Analysis of sludge using proton induced x-ray emission

Resumen
Inglés
Español
Regulations to control the huge amounts of sludge produced by wastewater are needed. Sludge generated in conventional sedimentators or anaerobic digestors were characterized by Protoii Induced X-ray Emission (PIXE). It was possible to determine the presence of macronutrient elements, such as P and K, and secondary nutrients like Ca, S, and Mg. Moreover, heavy elements like Cu, Zn, and Pb were also found. The sludge treatment in anaerobic digestors increased the amount of certain elements Al, Si, S, CI, and K; decrease in Ca, Ti, and Cu, and no change in V, Cr, and Zn. Possible uses of this sludge are also suggested.
