Item type:Publication, The challenges of wastewater reuse in Peru(Científica del Sur University, 2020-01-01)En el Per y, en particular, en la provincia de Lima se observa una situacin de mayor demanda hdrica y menor disponibilidad a causa de diversos factores, como son la distribucin asimtrica del recurso, el crecimiento demogrfico acelerado, los altos niveles de contaminacin de las aguas superficiales y subterrneas, entre otros, lo cual genera una situacin de escasez hdrica. Ante tal escenario, surge la imperiosa necesidad de implementar recursos alternativos a fin de generar una fuente adicional de suministro hdrico, que permita reducir la presin que se ejerce sobre las fuentes naturales y mejorar la calidad de los cuerpos receptores de agua, debido a la depuracin de las aguas residuales. En tal contexto, el presente artculo tiene por objeto dar alcances y propuestas frente a las siguientes interrogantes: cul es la solucin legislativa que se ha dado al problema de la contaminacin de las aguas en el pas, principalmente las aguas residuales de origen domstico sin depurar? y cul es la importancia de considerar a las aguas residuales tratadas como fuente de agua alternativa? En concreto, su finalidad estriba en el anlisis jurdico de la reutilizacin de las aguas residuales tratadas en el Per, a partir de una revisin del ordenamiento normativo que establece los aspectos tcnicos administrativos de su regulacin y gestin, en aras de mostrar su rgimen especial. Pero, previo a ello, resulta conveniente realizar un anlisis de las recomendaciones elaboradas por la Organizacin para la Cooperacin y el Desarrollo Econmico (OCDE) - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Parsimonious cumulative process-based workflow for early sanitation infrastructure evaluation (CPESI): Case study of Riohacha, Colombia(Elsevier Ltd, 2024-09-01)In small and medium-sized cities from developing countries, the early selection of integrated wastewater management systems is challenging due to the lack or limitations in the availability of basic information and skilled professionals. This study presents CPESI, a cumulative processes-based parsimonious workflow for early evaluation of sanitary infrastructure. CPESI is aimed to provide a simple, objective, and systematic analysis framework at the early stages of development of sanitary systems in underdeveloped nations. CPESI was applied to evaluate sanitation system alternatives for Riohacha (Colombia) in three stages, namely, (1) an initial assessment of citizens acceptability of the alternatives and analysis of basic laboratory testing; (2) a process analysis and technical-economic evaluation of alternatives based on CAPEX and OPEX indicators; and (3) engineering judgment to select the most viable alternative through multi-criteria evaluation. Our results suggest that CPESI could be highly replicable in developing countries and that it has the potential to expedite the alternatives assessment process when compared to data-intensive methods and expert requirements. Several researchers have highlighted the need to develop tools suitable to evaluate SDG 6 in developing nations. We believe that CPESI has the potential to contribute to that end. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, La supervisión ambiental en el sector saneamiento en el Perú: el caso de Ucayali(2024-12-20)El Perú, al igual que en diversos países de la región, es rico en recursos naturales, pero no obstante ello, su conservación se ve afectada por las diversas actividades económicas tales como la minería, la agricultura, la industria, la forestal y el saneamiento. Es esta última, la que es considerada como unos de los principales problemas ambientales que afecta a todo el país y en especial en los sectores ecosistemas frágiles como la selva peruana –como la región de Ucayali– o las fuentes de recursos hídricos, debido a una falta de control y vigilancia por parte de la entidad competente, es decir, por el Ministerio de Vivienda, Construcción y Saneamiento. Efectivamente, a pesar de la continua actuación del ministerio referido en el párrafo precedente, los problemas ambientales persisten y en algunos casos se han agravado, lo que se evidencia en los informes elaborados por la Organismo de Evaluación y Fiscalización Ambiental, ente rector del Sistema Nacional de Evaluación y Fiscalización Ambiental. Es así como, dentro de los problemas identificados que afectan a la adecuada fiscalización ambiental por parte de la entidad competente, tenemos a la incorrecta planificación ambiental que impacta negativamente en los resultados planteados por la entidad lo que impide la contribución o solución de los diversos problemas ambientales.Es así que el presente trabajo, luego de analizar el Sistema de Saneamiento y el Sistema Nacional de Evaluación y Fiscalización Ambiental, pretende identificar el problema que decanta en insuficiente e inadecuada fiscalización ambiental a cargo del Ministerio de Vivienda, Construcción y Saneamiento, proponiendo una solución que permita mejorar sus labores como entidad fiscalizadora. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Monitoreo de aguas residuales y evaluación del cumplimiento de valores máximos admisibles (VMA) en colectores primarios del área de drenaje de una planta de tratamiento(2023-07-26)The physicochemical monitoring and evaluation of wastewater in the critical drainage areas corresponding to the Puente Piedra WWTP, Lima, was carried out. For this purpose, the geographical position, the number of Non-Domestic Users (NDUs) and the identification of NDUs with high wastewater discharges were considered. In the critical areas, wastewater monitoring points were established, corresponding to sewage inlets, where quality was evaluated through compliance with the Maximum Allowable Values (MAV) of D.S. 021-2009- VIVIENDA. The monitoring plan covered a control period of 8 hours with spot monitoring carried out every 2 hours. At monitoring points BZ-70651 and BZ-59124, excess AMVs were found for pH (>14), BOD5, COD, TSS, oils and grease due to the presence of textile and paper manufacturing industries; at point BZ-212339 there was an excess of BOD5, COD, TSS, oils and grease, and sedimentable solids as a result of organic material released by businesses, restaurants and domestic users; at point BZ-46847 there was no excess of AMVs; and at point BZ-212344 BOD5 was exceeded due to discharges from businesses, domestic users and industries. It is recommended to extend the application of the regulations, considering the biological analysis parameters, improve UND control in the drainage area, establish continuous monitoring stations and replicate the described procedure to other areas. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Efficiency of Microorganisms in the Stabilization of Septic Sludge in the Huando District, 2021(Instituto de Altos Estudios de Salud Publica, 2023-03-01)The unprecedented growth of urban populations has placed enormous pressure on the quality of life with regard to housing, water and energy supply, and this is reflected in the deterioration of the quality of water, air and soil. A decrease in environmental quality due to the generation of waste in these urban centers, especially wastewater, is an important and growing concern. For this, improvement processes for these effluents have been proposed and one of them is the use of efficient microorganisms (EM), in the understanding that bacterial metabolism determines the effectiveness of biological treatment of wastewater. A protocol was designed with five treatments with three repetitions, a control or T0 without ME concentration, T1 2.5% ME in the V/V ratio (volume of solute and volume of solvent).; T2 5%; T3 7.5% and T4 10% to determine the effect of these bacteria in septic sludge in the Huando 2021 district. The organoleptic color and odor characteristics were substantially favored with the presence of ME. Likewise, the concentrations of dissolved solids, ammonium, biochemical oxygen demand; and very in particular, a considerable reduction of the colony-forming units of fecal coliforms. These systems are an alternative for wastewater treatment, they are economical, easy to install, operate and maintain, and are widely used to meet residential demands.
