1. Aerobic biofilms for nitrogen removal in flow cells, submitted to different superficial velocities and loading rates / Biofilmes aeróbios para remoção de nitrogênio em células de fluxo, submetidos a diferentes velocidades superficiais e taxas de carregamento
The post-treatment of anaerobic reactor effluents, such as the Upflow Anaerobic Sludge Blanket (UASB), in most applications, is necessary, since this kind of biological treatment promotes BOD removal ranging from 60 to 75% and it has low efficiency in nitrogen and phosphorous removal. Nitrogen removal is usually carried out in a conventional way through nitr

2. New configuration of submerged aerated biofilter used in the effluent UASB reactor post-treatment / Nova configuração de biofiltro aerado submerso utilizado no pós-tratamento do efluente de reator UASB
O principal objetivo desse trabalho foi desenvolver uma nova configuração de biofiltro aerado submerso utilizado no pós-tratamento do efluente de reator UASB, capaz de realizar nitrificação e desnitrificação em um único sistema. Em busca de bases operacionais dessa nova configuração, a pesquisa foi inicialmente conduzida com três reatores seqüenc

3. Biofiltro aerado submerso aplicado ao pós-tratamento de efluente de reator UASB, sob condições hidráulicas desfavoráveis: estudo em escala real / Submerged aerated biofilter used for post-treatment of the effluent of an UASB reactor, under unfavorable hydraulic conditions: full-scale study
Esta pesquisa avaliou a eficiência do biofiltro aerado submerso empregado no pós-tratamento do efluente do reator anaeróbio de manta de lodo (UASB), em escala real, localizado na ETE Água Vermelha em São Carlos, SP, sob condições hidráulicas desfavoráveis. Estudou-se a remoção de matéria orgânica e de sólidos, a possibilidade de remoção de ni

4. Post-Treatment for effluents of anaerobic reactors treating domestic effluent by natural and unnatural coagulants / Pós-Tratamento de Efluentes Provenientes de Reatores Anaeróbios Tratando Esgotos Sanitários por Coagulantes Naturais e Não-Naturais
The current investigation aimed to study post-treatments for effluents of anaerobic sludge blanket reactors by using both natural (Moringa oleifera, Lam) and unnatural coagulants. For that, many jar-tests were conducted either using sewage or effluent of a lab-scale UASB (upflow anaerobic sludge blanket) reactor. Many dosages of natural (Moringa oleifera) an

5. Coagulation/precipitation of effluents from anaerobic expanded bed reactor and activated sludge system preceded by UASB reactor, with particle removal by sedimentation or flotation / Coagulação/precipitação de efluentes de reator anaeróbio de leito expandido e de sistema de lodo ativado precedido de reator UASB, com remoção de partículas por sedimentação ou flotação
The anaerobic reactors of modern conception (e.g., UASB and RALEx) remove from 65 to 75% of sanitary wastewater organic matter with relatively low construction, operation, and maintenance costs, in comparison with conventional aerobic processes. Nevertheless, that reactors are usually little efficient in nutrient removal and their effluents may present relat

6. Avaliação da microfiltração tangencial como alternativa de tratamento avançado de efluente gerado em sistema de tratamento de esgoto sanitário constituído de reator UASB (Upflow Anaerobic Sludge Blanket) seguido de tanque de aeração / The evaluation of crossflow microfiltration as an alternative for advanced treatment of effluent generated in a system of sewage treatment composed by a UASB (Upflow Anaerobic Sludge Blanket) reactor followed by an aeration tank
The proposal of this research was to evaluate the crossflow microfiltration as an alternative for an advanced treatment of effluent generated in a system of sewage treatment composed by a UASB (Upflow Anaerobic Sludge Blanket) reactor followed by an aeration tank. This work aimed to evaluate the membranes physical cleaning methods (backwashing with compresse

8. Lamella design (high rate) and conventional flotation units applied to the post-treatment of the effluent from a system made up anaerobic reactor followed by aerobic reactor treating domestic sewage / Emprego da flotação lamelar de alta taxa e convencional como pós-tratamento do efluente de sistema constituído de reator anaeróbio seguido de reator aeróbio tratando esgoto sanitário
The aim of this research was the study of the lamella design (high rate) and conventional dissolved air flotation (DAF) process potentiality of application as the final part of a domestic sewage sequential treatment system made up anaerobic reactors (UASB) followed by aeration tank. The work, developed at the Jardim das Flores WWTP of Rio Claro city, was sep

9. Tratamento anaerÃbico de efluentes gerados em matadouros de bovinos / Anaerobic Treatment of Effluents from Slaughterhouses
Generation of wastes in the agroindustrial activities is very significant, especially in the case of the slaughterhouses. In Pernambuco, the slaughterhouses are considered as an important contributor for the growing pollution of the receiving water bodies. Despite the available technology for effluents treatment, they are seldom used. The present work evalua

10. Pós-tratamento de efluente de reator UASB em sistema de lodos ativados visando a remoção biológica do nitrogênio associada à remoção físico-química do fósforo. / Association of biological removal of nitrogen and physical-chemical of phosphorus by means of activated sludge post-treatment of UASB reactor effluent.
In this research work a pilot-scale, activated sludge plant was operated to treat the treated effluent of an anaerobic treatment system, in order to remove nitrogen and phosphorus. The pilot unit was composed of anoxic reactor, aerobic reactor and secondary settler. The experiments were carried out while keeping both the affluent and return sludge flow rates
