1. Cassava processing wastewater as a platform for third generation biodiesel production
ABSTRACT This study aimed to evaluate third generation biodiesel production by microalgae Phormidium autumnale using cassava processing wastewater as a platform. Experiments were performed in a heterotrophic bubble column bioreactor. The study focused on the evaluation of the bioreactor (batch and fed-batch) of different operational modes and the analysis of

2. Waste management focousing on industrial sustainability study case: petrochemical industries in Rio de Janeiro state / Gerenciamento de resíduos buscando a sustentabilidade industrial estudo de caso: indústrias petroquímicas localizadas no estado do Rio de Janeiro
This research has the aim of evaluating environmental management systems of five petrochemical industries in the State of Rio de Janeiro. This studys main focus is on the management of solid and liquid wastes which are generated during producing processes and the commitment with Brazilian laws applied to environmental protection. Following the development on

3. Development of alternative technology for wastewater treatment aiming the recovery of the water from car wash station / Desenvolvimento de tecnologia alternativa para tratamento de efluentes visando a reutilizaÃÃo da Ãgua de postos de lavagem de veÃculos
The increasing concern with the environment and specially with the use of the water resources resulted in the increasing valorization of the drinking water as well of consumption. Innumerable are the activities that use this resource, one of them, the Car Wash Station (CWS), object of this research. In Brazil, about 32,700 CWS approximately consume 3.7 milli

4. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

5. Modelagem matemática da degradação da glicose, com produção de hidrogênio, em um reator anaeróbio de leito fixo / Mathematical modeling of glycose degradation with hydrogen production in a fixed bed anaerobic reactor
Mathematical models bring benefits to the understanding of mechanisms involved on wastewater treatment processes because they provide interpretations and make possible performance predictions, evaluation of design alternatives, optimization of future plants or the improvement to existing systems. Therefore, in this work a mathematical model to describe the g

7. Diretrizes de gestÃo e tecnologia para o tratamento de efluentes industriais
From the second half of the last century onwards, an enormous industrial revolution started due to the increasing demands after the World War II. The industries needed to produce more, with more quality, and in lower time, to help the rebuilding of the countries involved in the conflict. Herewith, and in view of the exponential populational increase that occ
