Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>A series of experiments were performed to investigate the removal of viable bacteria [<italic>Escherichia coli</italic>, total coliforms and standard plate count (SPC) bacteria] in lake water by denim filtration. Filtration with indigo reagent‐dyed denim physically removed <italic>E. coli</italic> (up to 95%) and total coliforms (up to 92%) from lake water. The removal efficiencies of SPC bacteria (up to 85%) were generally lower than those of <italic>E. coli</italic> and total coliforms. The adsorption of bacteria to particulate matter larger than the effective pore size of the denim (ca. 48 μm) and the subsequent physical sieving of the large particulate matter seemed to be the dominant disinfection mechanism.</p> </abstract>
