BACKGROUND ________________ The City of Crested Butte processes Coal Creek water from two existing conventional treatment sites under the authority of the Crested Butte Water Treatment Plant. The conventional treatment utilizes coagulation, flocculation, sedimentation and mixed media filtration. The exiting conventional treatment plant produces enough potable water to meet demands with favorable raw water conditions. However, future expansion of the service area will require a modification of the current water treatment system. One proposed solution is the implementation of membrane technology The City of Crested Butte is interested in evaluating the Pall Microfiltation (MF) system for the design on a proposed 2-MGD expansion of the Crested Butte water treatment plant (WTP). The Pall Microfiltration system was selected for pilot testing as a viable membrane technology. The Pall pilot test started on March 31, 2001 and ended on July 7, 2001. Operating and performance data from the Pall pilot and test results from the City of Crested Butte and Sear Brown were collected and presented in this report. TEST EQUIPMENT & OPERATION: _____________________________________ A fully automated pilot system was installed at the City of Crested Butte WTP test site. The process flow diagram is shown in Figure I. The system was equipped with one Pall Microza MF membrane with the physical characteristics described in Table I.
