Subject:Meeting with Janine Pigue of Siemens Water Technology, formerly US Filter, Start:Wed 7/11/2007 9:30 AM End:Wed 7/11/ :30 AM Recurrence:(none) h=1 Us Filter-Interlake 2600 S 17th Ave Broadview, IL #(708) Broadview Sales person for Siemens Water Technology Janine Pigue #(708) Discuss modifying the system to accommodate Pbar and Booster LCW Systems Upgrade Liqui-cel membrane contactors with higher pressure rating, remove booster pumps

Filter for Booster Installation Prototype Pleated polypropylene media cartridge –0.5 micron, 90% efficiency rating –Over 5-1/2 square feet of media, very high dirt holding capacity than other cartridges. –$24 each Pressure drop vs GPM at 0.5 micron –At 2 GPM, delta P at less than 1 PSID –Recommended Changeout 25 PSID

Filter Monitoring Tap on Filter housing for inlet and outlet pressure monitoring Local pressure gauges Remote Pressure Transducers, –0.5% of full scale accuracy –4-20 mA output signal –Remote monitoring from Main Control Room Acknowledgement to Kent Triplett, –Sensor testing and verification –Loop Power Source, VDC

Alarm Set Point Filter Delta P Clean, at 1 GPM, 0.3 PSID Corrector needs 80 PSID for 0.6 GPM Booster 95 LCW System provides S=120 PSID min

Bottom Line Installing Small Filter in Enclosure will teach us : –Impact on New Corrector Program –Health of the Booster 95 LCW System –Protect prototype corrector during critical testing
