Application of Carbon Dioxide Treatment to Manage Scale in Building Potable Water Systems

The U.S. Army Construction Engineering Research Laboratory (USACERL) has developed a carbon dioxide treatment system to remove scale from potable water systems safely and effectively. This report describes laboratory experiments to optimize the system and presents the results of field demonstration at three sites. Carbon dioxide treatment will also be demonstrated in a dormitory at a university campus; preliminary laboratory work for that project is described. Information is provided to help installation Directorates of Engineering and Housing (DEHs) test their water supplies and determine the potential for scaling. In addition, generic guidance is presented to assist the DEH in installing, operating, and monitor a carbon dioxide treatment system.
