1. THE "CHEMICAL OXYGEN DEMAND / TOTAL VOLATILE ACIDS" RATIO AS AN ANAEROBIC TREATABILITY INDICATOR FOR LANDFILL LEACHATES
Abstract In some operational circumstances a fast evaluation of landfill leachate anaerobic treatability is necessary, and neither Biochemical Methane Potential nor BOD/COD ratio are fast enough. Looking for a fast indicator, this work evaluated the anaerobic treatability of landfill leachate from São Carlos-SP (Brazil) in a pilot scale Anaerobic Sequence B

2. 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

3. A novel hybrid optimization algorithm for diferential-algebraic control problems
Dynamic optimization problems can be numerically solved by direct, indirect and Hamilton-Jacobi-Bellman methods. In this paper, the differential-algebraic approach is incorporated into a hybrid method, extending the concepts of structural and differential indexes, consistent initialization analysis, index reduction and dynamic degrees of freedom to the optim

4. Estudo da remoção de nitrogênio via nitrito e via nitrato em sistemas de lodo ativado alimentados por despejo com elevada concentração de fenol. / Study of nitrogen removal via nitrite and via nitrate in activated sludge systems fed by wastewater with high phenol concentration.
Wastewaters containing high phenol and ammonium concentrations present a great pollutant potential to the environment. An example of this kind of effluent is the discharge of coke-plants, which presents, quantitatively, the phenols as the main organic compound. Inorganic compounds are also present in these wastewaters and are mainly cyanide, thiocyanate, sul

5. Estudo da remoção biológica de nitrogênio via nitrito utilizando fenol como fonte de carbono operando um reator em bateladas seqüenciais (SBR) em escala piloto. / Study of nitrogen biological removal via nitrite using phenol as carbon source operating a pilot scale sequence batch reactor (SBR).
A presente pesquisa propôs avaliar a remoção biológica do nitrogênio pela via simplificada (nitritação) utilizando fenol como fonte de carbono na etapa anóxica (desnitritação) em um sistema de lodos ativados com biomassa em suspensão. Para tanto operou-se um reator piloto (volume útil de 20 litros) em bateladas seqüenciais alimentado com 5 (cinc

6. Correspondence between Community Structure and Function during Succession in Phenol- and Phenol-plus-Trichloroethene-Fed Sequencing Batch Reactors
The effects of more than 2 years of trichloroethene (TCE) application on community succession and function were studied in two aerobic sequencing batch reactors. One reactor was fed phenol, and the second reactor was fed both phenol and TCE in sequence twice per day. After initiation of TCE loading in the second reactor, the TCE transformation rates initiall

7. Community Structure and Activity Dynamics of Nitrifying Bacteria in a Phosphate-Removing Biofilm
The microbial community structure and activity dynamics of a phosphate-removing biofilm from a sequencing batch biofilm reactor were investigated with special focus on the nitrifying community. O2, NO2−, and NO3− profiles in the biofilm were measured with microsensors at various times during the nonaerated-aerated reactor cycle. In the aeration period, n

8. Use of Stable-Isotope Probing, Full-Cycle rRNA Analysis, and Fluorescence In Situ Hybridization-Microautoradiography To Study a Methanol-Fed Denitrifying Microbial Community
A denitrifying microbial consortium was enriched in an anoxically operated, methanol-fed sequencing batch reactor (SBR) fed with a mineral salts medium containing methanol as the sole carbon source and nitrate as the electron acceptor. The SBR was inoculated with sludge from a biological nutrient removal activated sludge plant exhibiting good denitrification
