Like lamella clarifier, tube settlers use multiple tubular channels sloped at an angle of 50° to 60° and adjacent to each other, which combine to form an increased effective settling area. This provides for a particle settling depth that is significantly less than the settling depth of a conventional clarifier, reducing settling times. Material of construction for tubes is PVC, which is light weight. It con be supported on structures. Tubes are available in different sizes which gives it more flexibility to fit in any type of tank.
