Tube settler and parallel plates increase the settling capacity of circular clarifiers and/or rectangular sedimentation basins by reducing the vertical distance a floc particle mustsettle before agglomerating to form larger particles.
Tube settlers use multiple tubular channels sloped at an angle of 60° and adjacent to eachother, which combine to form an increased effectivesettling area. This provides for a particle settling depththat is significantly less than the settling depth of aconventional clarifier, reducing settling times
1. Clarifiers/basins equipped with tube settlers can operate at 2 to 4 times the normal rate of clarifiers/basins without tube settlers.
2. New installations using tube settlers can be designed smaller because of increased flow capability.
3. Flow of existing water treatment plants can be increased through the addition of tube settlers.
4. Tube settlers increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
