Leaching Behavior of Lead from Ultrasonically Treated MSWI Fly Ash

Journal of Environmental Science and Health, Part A, 2004
This study was conducted to evaluate the effect of ultrasound widely used for extraction of contaminants and for synthesis of complexes, on extraction and stabilization of heavy metals in MSWI fly ash. Ten grams of fly ash was treated at 10 of liquid--solid (L/S) ratio with and without ultrasonic irradiation of 20 kHz. The extractability of Pb from fly

Preparation of the saving-energy sulphoaluminate cement using MSWI fly ash

Journal of Hazardous Materials, 2009
MSWI fly ash was used as a major cement raw material in sintering sulphoaluminate cement clinker successfully in the laboratory. Sintering system, mechanical performance, hydration process and microstructure of the clinker was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence spectrometry (XRF), etc.

Application of MSWI fly ash on acid soil and its effect on the environment

Waste Management, 2008
This study evaluated the feasibility of using municipal solid waste incinerator (MSWI) fly ash as acid soil amendment. In particular, changes in soil physicochemical properties and the potential environmental problems caused by the application of MSWI fly ash were investigated.

Mineral transformation and solidification of heavy metals during co-melting of MSWI fly ash with coal fly ash

Environmental Science and Pollution Research
Melting is an efficient method to turn municipal solid waste incineration (MSWI) fly ash (FA) into non-hazardous material. Coal fly ash (CFA) was selected as the silica-alumina source to carry out co-melting research with MSWI FA in this work. The effects of the temperature and the CFA content on mineral transformation and the migration characteristics

Recycling MSWI bottom and fly ash as raw materials for Portland cement

Waste Management, 2008
Municipal solid waste incineration (MSWI) ash is rich in heavy metals and salts. The disposal of MSWI ash without proper treatment may cause serious environmental problems. Recently, the local cement industry in Taiwan has played an important role in the management of solid wastes because it can utilize various kinds of wastes as either fuels or raw ...

Comparative life cycle assessment of MSWI fly ash treatment and disposal

Waste Management, 2018
Municipal solid waste incineration (MSWI) fly ash constitutes a hazardous waste. The possibilities for managing this waste comprise disposal at underground deposits or at above-ground landfills after cement stabilisation, application of the FLUREC process, thermal treatment in a dedicated furnace or thermal co-treatment together with combustible ...

Kinetics of carbon degradation and PCDD/PCDF formation on MSWI fly ash

Chemosphere, 2009
The native carbon oxidation and PolyChloroDibenzo-p-Dioxins and PolyChloroDibenzoFurans, PCDD/F, formation were simultaneously studied at different temperatures (230-350 degrees C) and times (0-1440 min) in order to establish a direct correlation between the disappearance of the reagent and the formation of the products. The kinetic runs were conducted

Mechanical activation of fly ash from MSWI for utilization in cementitious materials

Waste Management, 2019
In the present study, the physicochemical characteristics of municipal solid waste incineration fly ashes (FA) from circulating fluidized bed (CFB) or grate furnaces are studied in detail. It is identified that the CFB FA, containing high amount of Si and Al, has better potential and properties for utilization than the grate FA, which is much richer in

Disposal of MSWI fly ash through a combined washing-immobilisation process

Journal of Hazardous Materials, 2003
The objective of this work was to investigate the feasibility of a combined washing-immobilisation process as a means of optimising the disposal of fly ash resulting from municipal solid waste incineration (MSWI) in cementitious matrices. Two different types of Italian MSWI fly ash and an ordinary Portland cement (ASTM Type I) were used.
