After visiting Honduras on the January trip and seeing the current plants, I decided to work on the sedimentation tank again since there is still a lot to learn about themit. One of our main aspects of the semester was switching to PACl instead of alum. The PACl seemed to be much stickier than alum and we had problems with it sticking to the glass and insides of the flocculator. We also did some experiments switching energy dissipation rates in the jet reverser. We were expecting to find a point where the energy dissipation rate is too high and performance decreased. We didn't find a point where the floc breakup caused a decrease in performance. During these tests we actually found that momentum can play a large role in floc blanket failure because if the momentum of the floc sliding down the incline gets too large it can overpower the pet reverser and cause it to fill up. We also looked at sludge consolidation depending on the depth of the floc hopper. We found that the depth can make a large difference in consolidation.
