Multiphysics Implementation of Electrokinetic Remediation Models for Natural Soils and Porewaters

Models of electrokinetic soil remediation systems have been developed significantly in recent decades. A wide range of physicochemical phenomena occurs in this type of process, which makes it difficult to capture all of the system’s complexity in a model. Therefore, existing models do not attempt to...

En este tipo de procesos ocurre una amplia gama de fenómenos fisicoquímicos, lo que dificulta capturar toda la complejidad del sistema en un modelo. Por lo tanto, los modelos existentes no intentan simular el comportamiento de todo el sistema geoquímico de los suelos naturales y sus poros, sino que se centran en el contaminante .compuestos de interés. Este artículo propone un modelo conceptual y numérico que incluye especiaciones geoquímicas diferentes a los fenómenos que han sido descritos por otros autores. Además, se realiza un ejercicio de modelado comparativo con una composición de agua mineral natural y una composición equivalente simplificada. Los resultados muestran que el sistema amortiguador de los carbonatos afecta la evolución temporal y la distribución espacial del pH. Debido a que el pH controla muchos de los fenómenos que ocurren durante este tipo de remediación, las simulaciones que utilizan sistemas geoquímicos realistas son fundamentales.Elsevier202220222017info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29753reponame:RUIdeRA.
