Electrodialytic remediation of creosote and CCA treated timber wastes
2002 - IRG/WP 02-50190
There is a growing concern about the environmental issue of impregnated timber waste management, since an increase in the amount of waste of treated wood is expected over the next decades. Presently, no well-documented treatment technique is yet available for this type of waste. Alternative options concerning the disposal of treated wood are becoming more attractive to study, especially the ones ...

Soil contamination at the wood preservation industry: Treatment technologies
2001 - IRG/WP 01-50166-16
The soil is a specific compartment of the biosphere, because it is not only a geochemical sink for contaminants, but it also acts as a natural buffer, controlling the transport of chemical elements and substances to the atmosphere, hydrosphere, and biota. Soil contamination problems are expected at wood preservation sites, particularly at those which use(d) inorganic wood preservatives or creosote...

Electrochemical removal of Cu, Cr and As from CCA-treated waste wood
2001 - IRG/WP 01-50166-18
CCA-treated waste wood poses a potential environmental problem due to the content of copper, chromium and arsenic. This paper presents the results obtained by electrodialytic remediation of CCA-treated waste wood. It is found that more than 90% Cu, and approximately 85% Cr and As was removed from the wood during the remediation. Thereby the concentration of copper in the wood is reduced from app. ...

Electrodialytic remediation of a soil from a wood preservation industry polluted by CCA
1998 - IRG/WP 98-50101-14
Soil contamination is often found at wood preservation sites due to spills, dripping of excess preservatives and deposition of sludge associated with dissolved salts of copper, chromium and arsenic (CCA). The electrodialytic process is a promising heavy metal soil remediation technique. It is based on a combination of the electrokinetic movement of ions in soil with the principle of electrodialysi...

Wood preservation sites polluted by CCA. Is potassium diphosphate incubation a catalyst for the electrodialytic remediation of these soils?
1998 - IRG/WP 98-50106
As part of an evaluation of a newly developed electrodialytic soil remediation technique, we investigated the incubation of a contaminated soil (from a Portuguese wood preservation site polluted with CCA) with potassium diphosphate as a possible catalyst for the removal of heavy metals and metalloids. A chemical sequential extraction scheme (SE) applied to the soil has shown that the potassium dip...
