“…After sampling, both residues were dried at 40°C. They were subsequently dry sieved through a 1 mm sieve, as performed in previous pilot experiments [5,6,16], to prevent clogging in the flow spacers when scaling up. The removed fraction represented a 1% of the total initial mass [16].…”

“…The pH range is a crucial criterion because of the pH differences between the compartments. MSWI residues, found in compartment III, had a considerable alkalinity [3,15,16]. Contrarily, the solutions in the other compartments were kept in an acidic range as explained in the section 2.5.…”

“…Their results show that the transport of the same ion through the different IEMs can vary substantially among the different brands: up to a threefold for Na + and NO 3 -, up to a 1.3-fold for organic salts, and up to a fourfold for Cl-. Two different ion exchange membrane (IEM) brands have been used in different studies of ED upgrading of MSWI APC residues and FA: Ionics [9,14,15] and Neosepta [5,6,16]. The influence of the IEM brand used for ED treatment of MSWI residues has, however, never been investigated.…”

In the present work, three different commercial membrane brands were used in an identical electrodialytic cell setup and operating conditions, in order to reduce the leaching of metals and salt anions of two types of municipal solid waste incineration residues: air pollution control residues of a semi-dry flue-gas cleaning system and fly ashes from a plant with wet flue-gas cleaning system. The results showed a general reduction of the leaching in both residues after ED remediation. For the following elements, the leaching was found to be different after ED treatment depending on the membrane used, with statistical significance: • Air pollution control residues of the semi-dry flue-gas cleaning system: Cr, Cu, Ni, Pb, Zn; • Fly ashes from a plant with wet flue-gas cleaning system: Al, Ba, Cu, Ni, Zn, Cl, SO. Final leaching values for some elements and membranes, but not the majority, were below than those of certified coal fly ash (e.g. Al or Cr), a material which is commonly used in construction materials; at the same time, some of these values were reduced to below the Danish law thresholds on the use of contaminated soil in constructions. These results show the potential of ED as a technology to upgrade municipal solid waste incineration residues.

“…Targeted heavymetals were mostly Cd, Cu, Cr, Pb and Zn. Two recent works have expanded the range of target pollutants to include previously unreported substances, such as As, Mn, Mo, Sb, Se, V, Cl and SO 4 [10] and also organic pollutants polychlorinated dibenzop-dioxins [11]. But so far, no report exists on the effect of the ED treatment on mercury content in MSWI residues, and this missing information is crucial to properly assess possible reuse options.…”

Fly ash (FA) and Air Pollution Control (APC) residues collected from three municipal solid waste incinerators (MSWI) in Denmark and Greenland were treated by electrodialytic remediation at pilot scale for 8 to 10 h. The original residues and the treated material were analysed for mercury (Hg) in order to assess the influence of the electrodialytic treatment on the concentrations of this element. Mercury levels varied with the MSWI residue, ranging from 0.41 mg kg −1 in FA sample from electrostatic precipitator (ESP) to 8.38 mg kg −1 in MSWI residues from a semi-dry system with lime and activated carbon. Two distinct behaviours were observed for mercury as a result of the electrodialytic treatment. This element became enriched in the MSWI residues from the semi-dry system with activated carbon, whereas it decreased in ESP's and cyclone's FA. This work presents for the first time information about the effect of electrodialytic treatment on mercury levels and discusses the valorisation options for these MSWI residues.
