This powerpoint presentation begins by providing an evaluation of mobile point of entry (POE) and point of use (POU) systems, and an evaluation of mobile water treatment. The Expeditionary Unit Water Purifier (EUWP), a mobile water treatment system designed by the Department of Defense using military water quality specs is presented, along with field testing results from Gallup, New Mexico; Lake St. Clair, Michigan; and, Port Hueneme, California. Conclusions were that: EUWP field deployment for pathogen reduction needs to operate withpre-chem, UF, RO, and post-disinfectant providing multiple treatmentbarriers to maximize removal;2nd-pass RO component was not evaluated in these studies and mayalso provide additional removal capability;EUWP UF nylon O-rings may be replaced with Noryl type to reducewarping;Operational issues need reassessment: cleaning/backwashing,determination of DIT (psi/min) control limit for removing UF modulesfrom service;EUWP study reports expected in Autumn of 2008; and,SWTR-LT2 MF/UF pathogen challenge testing will be most practicalusing modules that incorporate full-scale housing, end cap, sealdesign components. Otherwise, problems may not be apparent until inthe field. Includes tables, figures.
