Abstract

ABSTRACT The antimicrobial activity of a new cross-linked N -halamine polymer against bacteria and viruses was evaluated. The polymer achieved a 9-log 10 reduction of bacteria (both Escherichia coli and Staphylococcus aureus ) in 1.5 h and a 5-log 10 reduction of bacteriophage PRD1 in 3 h. At the same time, the ability of the nonhalogenated polymer to trap halide ions was examined. The polymer was incorporated into a multifiltration system to study the ability to produce water free of bacteria, viruses, and halide ions. The antimicrobial activity, useful lifetime, halide ion level, and recycling possibilities of the system were quantified on a laboratory scale. A design for a large-scale multifiltration system based on this polymer is proposed.
