1. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

2. The effect of vinasse on the growth performance and feed digestibility of Holstein male calves
ABSTRACT. Industrial effluents of alcohol production are problematic for the environment. One of the proposed solutions to the reduction of harmful effects of the wastewater is to convert it into vinasse. The purpose of the present study is to investigate effects of rations with different levels of vinasse as a source of protein in the diet of 28 male Holste

3. Isolation and selection of microorganisms for the oily effluent remediation of the metalworking industry / Isolamento e seleção de microrganismos para remediação de efluente oleoso da indústria metal-mecânica
A indústria metal-mecânica é responsável pela síntese de um dos efluentes oleosos mais complexos e difíceis de tratamento e reuso. Esses efluentes são constituídos, entre outros poluentes, por fluidos de corte, que servem para refrigerar e lubrificar peças metálicas no sistema de usinagem. Quando esses efluentes são tratados biologicamente é impo

4. Caracterização de comunidades bacterianas mesófilas e termófilas em biorreatores a membrana durante o tratamento de efluentes de fábrica de papel reciclado / Characterization of mesophilic and thermophilic bacterial communities in membrane bioreactors during treatment of recycled paper mill effluents
Paper mils consume large quantities of water and thus generate high volume of effluents. Biological treatment of paper mils industrial effluent is widely used for this purpose. The new technology of membrane bioreactors under thermophilic conditions is still underused due to the lack of sufficient technical and scientific knowledge. In spite of their importa

5. Métodos emergentes para aumentar a eficiência do ozônio no tratamento de águas contaminadas
Many industrial processes produce effluents with a wide variety of xenobiotic organic pollutants, which cannot be efficiently degraded by conventional biological treatments. Thus, the development of new technologies to eliminate these refractory compounds in water has become very imperative in order to assure the quality of this important resource. Ozonation

6. APLICAÇÃO DO PROCESSO ELETROLÍTICO NO TRATAMENTO DE EFLUENTES DE UMA INDÚSTRIA PETROQUÍMICA / APPLICATION OF THE ELECTROLYTIC PROCESS IN THE TREATMENT OF WASTEWATER FROM A PETROCHEMICAL INDUSTRY
The petrochemical industry constitutes one of the most important industrial sectors in Brazil. The great diversity of processes of manufacture makes to increase the necessity of characterization of the effluents generated in each industrial plant. In general, the effluents presents high grade of organic matter, whose removal is necessary to expect to the tec

7. Uso de ozônio como pré e pós-tratamento de efluentes da indústria de celulose kraft branqueada / Pre and post ozone treatment of bleached kraft pulp mill effluents
This work evaluated the combination of ozone and activated sludge for treatment of bleached kraft pulp effluents. Ozonation was done before and after biological treatment. First the influence of pH, temperature and hydrogen peroxide dose on ozonation was assessed in order to optimize treatment efficiency, which was evaluated in terms of COD, BOD5, lignin, bi

8. Modelagem para remoção de metais pesados atraves de algas : analise para um componente em processos batelada e continuo
Effluents of many industrial processes carry high levels of heavy metals, which in great part are disposed in the water sources, polluting them. There are many treatments for these effluents, but one, specially, is gainning importance: the retention of heavy metals using algae. Algae are used in environment recovery promoting retention of heavy metals, in or

9. A redução de Cr (VI) sobre carbono vitreo reticulado : ensaios preliminares de sua remoção eletrolitica
Chromium, despite presenting a high toxic potential, is widely used in several industrial activities, especially in the finishing of metal ware. The concern for environmental issues has led to development of alternative methods for the treatment of the residues, since conventional treatments produce toxic sludge. The study of the reduction of Cr(VI) is aimed

10. Microscale and Molecular Assessment of Impacts of Nickel, Nutrients, and Oxygen Level on Structure and Function of River Biofilm Communities
Studies were carried out to assess the influence of nutrients, dissolved oxygen (DO) concentration, and nickel (Ni) on river biofilm development, structure, function, and community composition. Biofilms were cultivated in rotating annular reactors with river water at a DO concentration of 0.5 or 7.5 mg liter−1, with or without a combination of carbon, nitr
