For the fall semester, the Rapid Mix Contact Chamber team continued last semester's work in improving the efficiency worked on assessing the utility of the contact chamber performance in the rapid mixing of raw water and coagulant. The goal of the team was to determine the utility of contact chamber by team determined this performing the tests with and without the contact chamber using the coagulant properties which were found. The team ran different tests with a straight flocculator to find the relationship between headloss head loss and nanocluster nano cluster buildup and to measure the difference in the headloss head loss values when the tests were run with and without the contact chamber. The team found that there was no significant reduction in the deposition of nanoclusters on the flocculator walls on effect on adding a contact chamber unit to for the apparatusflocculator studied.
