Floating Floc Team Goals for Summer 2009

SETTING UP

Modify Experimental System to Develop Consistent Supersaturation in Inflow Water
Changes were made to the sand filter experimental system in order to establish more consistent supersaturation of the influent water into the sand filter. The existing aerator was replaced by a taller aerator that would allow for increased residence time of the bubbles.
*June 8-11: Aerator was incorporated into the new system and leaks were fixed. Adela, Shaina, Tanya
*June 10-11: The water source of the system was changed from tap water to the white tub in the lab to allow for the removal of the hot and cold water valves. The cold and hot water valves were replaced with a flow control valve after the aerator and a water wasting valve was added to the aerator for better water level control. Adela, Shaina, Tanya
*June 11: Process controller methods for the experimental system were rewritten. (Reviewed with Shaina) Adela, Tanya
June 14 - June 20: Debug experimental system, debug process controller methods, and properly configure the system (determine set points for minimum and maximum water levels, etc). Adela, Shaina, Tanya
*June 20 - June 24: Verify that the new aerator functions properly and olds results are replicable. Adela, Shaina, Tanya
