1. COMBINING A SEQUENCING BATCH REACTOR WITH HETEROGENEOUS PHOTOCATALYSIS (TiO2/UV) FOR TREATING A PENCIL MANUFACTURER'S WASTEWATER
Abstract A Sequencing Batch Reactor (SBR) was combined with heterogeneous photocatalysis (TiO2/UV) as a tertiary treatment for a pencil manufacturer's wastewater. The SBR removed almost all Chemical Oxygen Demand (COD) from the wastewater, although color was barely removed. Photocatalysis was optimized using a factorial design. Final COD, Dissolved Organic C

2. Tratamento AnaerÃbio de Efluentes Contendo Corantes e Estudos de PÃs-Tratamento e Ecotoxicidade / Anaerobic Treatment of dye-containing Effluents and post-tratment and Toxicity Studies.
O descarte de efluentes tÃxteis em Ãguas superficiais representa um sÃrio problema ambiental e de saÃde pÃblica devido, principalmente, à presenÃa de corantes na sua composiÃÃo, muitos dos quais sÃo potencialmente tÃxicos e carcinogÃnicos. A remoÃÃo de cor e a mineralizaÃÃo de seus subprodutos à uma das maiores dificuldades enfrentadas pelas

3. Aplicação de fotólise direta e UV/H2O2 a efluente sintético contendo diferentes corantes alimentícios
Food industries employ a lot of synthetic dyes in their products. Most of these dyes are very stable face to the conventional treatments. This work studied the use of advanced oxidation process (AOP) as an alternative to the conventional ones to degrade a synthetic food effluent (photolysis and UV/H2O2 in continuous reactor). The more efficient process was t

4. 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

5. Combinaçäo de adsorçäo por carväo ativado com processo oxidativo avançado (POA) para tratamento de efluentes contendo fenol. / Combination of adsorption by activated carbon with advanced oxidation process (AOP) for the treatment of wastewater containing phenol.
O processo de adsorção por carvão ativado é uma técnica muito aplicada para tratamento de efluentes. Porém o tratamento que envolve adsorção não é um sistema completo, pois há a necessidade da destruição dos compostos que foram imobilizados na superfície do carvão. Frente a esse problema, métodos alternativos de regeneração de carvão ativa

6. Integration of microbiological treatment with immobilized cells and emerging (Advanced Oxidation Process) technologies for wastewater treatment generated in the textile industry. / Integração do tratamento microbiológico com células imobilizadas e tecnologias emergentes (Processos Oxidativos Avançados) para o tratamento de efluentes gerados na indústria têxtil.
The integration of different treatment processes in the degradation of textile wastewater was evaluated using precipitation technique, advanced oxidation processes (AOP) and aerobic biological treatment. AOPs (Ozone/UV and reagent of Fenton/UV) were evaluated in batch experiments according to a factorial planning L18 (Tagushi Method) in function of the flow

7. Treatment of wastewater containing chlorophenols by photo-Fenton advanced oxidation process. / Tratamento de efluentes aquosos contendo clorofenóis por meio de processo oxidativo avançado foto-Fenton.
In recent years, advanced oxidation processes (AOP) have emerged as potentially powerful methods to transforming organic pollutants into harmless substances. The present work aims to study the degradation of chlorophenols (2,4-dichlorophenol and pentachlorophenol) in aqueous solution by the photo-Fenton process. The experiments were conducted in a batch recy

8. Tratamento de efluentes da indústria de processamento de carnes utilizando flotação por ar dissolvido e processos de oxidação avançada
The use of wastewater treatment processes with high efficiency of organic matter removal is considered one of the most important steps to achieve lower pollution loads in meat processing industries. As a primary treatment, dissolved air flotation processes (DAF) using coagulation-flocculation are generally applied. Additionally, the utilization of high effic

9. Aqueous Congo Red degradation induced by plasma with glow discharge electrolysis / Degradação do corante Vermelho Congo em solução aquosa através de plasma obtido por eletrólise de alta tensão
Due to the concern with environmental impact and the need for the use of dyes for the textile industries, during the last years several studies has been undertaken to develop new technologies for energetic treatments that allow the degradation of compounds present in industrial waste. In this present work, the construction of a system for degradation of orga

10. Estudo da degradação dos antibióticos beta-lactâmicos amoxicilina e ampicilina e avaliação da toxicidade e biodegradabilidade dos seus produtos / Degradation of the pharmaceuticals amoxicillin and ampicillin and evaluation of toxicity and biodegradability of derived-products.
The presence of active pharmaceutical substances and personal-care products in aquatic environment has been a great concern for the scientific community. Pharmaceutical industries are one of the main sources of these types of compounds, which are characterized by low degradability and high toxicity. The antibiotic preparation may negatively affect living org

11. 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
