1. 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

2. Processo oxidativo avançado UV/H2O2 na oxidação da carbamazepina : avaliação por ensaios respirometricos e ecotoxicologicos / Advanced oxidation process UV/H2O2 in the oxidation carbamazepine : assessment with respirometry and ecotoxicological assays
O efeito da poluição é resultado inerente da ocupação humana com grande impacto ao ambiente. Um problema atual é a contaminação dos corpos d água com produtos de origem industrial, agrícola e produtos de origem farmacológica e de cuidado pessoal. Os fármacos são considerados contaminantes ambientais devido a estas moléculas serem biologicamente

3. APLICAÇÃO DE PROCESSOS OXIDATIVOS AVANÇADOS HOMOGÊNEOS E HETEROGÊNEOS NA DEGRADAÇÃO DE EFLUENTES DE CURTUME
This study investigated the application of advanced oxidative processes for the homogeneous and heterogeneous degradation of a tanning effluent. The catalytic activity of a solid oxide containing manganese was evaluated in the heterogeneous systems. The experiments were performed in a photocatalytic batch reactor in laboratory scale. The solid used was the c

4. "Wetlands construídos" de fluxo vertical com meio suporte de solo natural modificado no tratamento de esgotos domésticos / "Wetlands construídos" de fluxo vertical com meio suporte de solo natural modificado no tratamento de esgotos domésticos / Vertical flow constructed wetlands systems with substract of natural soil for domestic wastewater treatment / Vertical flow constructed wetlands systems with substract of natural soil for domestic wastewater treatment
In Brazil, the municipalities with sewerage system is 52,2% of the total (PNSB, 2000). Therefore, it is low figure and there are regional discrepancies, as the percentage of attendance at the southern and southeastern regions are higher then at the northern northeastern and middle western. The situation is even worse at the rural area, where most localities

5. Combinação de tratamento biológico aeróbio com processos oxidativos avançados visando intensificar a remoção de matéria orgânica em efluentes da indústria têxtil e de celulose kraft / Combining aerobic biological treatment and advanced oxidation processes to increase organic matter removal in textile and kraft pulp mill effluents
Bleached kraft pulp and textile effluents contain hard to degrade and, or toxic substances, and these industries often cannot meet legal limits for effluent chemical oxygen demand using conventional effluent treatment. Use of advanced oxidation processes (AOPs) is therefore being studied to treat their effluents. AOPs use a strong oxidizing agent to degrade

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

7. Estudo e projeto de reatores fotoquimicos para tratamento de efluentes liquidos / Study and design of photochemical reactors to treat liquid effluents
Wasterwater treatment has become a fundamental stage of industrial processes. Most wastewater treatment are currently based on biological processes. However, some types of wastewater cannot be treated by such processes due to the fact of possessing toxic. Therefore, the Advanced Oxidation Process (AOP) can be used with success in such wastewater remediation.
