Investigations of Carbapenem-resistant Klebsiella species and associated clinical considerations
… Thirty-two bacteriophages were isolated from sewage water and found to infect one or more of the clinical Klebsiella isolates. Some phages with broad host ranges (i.e. they infected K. pneumoniae, K. michiganensis, K. variicola and K. grimontii strains) were identified, which may have use in …

Sewage, salt, and sediments: water-quality assessment of the lower Vaal-Orange River system
ENGLISH ABSTRACT: Water users in the lower Vaal-Orange River system are subjected to chemicals and pathogens from sources over which they have little control. These sources include raw sewage from dysfunctional wastewater-treatment works, saline irrigation return flows and upstream discharges from …

Propuesta de mejoramiento de capacidad hidráulica del emisor submarino de la PTAR La Chira mediante el uso del coeficiente de contracción de las válvulas de retención tipo Duckbill en el tramo difusor
Los emisores submarinos son preferibles para la descarga de aguas residuales domesticas tratadas, debido a la capacidad de asimilación del mar como una opción más económica. Si se eligen los sistemas de salida al mar, la ubicación es fundamental para evitar el retorno de las aguas residuales a la …
