AguaClara sedimentation tank upflow up flow velocity bellow the plate settlers is 70 m/day
AguaClara sedimentation tank capture velocity 10 m/day
AguaClara sedimentation Area ratio, Velocity Up/Velocity Capture is on the order of 10, ideally we want this ratio to be as high a number as possible
AguaClara currently uses a sedimentation tank plate settler angle of 60 degrees, plate length of 1 meter at 60 degrees, ; plate material is transparent polycarbonate sheets
AguaClara engineer John Erickson has given a very optimistic estimate of 20 years of water plant use for the polycarbonate sheets
John has also stated that the plates that were introduced into the town of Ojojona Honduras's AguaClara plant were constructed of fiberglass and after 2.5 years are already showing significant signs of wear and tear
The next prospective AguaClara plant to be constructed would be in the town of Gracias Honduras.
Gracias plant flow rate of 50 liters/sec
Gracias would have an active sedimentation tank area of 14.026 meters x 2.159 meters per tank, and there would be 3 tanks
