AWWA WQTC58929

The increased demand for water in the front range of Colorado, coupledwith variations in source water quality, has prompted the City of Thornton,Colorado, to expand the existing Columbine Water Treatment Plant from a 28-MGD conventional treatment plant to a 45-MGD microfiltration (MF) and reverseosmosis. To determine which microfiltration membrane system is best suited totreat this source water, several membrane manufacturers were solicited toparticipate in a pilot study. Characterization of the filtrate water was performedfrom a turbidity and particle counting perspective and the integrity of each of thepilot systems was tested with direct and indirect test methods.The purpose of this study was to determine the detection limit for amembrane integrity failure on each pilot membrane system using both direct andindirect integrity test methods. In addition, the different issues associated withproper sampling and interference removal for each system were addressed. Thisprovided the opportunity to apply both existing and new indirect monitoringtechnologies including particle counting, laser turbidity, and multiplexed lightscattering. Includes 8 references, tables, figures.
