1. Degradação do fungicida tiofanato metílico pelo processo foto-Fenton em reatores anular e solar
Os efluentes das indústrias de agrotóxicos apresentam grande dificuldade quanto à sua descontaminação no meio ambiente e, além disso, são caracterizados por possuírem alta carga orgânica e toxicidade. O grupo de pesquisa do Centro de Engenharia de Sistemas Químicos (CESQ) do Departamento de Engenharia Química da Escola Politécnica da Universidade

3. Experimental study and mathematical modeling of hybrid solar reactor for phenol degradationby photo-Fenton process. / Estudo experimental e modelagem matemática de reator solar híbrido para degradação de fenol em solução aquosa pelo processo foto-Fenton.
Wastewaters containing hazardous, or recalcitrant organic substances are generated in a wide variety of industrial processes. The inadequate management of these effluents can cause contamination of underground and surface water. Their treatment by conventional processes may not be technically efficient, and usually prevents effluents from being discarded or

4. Pos-tratamento de esgoto por fotocatalise heterogenea solar antes e apos filtração lenta / Post-treatment of sewage by solar heterogeneous photocatalysis before and after slow filtration
Currently, techniques for reuse of water using renewable energy sources and building materials at low cost are used in small scale to serve needy populations in sanitation in order to minimize transmission of diseases and water contamination from chemical compounds harmful to human health. The advanced oxidative process (AOP) is a technology developed to min

5. Use of solar energy in the treatment of water contaminated with phenol by photochemical processes
The solar driven photo-Fenton process for treating water containing phenol as a contaminant has been evaluated by means of pilot-scale experiments with a parabolic trough solar reactor (PTR). The effects of Fe(II) (0.04-1.0 mmol L-1), H2O2 (7-270 mmol L-1), initial phenol concentration (100 and 500 mg C L-1), solar radiation, and operation mode (batch and fe

6. Estudo de reatores eletroquímicos para remoção de Cu2+ , Zn2+, Fenol e BTEX em água produzida
The production of water has become one of the most important wastes in the petroleum industry, specifically in the up stream segment. The treatment of this kind of effluents is complex and normally requires high costs. In this context, the electrochemical treatment emerges as an alternative methodology for treating the wastewaters. It employs electrochemical

7. Wave packet description of neutrino oscillation in a progenitor star supernova environment
In this work we briefly review the wave packet approach of two generation neutrino oscillation, aiming its description in a progenitor star supernova environment. We begin calculating the wave packet size in many situations: solar and supernova plasma medium, considering nuclear interactions, as well as accelerators and reactors. This quantity is important t

8. Ti O IND.2 heterogeneous photocatalysis in secondary wastewater treatment / Fotocatálise heterogênea com Ti O IND.2 aplicada ao tratamento de esgoto sanitário secundário
The heterogeneous photocatalysis with Ti O IND.2 and solar radiation in secondary wastewater treatment to remove organic matter and microorganisms was investigated. A glass plate (approximate 0.48 M POT.2 ) with immobilized titanium dioxide (10 g/ M POT.2 ) was operated in different flow rates (15; 22.5 and 30 L/h) and angles in relation to horizontal (2, 12

9. Influence of the solar and density perturbations on the neutrino parameters
There are reasons to believe that the solar matter density fluctuates around an equilibrium profile. One of these reasons is a resonance between the Alfvén waves and the g-modes inside the Sun that creates spikes in the density profile. The neutrinos are created in the solar core and passing through these spikes feel them as a noisy perturbation, whose corr
