Future Challenges
* Completion of the study on the effects of various alum dosages and flocculator length
During fall 2009, we began to run experiments for challenge 2. Though a lot of data have been retrieved, this challenge has yet been completed. A speculative conclusion has been made based on the results gathered so far during fall 2009; however, for precision and more data, this challenge needs to be continued. The completion of this challenge will be the first goal for the Spring 2010 Tube Floc team.
* Start on challenge 3
For the next challenge, the effects of PH variation will be studied. Floc strength is closely related to the influent PH and alum; by studying the optimal influent PH and effects of PH in different situations, we expect to find essential information that can facilitate in the improvement of the AguaClara flocculator.
