The objective of this study is to investigate the treatment path of metals during the plasma vitrification of fly ash, bottom ash, sludge, and activated carbon collected from a laboratory waste treatment plant. Sampling, digestion, and analysis procedures that followed the standard methods of the Taiwan Environmental Protection Administration were used to determine the composition of the input and output materials. The microstructure was qualitatively examined using a scanning electron microscope. The results show that the vitrification process successfully vitrified the toxic input materials into a stable, glassy, amorphous slag. During vitrification, metals with low boiling points (As, Cd, Hg, Pb, and Zn) were vaporized into the flue gas. Metals with high boiling points and high specific weights went into the ingot, and the residual metals remained in the molten materials as the slag. The distribution of metals shows their behavior during vitrification and can provide a reference for vitrifying hazardous materials.
We introduce a model for population
Dynamics under mutualism inspired by the logistic equation but avoiding
Singularities. The model is mathematically simpler than the widely used type II
Models, although it shows similar complexity in terms of fixed points and
Stability of the dynamics. Furthermore...
We are still far from fully understanding their
Origin and stability. Theories invoking magnetic field have been formulated to
Help explain the stability of filaments; however, observations are needed to
Test their predictions. In this paper, we investigate the structure and radial
Equilibrium of fi...
We focus on the implementation of demand response strategy to
Save power during peak hours by using Smart Grid. It is obviously impractical
With centralized power control network to realize the real-time control
Performance, where a single central controller measures the huge metering data
