2. Subject:Meeting with Janine Pigue of Siemens Water Technology, formerly US Filter, Start:Wed 7/11/2007 9:30 AM End:Wed 7/11/2007 11:30 AM Recurrence:(none) http://www.liqui-cel.com/ http://www.industry.siemens.com/Water/en/ http://www.industry.siemens.com/Water/en/?gkey=[us+filter]&gr=Branded&s=g&WT.src h=1 Us Filter-Interlake 2600 S 17th Ave Broadview, IL 60155 #(708) 345-7672 Broadview Sales person for Siemens Water Technology Janine Pigue #(708) 345-7290 Discuss modifying the system to accommodate Pbar and Booster LCW Systems Upgrade Liqui-cel membrane contactors with higher pressure rating, remove booster pumps

3. Filter for Booster Installation Prototype http://www.shelco.com/pdfs/MH_final.pdf 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

9. 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, 10-30 VDC

10. 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

11. 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
