1. Tratamento eletroquÃmico de esgotos sanitÃrios / Electrochemical Treatment for Municipal Sewage
Basic sanitation is a public service with the most deficiency in infrastructure in Brazil, in particular the service of collection and treatment of sewage followed by collection services and waste treatment. The scenary of sanitation in Brazil, especially in the big cities, it becomes increasingly costly and challenging because the population is increasingly

2. Aplicação do dióxido de cloro no tratamento de água para consumo humano: desinfecção para controle de oocistos de Cryptosporidium sp., formação de subprodutos e manutenção de residuais desinfetantes em sistemas de distribuição / Chlorine dioxide use in drinking-water treatment: disinfection control of Cryptosporidium sp., byproducts formation, and maintenance of disinfectant residuals in distribution systems
This work aimed at evaluating the use of chlorine dioxide in drinking-water treatment, with emphasis on byproducts formation, maintenance of disinfectant residuals in distribution systems and removal of Cryptosporidium oocysts. In jar test experiments, the application of chlorine dioxide in samples of raw water (simulating pre-oxidation), settled and filtere

3. Use of geographic information system in watershed management of water treatment plants sludge / Uso de sistema de informações geograficas na gestão do lodo das estações de tratamento de agua de uma bacia hidrografica
Present work investigates the use of geographic information system (GIS) - nowadays a necessary technique for spatial data analysis, broadly used as decision-making aid in many fields - as a tool for watershed management for disposal or beneficial use of water treatment plants (WTP) sludge. Most of times, residuals management is based in conventional data, c

4. The removal of dinitrochlorobenzene from industrial residuals by liquid-liquid extraction with chemical reaction
Nitrochlorobenzenes (NCBs) are very important in the chemical industry since they have been used as raw material for the manufacture of crop protection products, as active ingredients in the pharmaceutical industry, as pigments and as antioxidants as well as for other uses. In industrial processes, NCBs are produced by monochlorobenzene (MCB) nitration react

5. Effects of the accepting water treatment plants (WTP) residuals at wastewater treatment plant (WWTP) using SBR activated-sludge process with extended aeration in the city of Juquitiba, SP. / Efeitos do recebimento do lodo da estação de tratamento de água pelo sistema de tratamento de esgoto por lodo ativado em bateladas e aeração prolongada do município de Juquitiba - SP.
There are different technical engineering solutions for the treatment and final disposal of water treatment plants (WTPs) residuals. Discharge of WTP residual to a wastewater treatment plant (WWTP) is a technical solution in evidence. Therefore, the purpose of this study was to evaluate the capacity of the WWTP using sequencing batch reactor (SBR) activated-

6. Evaluation of throwing sludge generated on a treatment water station with an upflow anaerobic sludge blank reactor (UASB). / Avaliação da disposição de lodo gerado numa estação de tratamento de água em reator anaeróbio de fluxo ascendente e manto de lodo UASB.
Water treatment stations have the purpose of providing potable water. In this process of water treatment, a variety of residuals are produced; these, historically have been discharged into water streams, increasing the water pollution. The objective of this work was to evaluate the impact of discharging residuals in a treatment station with an Upflow Anaerob

7. Phosphorus removal in effluent of wastewater treatment plant with water treatment residuals (WTR). / Remoção de fósforo de efluentes de estações de tratamento biológico de esgotos utlizando lodo de estação de tratamento de água.
Phosphorus is considered as the main responsible for the nutritional enrichment of reservoirs of public drinking water supplies, because eutrophication process has resulted in toxic algae blooms, and therefore its removal has a great significance since these toxins represent a public health risk and environment. The aim of this research work was to evaluate

8. Chlorine resistance of poliovirus isolants recovered from drinking water.
Poliovirus 1 isolants were recovered from finished drinking water produced by a modern, well-operated water treatment plant. These waters contained free chlorine residuals in excess of 1 mg/liter. The chlorine inactivation of purified high-titer preparations of two such isolants was compared with the inactivation behavior of two stock strains of poliovirus 1

9. Rates of inactivation of waterborne coliphages by monochloramine.
A sophisticated water quality monitoring program was established to evaluate virus removal through Denver's 1-million-gal (ca. 4-million-liter)/day Direct Potable Reuse Demonstration Plant. As a comparison point for the reuse demonstration plant, Denver's main water treatment facility was also monitored for coliphage organisms. Through the routine monitoring

10. Bacterial nutrients in drinking water.
Regrowth of coliform bacteria in distribution systems has been a problem for a number of water utilities. Efforts to solve the regrowth problem have not been totally successful. The current project, which was conducted at the New Jersey American Water Co.-Swimming River Treatment Plant, showed that the occurrence of coliform bacteria in the distribution syst

11. Impacts of the Reduction of Nutrient Levels on Bacterial Water Quality in Distribution Systems
This study evaluated the impacts of reducing nutrient levels on bacterial water quality in drinking water. Two American Water System facilities (sites NJ102a and IN610) with histories of coliform problems were involved, and each water utility received two pilot distribution systems (annular reactors). One reactor simulated the conventional treatment conditio

12. Application of ribotyping for differentiating aeromonads isolated from clinical and environmental sources.
We have investigated the usefulness of ribotyping for the differentiation of aeromonads isolated from five patients with gastroenteritis and from the source water, treatment plant, and distribution system of a small public water supply. Aeromonas hydrophila and Aeromonas caviae were isolated from fecal specimens preserved in Cary-Blair transport medium by us
