1. 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

2. 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

3. Dinâmica de Sedimentação de Lodo em Lagoas de Estabilização / Sludge Sedimentation Dynamics in Stabilization Ponds
Stabilization ponds are an effective sewage treatment alternative for the climatic conditions prevailing in Brazil. In the present work, a primary facultative pond was studied, in the city of Natal, Rio Grande do Norte, Northeast Brazil. The aim of this study was to evaluate the sedimentation dynamics in the facultative pond. The pond was divided in three se

4. Definição de alternativas de pré-tratamento de efluentes não domésticos em sistemas públicos de esgotos, utilizando o teste de avaliação da toxicidade refratária. / Definition of petreatment alternatives to non domestic effluent in public owned treatment works (POTWs), using the refractory toxicity assessment test (RTA).
Typically, the cause of effluent aquatic toxicity is unknown. Due to this and the complex makeup and varying toxicants in individual waste streams, a toxicity reduction program must usually begin at the discharge and proceed upstream to find the source. The key toxicant(s) and the actual toxic mechanism are normally not apparent from traditional characteriza

5. Inactivation of poliovirus in digested sludge.
The effect of anaerobically digested sludge on poliovirus during incubation at temperatures between 28 and 4 C was studied. Although virus was fully recoverable from sludge, its infectivity decreased in proportion to the time and temperature of incubation. The rate ranged from greater than 1 log per day at 28 C to about 1 log every 5 days at 4 C. The mechani
