* Kellie got to the plant on Monday, to find that the flow rate was only 3 gal/min. Although the alum was pumping al 20mg/L, it did not appear to be overdosing (no white fluffy flocs). At the Pilot Plant meeting on Thursday, we were notified that the alum has not been pumping, because somehow the tube got dislodged from the pump.
* Still no sludge blanket in either tank!
* With the colder weather we are having, the ideal alum dose is uncertain, since Tom says that you're supposed to DECREASE the alum when the temperature decreases (not increase - there has been some confusion).
* The previous data was invalid, since Shaina found our pump to not be working correctly.
* The trough that is located in the flocculator that helps control the level of water in the tank is slanted and has been that way since we inherited the plant at the beginning of the semester.
