1. Implantação de tecnologias alternativas de saneamento como forma de garantir água de qualidade, quantidade e higiene no semiárido moçambicano : caso do distrito de Funhalouro
This work aimed at studying the hydrologic, hygiene and sanitation conditions in the district of Funhalouro, located in Inhambane province, Mozambique. This is a rural district characterized by semi-arid climate, with approximately 37,856 inhabitants, 8058 households and a population density of 2.78 inhabitants /km ². The water supply in the area of study i

2. Desinfecção solar de água para comunidades de baixa renda
A utilização da energia solar para desinfecção de água, além de ser acessível para comunidades menos favorecidas pelo seu baixo custo, tem a vantagem de utilizar materiais descartáveis como garrafas de politereftalato de etileno (PET). Apresenta-se um estudo que utilizou duas metodologias de desinfecção: a metodologia proposta pelo projeto Solar Wa

3. 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

4. Water solar disinfection using Escherichia coli and Clostridium perfringens as bioindicators / Desinfecção de águas naturais por radiação solar utilizando os bioindicadores : Escherichia coli e Clostridium perfringens
Latin-American countries are facing serious problems related to waterborne diseases due to the lack of basic sanitation, affecting in particular those people living in small and rural communities. Solar radiation for water disinfection, SODIS, seems a promising process for small communities since it does not require electric energy and it has low cost and ea

5. Inactivation of Escherichia coli in water by TiO2-assisted disinfection using solar light
Estudou-se a desinfecção de águas de abastecimento por fotocatálise heterogênea usando um reator de fluxo em um sistema composto por uma placa de vidro com TiO2 P 25 (Degussa) imobilizado e luz solar como fonte de radiação. Foram utilizados dois modos de operação do reator: passagem única e recirculação. Os experimentos foram conduzidos utilizand

6. Evaluation of a continuous flow disinfection system with water solar disinfection, chlorine and ultraviolet radiation / Avaliação de um sistema de fluxo continuo de desinfecção de agua por radiação solar, cloração e radiação ultra violeta
O presente artigo consiste no estudo do emprego de um sistema de aquisição de dados (DAQ) para o controle dos equipamentos de um sistema de desinfecção, conjugando desinfecção de água por radiação solar (SODIS), em fluxo contínuo, radiação ultravioleta e cloração. O uso de energia solar para desinfecção de água (SODIS) tem sido aplicado em p

7. Solar Disinfection Evaluation and its Social Viability at State of Ceará, Brazil / Avaliação do Processo de Desinfecção Solar (SODIS) e de sua Viabilidade Social no Estado do Ceará
Despite the importance of sanitation for well-being of the mankind and the natural resources conservation, still today a large number of people do not have access to wastewater system neither to public water supply. One technique which has being studied and applied in developing countries as a safe household water treatment method is solar disinfection, SODI

8. Disinfection of Contaminated Water by Using Solar Irradiation
Contaminated water causes an estimated 6 to 60 billion cases of gastrointestinal illness annually. The majority of these cases occur in rural areas of developing nations where the water supply remains polluted and adequate sanitation is unavailable. A portable, low-cost, and low-maintenance solar unit to disinfect unpotable water has been designed and tested

9. Development and Evaluation of a Reflective Solar Disinfection Pouch for Treatment of Drinking Water
A second-generation solar disinfection (SODIS) system (pouch) was constructed from food-grade, commercially available packaging materials selected to fully transmit and amplify the antimicrobial properties of sunlight. Depending upon the season, water source, and challenge organism, culturable bacteria were reduced between 3.5 and 5.5 log cycles. The system

10. Destruction of coliforms in water and sewage water by dye-sensitized photooxidation.
A new approach to disinfection of water and sewage water, by oxidative destruction of microorganisms by photosensitization, is described. Samples of water and sewage water, to which an inoculum of fecal Escherichia coli had been added, were exposed to solar radiation in the presence of a dye sensitizer, under continuous aeration. The effects of the sensitize

11. Inactivation of fecal bacteria in drinking water by solar heating.
We report simulations of the thermal effect of strong equatorial sunshine on water samples contaminated with high populations of fecal coliforms. Water samples, heavily contaminated with a wild-type strain of Escherichia coli (starting population = 20 x 10(5) CFU/ml), are heated to those temperatures recorded for 2-liter samples stored in transparent plastic
