Abstract Cellulose filters were dipped and padded with m ‐aramid dissolved in N , N ‐dimethylacetamide followed by coagulation in distilled water. The coated filters were then chlorinated in a hypochlorite solution. The liquid permeability of the m ‐aramid‐coated cellulose filters was examined. The resulting chlorinated and unchlorinated filters were assessed for their ability to disinfect contaminated water. The chlorinated m ‐aramid‐coated cellulose filter produced 5 log reductions of Escherichia coli and Staphylococcus aureus , which was much higher than that observed on the unchlorinated m ‐aramid‐coated cellulose filter. © 2013 Wiley Periodicals, Inc.
