    Making Fe0-Based Filters a Universal Solution for Safe Drinking Water Provision
    (MDPI, 2017-07-12) Naseri, Elham; Ndé-Tchoupé, Arnaud; Mwakabona, Hezron; Nanseu-Njiki, Charles; Noubactep, Péguy; Njau, Karoli; Wydra, Kerstin
    Metallic iron (Fe0)-based filtration systems have the potential to significantly contribute to the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) of substantially improving the human condition by 2030 through the provision of clean water. Recent knowledge on Fe0-based safe drinking water filters is addressed herein. They are categorized into two types: Household and community filters. Design criteria are recalled and operational details are given. Scientists are invited to co-develop knowledge enabling the exploitation of the great potential of Fe0 filters for sustainable safe drinking water provision (and sanitation).

    Metallic iron for safe drinking water provision: Considering a lost knowledge
    (Pergamon, 2017-06-15) Mwakabona, Hezron; Ndé-Tchoupé, Arnaud; Njau, Karoli; Noubactep, Chicgoua; Wydra, Kerstin
    Around year 1890, the technology of using metallic iron (Fe0) for safe drinking water provision was already established in Europe. The science and technology to manufacture suitable Fe0 materials were known and further developed in this period. Scientists had then developed skills to (i) explore the suitability of individual Fe0 materials (e.g. iron filling, sponge iron) for selected applications, and (ii) establish treatment processes for households and water treatment plants. The recent (1990) discovery of Fe0 as reactive agent for environmental remediation and water treatment has not yet considered this ancient knowledge. In the present work, some key aspects of the ancient knowledge are presented together with some contemporised interpretations, in an attempt to demonstrate the scientific truth contained therein. It appears that the ancient knowledge is an independent validation of the scientific concept that in water treatment (Fe0/H2O system) Fe0 materials are generators of contaminant collectors.
