1. Determinação de hormônios estrógenos e progestágenos em amostras ambientais por GC-MS
Due to the constant increase in population, the level of pollution on the planet has grown mainly in aquatic environments. Some of these contaminants present regulation but a fraction of these, called "emerging", besides being continuously released into the environment without any control, have no regulation. Sex hormones are part of these emerging contamina

2. Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal
In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only t

3. Study of reuse and recycling of rapid filter backwash water from water treatment plant in independent close cycle system / Estudo de reuso e reciclagem de agua de lavagem de filtro rapido de estação de tratamento de agua, em sistema de ciclo fechado, independente
The project was developed with the aim of studying the treatment and the reuse of rapid filter backwash water for recycling in this role, within a closed cycle, under system independent of production activities of a water treatment plant. The system was assembled with a polymer blending unit, a gravel preliminary upflow filter and a dual layer filter(F3), si

4. Utilização de lírio amarelo (Hemerocallis flava) em sistemas alagados construídos para tratamento de esgoto doméstico / Use of yellow lily (Hemerocallis flava) in construtect wetlands for treatment of domestic sewage
The objective of the present study was to evaluate the performance of four constructed wetlands subsurface flow systems (CW), operated with different rates of application in the treatment of domestic sewage. The experiment was conducted at the Experimental Area for Treatment of Municipal Waste, Department of Agricultural Engineering, Federal University of Vi

5. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

6. Avaliação da produção de odor na estação de tratamento de esgoto Paranoá e seus problemas associados
The Federal District of Brazil has been suffering problems of emanations of odors proceeding from sewage treatment plants (STP). For this reason, this work has the objective of evaluating the production of odor in the Paranoá sewage treatment plant (Paranoá STP), in Federal District, and its associated problems, employing hydrogen sulfide (H2S) as an indic

7. Concepção e estudo de uma unidade compacta para tratamento preliminar de esgoto sanitário composta por separador hidrodinâmico por vórtice e grade fina de fluxo tangencial / Designing and study of a compact unit for sewage preliminary treatment made up of a hydrodynamic vortex separator and a tangential flux fine screen
Atualmente, existe uma tendência entre os projetistas brasileiros de valorizar a etapa de tratamento preliminar em projetos de novas estações de tratamento de esgoto (ETE). Neste ensejo foi concebido, construído e estudado um protótipo, em escala plena, de uma unidade composta de separador hidrodinâmico por vórtice (SHV) empregado como desarenador

8. Evaluation of the anaerobic biodegradability of sewage sludge stabilized by anaerobic reactors / Avaliação da biodegradabilidade anaerobia de lodos de esgoto provenientes de reatores anaerobios sequenciais
The potential of applicability of an anaerobic process can be evaluated from the knowledge of some characteristics of the residues to be treated. A preliminary evaluation of these characteristics can assist in the choice of a more suitable treatment system, what allows to estimate the production of biological solids, requirements for nutrients, methane produ

9. Estudo da secagem de lodo de esgoto atraves da fritura de imersão
The increase in the population and in industrialization resulted in an increase in the volume of wastes. Part of these wastes is the wastewater and its treatment is a basic necessity of any society. Wastewater treatment generates large amounts of residues sewage sludge - that must be treated as well due to its dangerous nature and its large quantities. The o

10. Recovery of Small Quantities of Viruses from Clean Waters on Cellulose Nitrate Membrane Filters
A method is described for quantitatively recovering small amounts of viruses from large volumes of buffered, distilled water. Development of the method was motivated by the anticipated need for testing large volumes of renovated sewage for viruses. The method consists of adsorbing viruses onto cellulose nitrate membrane filters (0.45 μm pore size) from wate
