An alternative concept stipulates that contaminants are removed by adsorption, co-precipitation and size-exclusion in a reactive filtration process. This article underlines the universal validity of the alternative concept. It is shown that admixing non-expansive material to Fe0 as a pre-requisite for sustainable Fe0-based filtration systems. Fe0-based filters are demonstrated an affordable, appropriate and efficient decentralized water treatment technology. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6693 %~ FID GEO-LEO e-docs
