Metallic Iron for Water Treatment: A Critical Review
(2013)
Water treatment with metallic iron (Fe0) is still based on the premise that Fe0 is a reducing agent. An alternative concept stipulates that contaminants are removed by adsorption, co-precipitation and size-exclusion in a ...

Testing the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
(2013)
A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe0) was evaluated. A 2.0 mg L-1 methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity ...

Aqueous contaminant removal by metallic iron: Is the paradigm shifting?
(2011)
Chemical reduction has long dominated the thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe0/H2O systems). However, a large body of experimental evidence indicates that ...

Designing laboratory metallic iron columns for better result comparability
(2011)
Despite the amount of data available on investigating the process of aqueous contaminant removal by metallic iron (Fe0), there is still a significant amount of uncertainty surrounding the design of Fe0 beds for laboratory ...

Investigating the Release of Co-precipitated Uranium from Iron Oxides
(2006)
The removal of uranium (VI) in zerovalent iron permeable reactive barriers and wetlands can
be explained by its association with iron oxides. The long term stability of this immobilized U
is yet to be addressed. The ...

Metallic iron for water treatment: Healing a research community
(2014)
Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of ...

To Wait or Not to Wait? The Bicriteria Delay Management Problem in Public Transportation
(2007)
Assume that a train reaches a station with delay. At the station there
is a bus ready to depart. The question if such a bus should wait for the
delayed train or if it should depart on time is called the delay ...

Designing Iron-Amended Biosand Filters for Decentralized Safe Drinking Water Provision
(2012)
There are ongoing efforts to render conventional biosand filters (BSF) more efficient for safe drinking water provision. One promising option is to amend BSF with a reactive layer containing metallic iron (Fe0). The present ...

Impact of Fe0 amendment on methylene blue discoloration by sand columns
(2013)
The influence of metallic iron (Fe0) amendment on the efficiency of sand to discolor a 2.0 mg L-1 methylene blue (MB) solution was investigated in column studies. MB was used as an indicator to identify the optimum Fe0/sand ...
