Can the upflow velocity in the AguaClara sedimentation tank be significantly (factor of 2 to 10) increased without degrading performance? Can sloped plates or tubes help to stabilize a floc blanket at high upflow velocities? Can flocs be transported to a floc hopper when there are high upflow velocities in the sedimentation tank? What geometry is required for this new high rate sedimentation tank? - How do the plate settlers with a capture velocity of 1 mm/s connect to the plate settlers with a capture velocity of 0.12 mm/s?
