1. PHYSICAL, MECHANICAL AND THERMAL BEHAVIOUR OF ADOBE STABILIZED WITH THE SLUDGE OF WASTEWATER TREATMENT PLANTS
ABSTRACT The need for treated water is essential for life. With the constant increase in population, the most common way to purify surface water is through conventional water treatment plants (WTPs). The high volume of residue (sludge) generated in this process is most often returned to the catchment site, negatively affecting the ecosystem. The sludge of WT

3. Physico-chemical characterization of centrifuged sludge from the Tamanduá water treatment plant (Foz do Iguaçu, PR)
ABSTRACT The water treatment process generates a residue called water treatment plant (WTP) sludge, which needs to be correctly characterized to ensure appropriate disposal or reuse. This study aimed to characterize the centrifuged sludge produced at the Tamanduá WTP, Iguaçu Falls City, Brazil, and considered opportunities for its reuse in the production o

4. Polymerase chain reaction and nested-PCR approaches for detecting Cryptosporidium in water catchments of water treatment plants in Curitiba, State of Paraná, Brazil
Introduction Cryptosporidium is an important protozoan cause of waterborne disease worldwide of concern to public health authorities. To prevent outbreaks of cryptosporidiosis, the monitoring of this parasite in drinking water is necessary. In the present work, the polymerase chain reaction (PCR) and nested-PCR techniques were used to detect Cryptosporidium

5. Receiving WTP sludges in WWTP by activated sludge operating with plastic medium in the aeration tank (MBBR). / Recebimento de lodo de ETA em ETE por lodo ativado operando com mídia plástica no tanque de aeração (MBBR).
O tratamento do lodo gerado em estações de tratamento de água para abastecimento (ETAs) é uma questão a ser equacionada em todo o território nacional. O tratamento desses lodos em estações de tratamento de esgoto (ETEs) é uma alternativa a ser estudada, pois pode levar a uma solução eficaz e de custos reduzidos se compararmos aos custos de implant

6. Tratamento de água para abastecimento público por sistema de separação por membrana de ultrafiltração: estudo de caso na ETA Alto da Boa Vista (São Paulo, SP). / Drinking water treatment by ultrafiltration: case study at Alto da Boa Vista WTP(São Paulo- SP).
Membrane processes, specially microfiltration and ultrafiltration, are emerging technologies for drinking water treatment due the possibility for producing high quality water through compact treatment plants that are easier to automate with reduced sludge production and cost competitive compared with conventional processes. In this research it had been evalu

7. Estudo das micropropriedades de resíduos sólidos gerados nos decantadores de estações de tratamento de água
The conventional or life-cycle system for water treatment (chemical coagulation, flocculation, sedimentation, filtration, disinfection, fluoridation and pH correction) employed in most water treatment plants (WTP) in Brazil turns water unfit for human consumption (spring water and surface water) into a product that is in accordance with the drinking water gu

8. Análise da adição de resíduo oriundo do tratamento de esgotos em massa cerâmica utilizada para fabricação de telhas
Sludge of Wastewater Treatment Plants (WTPs) disposal is a problem for any municipality, for this reason the amount of sludge production is now a key issue in selecting treatment methods. It is necessary to investigate new applications for this waste type, due to the restrictions imposed by the environmental organs. The raw materials used in the Red Ceramic,

9. 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

10. Resíduos agrotóxicos em lodo de estação de tratamento de água para consumo humano: validação de metodologia analítica utilizando cromatografia líquida acoplada à espectrometria de massas em tandem (LC-MS/MS) / PESTICIDES RESIDUES IN WATER TREATMENT PLANT SLUDGE: VALIDATION OF ANALYTICAL METHODOLOGY USING LIQUID CHROMATOGRAPHY COUPLED TO TANDEM MASS SPECTROMETRY (LC-MS/MS)
The evolving scenario of Brazilian agriculture brings benefits to the population and demands technological advances to this field. Constantly, new pesticides are introduced encouraging scientific studies with the aim of determine and evaluate impacts on the population and on environment. In this work, the evaluated sample was the sludge resulted from water t

11. Avaliação da qualidade do Rio São Lourenço, SP, sob influência de estações de tratamento de água e estações de tratamento de esgoto / ENVIRONMENTAL QUALITY IN AREA OF INFLUENCE OF MUD OF STATIONS FOR TREATMENT OF WATER AND SEWAGE
For a long time, there was a neglect to water resources, both by society as by the authorities. The rapid increase of population, causing disorderly occupations, was ignored by the public sectors and the society itself, resulting in environmental degradation. Ecotoxicological tests are essential to environmental assessment, together with chemical and biologi

12. 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
