Application of electrochemical methods in the removal of organic matter in the juices of the benefit of sisal products: biotechnological alternative for mitigating water pollution in the tributariesAplicación de métodos electroquímicos en la remoción de materia orgánica en los jugos producto del beneficio del fique: alternativa biotecnológica para mitigar la contaminación en los afluentes hídricos
(Universidad Colegio Mayor de Cundinamarca, 2011-12-15)
This research was intended to apply electroanalytical technologies, such as electrocoagulation for removal of organic matter present in sisal juices to reduce the environmental impact generated by age-old cultural practice such as the extraction of the fiber (sisal) of Fourcrea c. In the present study, we evaluated the behavior of chemical oxygen demand (COD) through an electrochemical process under different parameters ...
Periphytic Algae as Indicators of the State of the Water From an Urban Wetland in Jaboque, Bogotá, D.C., ColombiaMicroalgasperifíticas como indicadoras del estado de las aguas de un humedal urbano: Jaboque, Bogotá D.C., Colombia
(Universidad Colegio Mayor de Cundinamarca, 2006-12-15)
This study implemented the technique of colonization in artificial substrates during a period of seven months (November 2004 through May 2005). In the sector of greater urbanization of the wetland, the most representative group of microalgae were the euglenophytas and cyanophytas, with abundance an average of 20300 of indv/cm2. In the areas with lower anthropic intervention the diatoms were predominant, with an abundance ...
Composting Process Optimization of Post-Harvest Product (Cherry) Coffee With the Implementation of Native MicoorganismsOptimización del proceso de compostaje de productos post-cosecha (cereza) del café con la aplicación de microorganismos nativos
(Universidad Colegio Mayor de Cundinamarca, 2010-12-15)
Coffee growing brings the production of large amounts of post-harvest residues such as cherry. This waste causes environmental problems due to contaminated water sources, and generates changes in in the ecosystem if not properly treated. An alternative to this problem is the use of the cherry for the production of compost, reducing production costs. This study aims to reduce composting time of the coffee cherry using ...
Criteria for the application of environmental taxesCriterios de aplicación de impuestos ambientales
(Universidad Nacional Abierta y a Distancia, UNAD, 2021-10-19)
Taxes are recognized in the Mexican legal system as an obligation to contribute to public expenditures in order to satisfy a public need indirectly, that is, that the proceeds be applied for the payment of various public services. In the last decade, new taxes such as environmental or green taxes were introduced, due to climate change and the environmental pollution constantly generated by humans and companies, which ...
Alternatives for the stabilization of sludge generated in wastewater treatment plants from a systemic approach: a reviewAlternativas para la estabilización de lodos generados en estaciones depuradoras de aguas residuales desde un enfoque sistémico: una revisiónAlternativas para a estabilização de biossólidos gerados em estações de tratamento de águas residuárias, a partir de uma abordagem sistêmica.
(Sello Editorial UNAD, 2021-12-21)
Contextualization: Population growth and environmental problems at the local, national and international levels related to pollution from untreated sludge, due to the increasing volumes of such waste generated by wastewater treatment plants (WWTPs), increase environmental degradation.
Knowledge gap: There are deficiencies in the management of sewage sludge, attributable to a lack of knowledge of conventional and ...
