Results and Discussion
During fall 2009, two challenges were tested with the completion of one. For the first challenge, the study of the effect of shear rate on tube flocculator performance, our goal was to replicate an experiment from spring 2009 for the team to familiarize itself to the experimental apparatus and analysis techniques. Though this challenge did not provide new data, it showed the overall functions of the tube floc experimental setup and the computer programs used for data analysis.
Though the second challenge, the effect of alum dose and flocculator length on tube flocculator performance, is yet to be completed, significant progress has been made and much data has been studied to enable us to come to a speculative conclusion. We will continue to work on this challenge to confirm the conclusion we have drawn so far and to acquire more information.
