1. Avaliação do tratamento de lixiviado de aterro sanitário através de processo oxidativo avançado conjugado com sistema de separação por membranas
The landfill leachate is characterized by high recalcitrant organic matter concentration, ammonia and toxic compounds. This effluent can be an environmental problem due to its high pollutant potential when it is released without treatment. Studies reported in the literature showed that biological processes are not sufficient in meeting the discharge standard

3. 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

4. CONCEPÇÃO, CONSTRUÇÃO E AVALIAÇÃO DE FOTORREATORES CATALISADOS NA DEGRADAÇÃO DE CARGA POLUENTE E AMOXICILINA EM EFLUENTE HOSPITALAR
The focus of this study was the application of advanced oxidation photoprocesses, heterogeneous photocatalysis and photo-Fenton, in the degradation of pollutant load and amoxicillin in wastewater from the University Hospital of Santa Maria (HUSM), evaluating the photoreactors performance in the degradation efficiency. In the hospital wastewater there is a wi

5. RemediaÃÃo de solos contaminados por derivados de petrÃleo utilizando processo foto-fenton
In the manipulation of petroleum derivatives may occur the contamination of soil, because of leaks, spills and other accidents during the exploration, refining, transport and storage. Those accidents have been increasing in the last years due to the growing demand of energy of the country. Many of these pollutants are highly impactants for man and environmen

6. Fungos degradadores de compostos organicos recalcitrantes sob condições microaerobia e anaerobia
The industrial activities of modern society produce great amounts of toxic compounds, which persist in rivers, soils and oceans, causing disturbance to ecosystems. Owing to an extracellular and non-specificenzymatic system produced by whiterot fungi, degradation of these xenobióticos became a viable alternative for environmental bioremediation. Such lignino

7. Microbial degradation of xenobiotic, aromatic pollutants in humic water.
The microbial degradation of a number of 14C-labeled, recalcitrant, aromatic pollutants, including trichloroguaiacol and di-, tri-, and pentachlorophenol, was investigated in aquatic model systems in the laboratory. Natural, mixed cultures of microorganisms in the water from a brown-water lake with a high content of humic compounds mineralized all of the tes

8. Degradation of 1,2,3,4-Tetrachlorobenzene by Pseudomonas chlororaphis RW71
Pseudomonas chlororaphis RW71 mineralized 1,2,3,4-tetrachlorobenzene, a highly recalcitrant pollutant hitherto not known to be degraded by pure cultures, as a sole source of carbon and energy, thereby releasing stoichiometric amounts of chloride. The transient excretion of tetrachlorocatechol in the early growth phase suggests an initial attack by a dioxygen
