Las problemáticas regionales de la provisión de agua potable como objetivo de proyectos de laboratorio de Ingeniería Química

In many parts of Argentina, the provision of drinking water from underground sources is limited due to high concentrations of arsenic and fluoride. This issue was raised to senior Chemical Engineering students, to develop a treatment procedure based on known methods. For arsenic removal, a filter composed of an iron matrix coupled to a sand filter was built and tested, achieving a 90% reduction of arsenic levels. Removal of fluorine was performed using a packed bed of ground calcined bone, where the hydroxyapatite (its main component) acted as ion exchanger. During the development of the projects, the students had to decide on the selection of materials, design the experimental system and learn about the available analytical methods, with the ultimate goal of obtaining a transferable result to contribute to the solution of a regional problem.
