“…With the constant evolution of software, modeling waste stabilization ponds could experience further advancement. Sah et al (2012) agreed with this sentiment. In addition, the authors recommended that upto-date full-scale data should be available to verify the accuracy of the models (Sah et al 2012).…”

“…CFD models the performance of the pond in removing nutrients, BOD, sedimentation, and pathogens. CFD can vary with meteorological conditions, pond orientation, and design adjustments (Sah et al 2012). CFD benefits the researcher insomuch as he or she is able to determine how varying the effects of conditions within waste stabilization ponds would affect the performance of removing various constituents.…”

“…This has led to an urgent need to manage large volumes of biosolids under the increasingly strict environmental regulations and license operation conditions imposed upon water utilities and other wastewater operators. The hydraulic inefficiency of WSPs is a problem that increases in severity over time, as long-term hydraulic performance of ponds is increasingly compromised as sludge accumulates, which results in reduced effective treatment volume and changes in bottom bathymetry (Nelson, Cisneros, Tchobanoglous, & Darby, 2004;Olukanni & Ducoste, 2011;Peña, Mara, & Sanchez, 2000;Persson, 2000;Persson, Somes, & Wong, 1999;Persson & Wittgren, 2003;Sah, Rousseau, & Hooijmans, 2012). In turn, the build-up of sludge in these systems contributes to the complexity of pond hydrodynamics (Faleschini, Esteves, & Valero, 2012); for example, pond features such as channels can result in short-circuiting of flow and reduced mean hydraulic residence time (Figure 3).…”

“…La eficiencia media de remoción de la DBO fue del 76,6%, inferior a la mínima establecida por la legislación ambiental brasilera. El número más probable de coliformes fecales en el efluente fue de 6,34x10 5 /100mL, que superó en gran medida los valores máximos permitidos para vertimientos en cuerpos receptores. La planta requiere de la implementación de un sistema de pre-tratamiento, de la remoción de los lodos acumulados en las zonas más críticas y la implementación de un sistema de postratamiento que garantice remoción adicional de DBO y coliformes para ajustarse a la normatividad ambiental.…”

“…Según Peña y Mara [4], las lagunas de estabilización son usualmente el más apropiado método para el tratamiento de AR domésticas y municipales en países en vías de desarrollo, donde el clima es más favorable para su operación. Estas presentan alta eficiencia y funcionamiento totalmente natural altamente sustentable; usualmente requieren bajos costos de inversión y poseen bajos costos de operación y mantenimiento [5]; de igual manera, asimilan grandes variaciones de caudal y realizan el tratamiento con eficiencias similares a las logradas por los sistemas convencionales, produciendo un efluente altamente purificado con costos muy inferiores [1].…”
