During the Spring 2009 semester I have been the team leader of the Dissolved Air Flotation of Flocs Team. This semester the Floating Floc team broke into two sub-sub teams: Floating Floc Aeration Method and the Floating Floc Sand Filter Fluidized Bed Method. I am working with the aeration group which is focused on the use of aeration of the water in the grit chamber to reduce the dissolved oxygen (DO) content of the water. Thus far I have worked hard to solve the problems we have encountered in the design and operation of the mini grit chamber/entrance pipe and at this point Tanya and I have come very close to solving all of the problems (hopefully). The experiments we have performed have not had the results that we had hoped for, but it is possible that problem actually lies in the testing DO probe being under different pressures rather than the concept in general.
