Hydrothermal treatment of municipal solid waste incineration fly ash for dioxin decomposition

Journal of Hazardous Materials, 2012
Hydrothermal treatment of MSWI fly ash was performed in this paper with a purpose to reduce its dioxin content. First a hydrothermal reactor was set up with a mixture of ferric sulphate and ferrous sulphate serviced as the reactant, then the effects caused by reaction conditions such as reaction temperature, pre-treatment by water-washing and reactant ...

Leaching Characteristics of Heavy Metals in Municipal Solid Waste Incinerator Fly Ash

Journal of Environmental Science and Health, Part A, 2005
The potential release of Pb, Zn, Cr, and Cu in municipal solid waste incinerator (MSWI) fly ash was investigated by batch leaching experiments using sodium acetate solution as the extractant. The concentrations of heavy metals decreased against the increase of liquid-to-solid (L/S) ratio with the exception of Zn.

Solidification/stabilization and optimization of municipal solid waste incineration fly ash with aluminosilicate solid wastes

Journal of Environmental Management
Alkali-activation is an effective municipal solid waste incineration fly ash (MSWIFA) solidification/stabilization (S/S) technology. However, the characteristics of calcium-rich silica-poor aluminum phase in MSWIFA easily cause the structural instability and contamination of alkali activated MSWIFA S/S bodies.

Recycling of municipal solid waste incinerator fly ash by using hydrocyclone separation

Waste Management, 2013
The municipal solid waste incinerators (MSWIs) in Taiwan generate about 300,000 tons of fly ash annually, which is mainly composed of calcium and silicon compounds, and has the potential for recycling. However, some heavy metals are present in the MSWI fly ash, and before recycling, they need to be removed or reduced to make the fly ash non-hazardous ...

Study on Physicochemical Characteristics of Municipal Solid Waste Incineration (MSWI) Fly Ash

2009 International Conference on Environmental Science and Information Application Technology, 2009
This study aims to develop a methodology for analysis of physicochemical characteristics of municipal solid waste incineration (MSWI) fly ash. In this work, microstructure, particulate size distribution and components of fly ash were investigated using SEM, laser particulate description analyzer, ICP, XRF, IR and XRD.

Biotoxicity evaluation of fly ash and bottom ash from different municipal solid waste incinerators

Journal of Hazardous Materials, 2009
Different types of municipal solid waste incinerator (MSWI) fly and bottom ash were extracted by TCLP and PBET procedures. The biotoxicity of the leachate of fly ash and bottom ash was evaluated by Vibrio fischeri light inhibition test. The results indicate the following: (1) The optimal solid/liquid ratio was 1:100 for PBET extraction because it had ...

Fluidization-melting characteristics of fly ash from municipal solid waste incineration

Waste Management
Fly ash (FA) from municipal solid waste incineration contains hazardous substances such as dioxins, furans, and heavy metals. Melting FA has proved to be an effective method for reducing volume and mass, while also rendering the waste harmless. However, during the melting process, the addition of a fluxing agent with calorific value is currently ...

Sequestration of metals in carbonated municipal solid waste incineration (MSWI) fly ash

Waste Management, 2003
Waste management is in need of a reliable and economical treatment method for metals in fly ashes from municipal solid waste incineration (MSWI). However, no state-of-the-art technique has gained wide acceptance yet. This paper is a synthesis of five elsewhere published investigations covering a project which aimed to assess the possibilities and ...

Microbial Induced Solidification of Municipal Solid Waste Incineration Fly Ash

2018
To investigate the applicability of microbial induced calcite precipitation (MICP) to the solidification of municipal solid waste incineration (MSWI) fly ash, the following work are carried out. Firstly, three ureolytic strains, UR1, UR2 and UR3, were isolated and identified as Sphingobacterium cladoniae, Bacillus aryabhattai and Raoultella ...
