Analysis of Sewage and Sewage Sludge

Introduction

Recently, the increase in sewage sludge generated in the processing of sewage is becoming a problem due to sewage system dissemination and expansion of processing facilities. Sludge is normally incinerated or solidified and disposed of in landfills, or recycled for use in construction materials like concrete, or in fertilizer, etc. Therefore, it is necessary to investigate the levels of heavy metals in this sludge, or the danger of their leaching into the environment. This application introduces the quantitative analysis of sludge and sewage waste water using the multi-type ICPE-9000 ICP emission spectrometer. The ICPE-9000 is a highly sensitive ICP instrument equipped with the axial view as a standard function. By selecting the radial-view (option), simultaneous analysis of trace elements like cadmium, to high-concentration elements like iron, zinc and aluminum, etc. becomes possible. Moreover, as in the case of sewage sludge and waste water, even samples containing widely varying concentrations of the same elements can be measured simultaneously in a single batch.
