Bactericidal Efficacy of a Personal Water Purification Straw

Abstract

The straw was designed to provide easy to carry, portable water purification to soldiers in the field. The purification process takes place in a single pass while drinking water through the straw. The purification system incorporates a multistage process consisting of a iodinated (I-5) resin, a one-micron filter and an absorption system used for pH corrections and removal of iodine residual that could affect taste. The straws were evaluated for the removal of Klebsiella terragena bacteria in general non-challenging and challenging test waters at pH 5, 7 and 9 and at 5 degrees centigrade and 25 degrees centigrade, according to EPA guidelines.
