Metallic iron for water treatment: A knowledge system challenges mainstream science
A knowledge system (KS) is a knowledge that is unique to a given group of persons. This form of knowledge may have a local or natural origin and is linked to the community that has produced it. On the contrary, the core ... -
Metallic iron for water treatment: Healing a research community
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 ... -
MODELING AND SIMULATION OF IRON/SAND FILTERS
This article develops a mathematical model of Iron (Fe0) /sand filter taking into account the loss of porosity during the filtration process. The mass transport advection-dispersion equation is derived to predict, through ... -
On the mechanism of microbe inactivation by metallic iron
This letter challenges the concept that the metallic iron (Fe0) surface contributes directly to the process of micro-organism inactivation in aqueous solutions. It is shown that any antimicrobial properties of Fe0 is related ... -
On the operating mode of bimetallic systems for environmental remediation
This letter challenges the concept that Fe0/Me0 bimetallic systems enhance contaminant reduction on Me0 surfaces. It is shown on a pure thermodynamic perspective that any enhancement of contaminant reduction by Fe0 in the ... -
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 ... -
On the validity of specific rate constants (kSA) in Fe0/H2O systems
The validity of the specific reaction rate constants (kSA) in modelling contaminant removal in Fe0/H2O systems is questioned. It is shown that the current kSA-model does not consider the large reactive surface area provided ... -
Optimising the Design of Fe0-Based Filtration Systems for Water Treatment: The Suitability of Porous Iron Composites
Rahman, Mohammad Azizur; Karmakar, Shyamal; Salama, Heba; Gactha-Bandjun, Nadège; Btatkeu, Brice Donald; Noubactep, Chicgoua(Journal of Applied Solution Chemistry and Modeling, 2013-08-31)
This study assessed the functionality of metallic iron (Fe0) filtration systems using porous iron composite (PIC) as an alternative to granular Fe0/aggregate mixtures. The usage of PIC for water treatment has many challenges ... -
Predicting the Hydraulic Conductivity of Metallic Iron Filters: Modeling Gone Astray
Since its introduction about 25 years ago, metallic iron (Fe0) has shown its potential as the key component of reactive filtration systems for contaminant removal in polluted waters. Technical applications of such systems ... -
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ... -
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ... -
Rescuing Fe0 remediation research from its systemic flaws
The well-accepted assumption of metallic iron (Fe0) acting as electron donor for environmental remediation has created an unstable domain of knowledge for the past 23 years. This assumption is discouraging some outstanding ... -
Testing Metallic Iron Filtration Systems for Decentralized Water Treatment at Pilot Scale
Tepong-Tsindé, Raoul; Crane, Richard; Noubactep, Chicgoua; Nassi, Achille; Ruppert, Hans (Water, 2015)
There are many factors to consider for the design of appropriate water treatment systems including: cost, the concentration and type of biological and/or chemical contamination, concentration limits at which contaminant(s) ...
