Pilot Plant Meeting Minutes

Spring 2009 Minutes

April 17, 2009

Working Group: 1

Accomplishments
  • Replaced tubing through peristaltic pump with size 13 tubing to dose PAC more accurately
  • Fixed loose wiring in fourth turbidimeter so it registers in Process Controller
  • Plant is fully operational
  • Tested configuration 1 (1st channel baffle spacing: .051 m, 2nd channel baffle spacing: .051 m)
Outcomes
  • Testing for configuration 1 was ineffective as raw water turbidity was >2 NTU.
Issues
  • Water has been coming in very clean, with turbidities >2 NTU. Dosing is having minimal, if any, effect.
  • Turbidimeter 2 is constantly fogging up on the outside of the sampling vial. Inside the chamber is hot and it smells like burning. We have disabled the turbidimeter until we can take it apart and see if there is a noticeable problem. If we cannot find anything we will do without this turbidimeter and make due with raw water turbidity and two turbidimeters.
  • Are running out of time to complete all configuration profiles before Wiki Report is due. As resolution we completed a counterproposal to extend the due date for submission to Monroe.
