1. Ozonation improves physical attributes in domestic sewage effluent
Resumo O Sistema de Zona de Raízes (SRZ) é uma opção natural de tratamento de efluentes amplamente estudado em todo o mundo, sendo uma tecnologia baseada em processos físicos, químicos e biológicos. No entanto, existem alguns atributos no efluente que ocasionalmente não são eliminados pelo SZR. Nesse contexto, o uso do ozônio pode contribuir para a

2. Adaptation of domestic effluent for agricultural reuse by biological, physical treatment and disinfection by ultraviolet radiation
Resumo O reúso de efluente doméstico é uma alternativa para a agricultura irrigada em situações de reduzida disponibilidade de água. No entanto, como é comum a presença de patógenos em águas residuárias, torna-se necessário um processo de desinfecção previamente à sua utilização. Com o desenvolvimento da pesquisa, avaliou-se a viabilidade sa

3. Septic tank combined with anaerobic filter and conventional UASB: results from full scale plants
Anaerobic digestion is an important alternative for domestic wastewater treatment, especially in warm climate regions. Two full-scale anaerobic schemes were investigated: septic tank combined with anaerobic filter (S T A NF) and conventional UASB reactors. Treated effluents from these systems were subjected to disinfection by chlorination. The operational pe

4. Treated domestic sewage: kinetics of Escherichia coli and total coliform inactivation by oxidation with hydrogen peroxide
Hydrogen peroxide has been used for decades in developed countries as an oxidizing agent in the treatment of water, domestic sewage and industrial effluents. This study evaluated the influence of the concentration of H2O2 and pH on the inactivation of Escherichia coli cells and the disinfection of sewage treated. The results showed that the inactivation rate

5. ESTUDO DO ÁCIDO PERACÉTICO NA DESINFECÇÃO DE ESGOTO SANITÁRIO: INFLUÊNCIA DAS CARACTERÍSTICAS FÍSICO-QUÍMICAS DO EFLUENTE, DETERMINAÇÃO DE CONCENTRAÇÃO RESIDUAL E CINÉTICA DE DEGRADAÇÃO
Este trabalho tem por objetivo estudar a utilização do ácido peracético (APA) na desinfecção de efluentes sanitários. Dentro desta perspectiva foram investigados: métodos para determinação do APA residual, os fatores que interferem na sua ação desinfetante, sua cinética de degradação no efluente e alguns possíveis subprodutos provenientes da

6. Sistema multicomutado de análise em fluxo para determinação de amônio e monocloramina em águas residuais e produtos de desinfecção
A binary sampling flow analysis system equipped with gas diffusion cell was developed for NH4+ and/or NH2Cl determination in wastewater and disinfection products samples based on the Berthelot reaction of the NH2Cl diffused through the semi-permeable PTFE membrane. The effect of the analytical conditions related to the reaction and flow parameters were evalu

7. 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

8. Characterization, treatment and reuse of greywater and rainwater use in buildings. / Caracterização, tratamento e reúso de águas cinzas e aproveitamento de águas pluviais em edificações.
The reuse of greywater and the rainwater catchment for non potable uses meets the premises of sustainability and the concept of water conservation. Properly conceived greywater reuse systems and rainwater catchment systems should follow four basic criteria: hygienic reliability, aesthetics, environmental protection and technical/economic feasibility. The gre

9. Controlled disposal of effluent domestic sewage in the ground a study of the reduction of fecal coliforms / Disposição no solo de efluentes de esgoto tratado visando a redução de coliformes termotolerantes
The indiscriminate launching in the water courses of sewers domestic without treatment, or exactly treat, but without appropriate disinfection, contributes with significant amount of organisms of the called "coliform group", between which specific agents of illnesses of water propagation can be present. The application of the effluent in the ground, instead

10. Formação de aldeídos e trialometanos da desinfecção por ozonização, cloração e ozonização/cloração de efluente de tratamento anaeróbio de esgoto sanitário / Aldehydes and trihalomethanes formation from desinfection in ozonization, chloration and, ozonation/chloration in anaerobic effluent from sanitary wastewater
The present work was mostly carried out in Brazil. However, aiming to enhance the research, a six-month data collection was performed at the Wageningen University - the Netherlands. The step carried out in Brazil proposed: to study the formation of by-products (aldehydes and trihalomethanes) from the disinfection of an anaerobic treatment wastewater effluent

11. Conductive diamond electrodes for water purification
Nowadays, synthetic diamond has been studied for its application in wastewater treatment, electroanalysis, organic synthesis and sensor areas; however, its use in the water disinfection/purification is its most relevant application. The new electrochemistry applications of diamond electrodes open new perspectives for an easy, effective, and chemical free wat

12. Avaliação da higienização do resíduo de caixa de areia de estações de tratamento de esgoto operadas pela CESAN
The process of treatment for wastewater produces solid waste that need to be constantly removed for to keep the treatments efficiency, amongst it, the waste deposited in the deep of the grit removal. The grit removal has the objective of to remove from wastewater the grit and others particulas, including the organics, presents in the wastewater in nature, th
