Analysis of sludge using proton induced x-ray emission
Regulations to control the huge amounts of sludge produced by wastewater are needed. Sludge generatedin conventional sedimentators or anaerobic digestors were characterized by Protoii Induced X-ray Emission(PIXE).

| Sumario: | Regulations to control the huge amounts of sludge produced by wastewater are needed. Sludge generatedin 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, andsecondary 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, andK; decrease in Ca, Ti, and Cu, and no change in V, Cr, and Zn. Possible uses of this sludge are alsosuggested. |
