One of the concerns that we had with the data from previous semesters is that the tube settlers might not be a good approximation of AguaClara's standard sedimentation tanks. In order to verify the data from the tube settlers, I designed a grab sample procedure. The calculations for this procedure can be found here under the heading"Jar Test Turbidity Sampling" Modifications to Test Procedurewhich is under "Testing Set-Up Modifications" section. The data from this procedure will be compared to the data from the turbidimeters to verify the validity of our testing procedures.
Also, I looked into data analysis techniques that I will use to analyze the data from the plant. The information on these programs and how I intend to use them can be found here under the "Data Analysis ProcedureTechniques" section. Unfortunately, due to the many changes that we made in plant set-up, we have not yet collected data. Most recently, overflow from the automatic flow control device has prevented data collection. I am excited to analyze data starting the week after Spring Break to observe the effects of the improvements we have made to the flocculator.
