13. Craqueamento termo-catalítico da mistura óleo de fritura usado-lodo de estamparia têxtil para a produção de óleo com baixo índice de acidez
In this work, cracking experiments were performed to carry out the thermal conversion of the mixture of used frying oil and textile stamping sludge in continuous reactor. The textile stamping sludge was used to catalyze the reaction of thermal cracking. The physical and chemical properties of the oil produced were analyzed. Among the results of this analysis

14. Tratamento do efluente do biodiesel utilizando a eletrocoagulação/flotação: investigação dos parâmetros operacionais
Electrocoagulation/flotation process was applied to treat biodiesel wastewater using aluminium electrodes. Firstly, a literature survey was conducted to choose the process variables and then, operational parameters including initial pH, electrode distance and reaction time were tested. Experimental results showed the best parameter that can be used in a fact

15. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

16. 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

17. ESTUDO DAS PROPRIEDADES ELÉTRICAS DE COMPÓSITOS CARBONO-ARGILA OBTIDOS A PARTIR DA BORRA DE PETRÓLEO PELO MÉTODO DE QUATRO PONTAS / STUDY OF ELECTRICAL PROPERTIES OF CARBON-CLAY COMPOSITES OBTAINED FROM THE METHOD OIL SLUDGE FOUR TIPS
A indústria petrolífera produz quantidades significativas de resíduos em vários dos seus processos, desde a perfuração de poços até a distribuição de seus derivados. Nesse ambiente industrial surge a chamada água produzida, que ao ficar em tanques de flotação, gera um resíduo chamado de borra de petróleo. A partir de uma observação prelimina

18. ESTUDO DAS PROPRIEDADES ELÉTRICAS DE COMPÓSITOS CARBONO-ARGILA OBTIDOS A PARTIR DA BORRA DE PETRÓLEO PELO MÉTODO DE QUATRO PONTAS / STUDY OF ELECTRICAL PROPERTIES OF CARBON-CLAY COMPOSITES OBTAINED FROM THE METHOD OIL SLUDGE FOUR TIPS
The petroleum industry produces significant amounts of residues in several of its processes, from the perforation of wells, production, storage, transport and refining, to the distribution of its derivatives. The wastewater generated in the oil extraction step is known as produced water and, when stored in flotation tanks, if generates a residue called oily

19. GestÃo e caracterizaÃÃo dos resÃduos sÃlidos da Lubnor/PETROBRAS: estudo de caso / Management and characterization os solid waste Lubnor/PETROBRAS: a case study
The situation of solid waste in Brazil is worrying, especially with regard to final disposal, as the increase in the wasteâs generation was not followed by a growth of infrastructure. The environmental issue, with the onset and worsening of environmental problems become more important to humans. Most of these problems is due to industrial waste origin, as m

20. 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

21. Caracterização do conteúdo de fossas e tanques sépticos na cidade de Natal
Only 32% of the population of Natal is attended by sewage, while the remaining population use pits and septic tanks. The characterization of the contents of septic tanks and pits contributes to the performance of such system and may guide the decision on treatment of these contents. The main of this research is to characterize the contents of interior reside

22. Extração do óleo e caracterização dos resíduos da borra de petróleo para fins de reuso
The petroleum industry, in consequence of an intense activity of exploration and production, is responsible by great part of the generation of residues, which are considered toxic and pollutants to the environment. Among these, the oil sludge is found produced during the production, transportation and refine phases. This work had the purpose to develop a pro

23. THE EFFECT OF DIFFERENT METALLIC ELECTRODES ON THE ELECTROCOAGULATION OF OILY WASTEWATER / O EFEITO DE DIFERENTES ELETRODOS METÁLICOS NA ELETROCOAGULAÇÃO DE EFLUENTES OLEOSOS
In the present work, electrocoagulation process (EC) with aluminum and iron as materials for anode and stainless steel as cathode, under different operational parameters, such as: initial concentration of oil, distance between electrodes, area-volume relation (SA/V) and current density, were examined in a systematic manner. Chemical oxygen demand (COD) and t

24. Treatment of industry wastewater from a plastic containers (containing originally lubricant oil) recycling industry : biological and physical-chemical process / Tratamento de efluentes de uma industria de reciclagem de embalagens plasticas de oleos lubrificantes : processo biologico e fisico-quimico
In the present work, the treatment of the wastewater originated in a plastic container (containing originally lubricant oil) recycling industry was investigated. The purpose of this work was to study the individual efficiency to treat the industrial effluent, mixture of the plastic container washing process wastewater and sanitary wastewater, by activated sl
