of times, residuals management is based in conventional data, c

23. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

24. Zn, Ni, Cu, Fe and S in sewage sludge: chemical behaviour, adsorption and treatment proposal / Zn, Ni, Cr, Cu, Fe e S em Iodo de esgoto: comportamento químico, adsorção e proposta de tratamento
The increase of the wastewater treated volume in Brazil has demanded alternatives to the sewage sludge final disposal. At first, agricultural use is one of the viable recommendations since sludge is rich in organic matter, macro and micronutrients necessary to the fertility of the soil. However, it is necessary to consider the environmental impact of some of
