Metallic iron: dawn of a new era of drinking water treatment research?
The goal of water treatment in water works is safe drinking water production. Various technological options are available to this end. However, many conventional water treatment technologies are too expensive for extensive ...
Elemental metals for environmental remediation: learning from cementation process.
The further development of Fe(0)-based remediation technology depends on the profound understanding of the mechanisms involved in the process of aqueous contaminant removal. The view that adsorption and co-precipitation ...
On nanoscale metallic iron for groundwater remediation.
This communication challenges the concept that nanoscale metallic iron (nano-Fe(0)) is a strong reducing agents for contaminant reductive transformation. It is shown that the inherent relationship between contaminant removal ...
Modeling the Permeability Loss of Metallic Iron Water Filtration Systems
Over the past 30 years the literature has burgeoned with in-situ approaches for groundwater remediation. Of the methods currently available, the use of metallic iron (Fe0) in permeable reactive barrier (PRB) systems is one ...
Investigating the processes of contaminant removal in Fe0/H2O systems
The instability of the premise of direct quantitative contaminant reduction by elemental iron (Fe0) materials in Fe0/H2O systems is pointed out. Recalled basic knowledge on aqueous iron corrosion shows that Fe0 surface is ...
Effect of pumice and sand on the sustainability of granular iron beds for the aqueous removal of CuII, NiII, and ZnII
Current knowledge of the basic principles underlying the design of Fe0 beds is weak. The volumetric expansive nature of iron corrosion was identified as the major factor determining the sustainability of Fe0 beds. This ...
On the suitability of admixing sand to metallic iron for water treatment
This communication clarifies the relationships between sand addition and the sustainability of iron/water systems for environmental remediation. It is shown that any enhanced contaminant removal in an iron/sand/water ...
Open Access. Freier Zugang zu wissenschaftlichen Publikationen - das Paradigma der Zukunft?
Since a couple of years there is a strong voice for open access – that is unrestricted free online access to research articles for everyone. By presenting a typology of open access, we discuss the realization of open access ...
Evaluation of the effects of shaking intensity on the process of methylene blue discoloration by metallic iron.
The term mixing (shaking, stirring, agitating) is confusing because it is used to describe mass transfer in systems involving species dissolution, species dispersion and particle suspension. Each of these mechanisms requires ...
