The values used to run the experiment were as follows. We chose to use 9.336 mg/L of calcium hypochlorite for this lab experiment because it is half way between 12201 mg/L and 6470 mg/L, which were the average concentrations used at Tamara and 4 Communidades (The towns with the most severe issues with flow rate). The flow rate would be run at 64 68 mL/min, because it is the average of the reported range of flow rates in Honduras (48 mL/min-80mL/min).
Procedure
15 mL of deionized water would be put into the 5 gallon stock tank. 158 mL of Calcium Hypochlorite powder would be added to this stock tank. 2 L of deionized water would be added on top of this in the stock tank. The carboy being used would then be simply stirred and shaken for 5 minutes in order to mix the solution thoroughly. The tank would be allowed to settle for 10 minutes, and then the experiment would be run. The 7kPa sensor would be set up using Easy Data and the "cm of water" calibration file. The pH meter would be run using the program pH Meter.
Results
Using the flow rate of 68 mL/min, the model (assuming no restricted flow) would require approximately 4 hours and 9 minutes to be emptied (4.16 hours).
