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 "Modifications to Test Procedure" 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 Procedure" 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.
