It was determined last semester that the port holes connecting the sections of the tank together should be bigger to eliminate floc break-up. This should be done by Friday, February 9th.
We would like to have the pilot plant operating by Monday, February 11th.
We would like to have preliminary data by Monday, February 18th. This data will be used to compare with data after other adjustments have been implemented.
A flow meter will be installed in the inlet pipe so that we can be sure of the flow rate over time and also accurately test variable flow rates.

Currently, sampling takes place in three adjustable locations within the tank. Before analysis in the turbidity meter, the water enters a long glass tube which is meant to act as a "miniature sedimentation tank". However, previous testing has indicated that a significant amount of floc reached the turbidimeters. We would like to improve the method of sedimentation before the water gets to the turbidimeter. We will try to do this by adding insulation to the exposed tubing by Monday, February 18th.
We will have comparitive data of the before and after adding insulation by Monday, February 25th. During this period at the beginning of the semester, we will also be working on design details of the sedimentation tank. During this time, we would also like to implement better lighting in the plant, and develop more detailed procedure for quantifying floc size in various parts of the sedimentation tank.
A main goal of the testing is to develop a profile of floc formation along the length of the large-scale tapered flocculator.
