(while applying an alum dose of 20 mg/L)
Plant Entrance Tank: pH = 6.77
Plant Exit Tank: pH = 6.50
*Carlos, the opperatoroperator, will continue taking pH data
every day for a week.
...
*We know the pH in some of the tanks.
*Once I have all of the numbers I can see if the problem can be modeled using water chemistry.
*These numbers may be the key to solving the problem!
*John also suggested that maybe the turblance turbulence at the entrance tank caused by the high flowrate flow rate could put more air bubbles in the system that then bring up floc in the sed tank.

- John and Tamar are having issues finding something to measure the temperature of the water as it enters the plant as well as when it leaves for the distribution tank.
*I am not sure yet if the pH of the influent was taken before or after the alum was added. It is important that the the water tested does not have alum in it so that the difference can be analyzed.
