1. Using Polymer Reaction Engineering Principles to Help the Environment: The Case of the Canadian Oil Sands Tailings
The Canadian oil sands reserves are an important national resource with a large impact on the Canadian economy. Unfortunately, oil sands extraction processes generate toxic by-products called mature fine tailings that need to be stored in disposal ponds for a very long time before the land can be reclaimed. This serious environmental liability needs to be ad

2. Identification of circo-like virus-Brazil genomic sequences in raw sewage from the metropolitan area of São Paulo: evidence of circulation two and three years after the first detection
BACKGROUND Two novel viruses named circo-like virus-Brazil (CLV-BR) hs1 and hs2 were previously discovered in a Brazilian human fecal sample through metagenomics. CLV-BR hs1 and hs2 possess a small circular DNA genome encoding a replication initiator protein (Rep), and the two genomes exhibit 92% nucleotide identity with each other. Phylogenetic analysis b

3. Métodos clássicos e moleculares para avaliação da qualidade virológica de lodo de esgoto e de água de reúso: determinação da eficiência e limites de detecção. / Standard and molecular methods for surveillance of human enteric viruses in sludge and reclaimed water: efficiency and detections limits.
Os vírus entéricos humanos são encontrados no esgoto e em subprodutos dos processos de tratamento. Recentemente vem sendo recomendados como indicadores de qualidade microbiológica em normas da legislação brasileira e também nas de outros países, mas ainda com parâmetros a definir. O objetivo do estudo é a avaliação e a comparação entre métodos

4. Study of potential impacts of using sewage sludge in the amendment of desert reclaimed soil on wheat and jews mallow plants
This investigation was conducted to study the impacts of using sewage sludge at different concentrations (0, 10, 25, 50, 75%) in amendment of desert reclaimed soil properties and some physiological aspects in wheat and jews mallow plants. Generally adding sewage sludge to desert soil improved the soil texture, raised the organic matter contents, water holdin

5. Assessment of Methods for Detection of Infectious Cryptosporidium Oocysts and Giardia Cysts in Reclaimed Effluents
This study evaluates the occurrence of Cryptosporidium oocysts and Giardia cysts in reclaimed effluents if method 1623 with the Envirochek capsule filters (standard and high-volume [HV] filters) and a modified version of the Information Collection Rule method (ICR) with the polypropylene yarn-wound cartridge filter are used. The recovery efficiency of the an

6. Detection of Legionella species in reclaimed water and air with the EnviroAmp Legionella PCR kit and direct fluorescent antibody staining.
Reclaimed water is an important resource for areas with inadequate water supplies. However, there have been few studies on the variety of microorganisms found in this type of water, since typically reclaimed water is examined only for the presence of coliform bacteria. Many microorganisms, including the legionellae, are known to be more resistant to chlorine

7. Infectious Cryptosporidium parvum Oocysts in Final Reclaimed Effluent
Water samples collected throughout several reclamation facilities were analyzed for the presence of infectious Cryptosporidium parvum by the focus detection method-most-probable-number cell culture technique. Results revealed the presence of infectious C. parvum oocysts in 40% of the final disinfected effluent samples. Sampled effluent contained on average s

8. Evaluation of Slime-Producing Bacteria in Oil Field Core Flood Experiments
Epifluorescence microscopy and carbohydrate determinations indicated that the decrease in permeability of oil reservoir sand to reclaimed sewage water was partially the result of biological plugging. Filtration and biocide addition studies demonstrated that the increase in bacterial densities and slime concentrations in flooded oil field cores appeared to be

10. Evidence for the Presence of Simkania negevensis in Drinking Water and in Reclaimed Wastewater in Israel
Simkania negevensis is a recently discovered chlamydia-like intracellular microorganism which has been associated with bronchiolitis in infants and with community-acquired pneumonia in adults; a high seroprevalence of antibodies to the microorganism has been found in various population groups. S. negevensis can be grown in various cell lines as well as in fr

11. Development and Application of a Bioluminescence-Based Test for Assimilable Organic Carbon in Reclaimed Waters▿
Assimilable organic carbon (AOC) is an important parameter governing the growth of heterotrophic bacteria in drinking water. Despite the recognition that variations in treatment practices (e.g., disinfection, coagulation, selection of filter media, and watershed protection) can have dramatic impacts on AOC levels in drinking water, few water utilities routin

12. Rapid detection of bacterial endotoxins in drinking water and renovated wastewater.
A pilot study was conducted to determine the feasibility of using the Limulus endotoxin assay to detect endotoxins in potable waters and from reclaimed advanced waste treatment (AWT) plant effluents. Water samples were tested using both Limulus lysates prepared in our laboratory and a commercial product, Difco Pyrotest. The Limulus assay procedure was easily
