Introduction
This semester, the pilot plant sedimentation team is experimenting with the parallel sedimentation tanks to get closer to the goal of 1 NTU water. Because the two tanks are identical, experiments now have a control, and the effluent differences cannot only be attributed to the turbidity of the inlet water or alum concentration changes. While leaving a sludge blanket in the control, experiments will be performed on the other sedimentation tank to see how effectively lamella and sludge blankets can interact. Some of the experiments include determining if there is minimum required tank depth below the lamella for blanket formation, dimensions of the lamella themselves, and spacing between lamella. Each of these experiments will be performed at various upflow velocities, since the plant flow rate in Honduras is also variable.
The chief research goals this semester were:
