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. 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

4. 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

5. 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

6. 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,

7. 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

8. 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

9. Identificação da influência do descarte de lodo de estações de tratamento de água
The growing concern of environmental surveillance of the quality of hydric resources guides the development of research on management of residues generated in water treatment plants (WTP). Approximately 8.000 WTPs in Brazil operate without a treatment program of the residues, disposing these effluents in the environment. This work evaluated WTP discharges in

10. 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-

12. Work and hygiene safety in water treatment plants / Segurança e higiene do trabalho em estações de tratamento de agua
In places with human activities, such as Water Treatment Plants (WTP), there are many factors which can cause accidents: the use of various tools, noisy machinery without protection on mobile parts, chemical substances, slippery or irregular floors, unprotected electric devices, and entrance in unenough oxygenated places. When previously identified, these fa
