Tube settlers, also called lamella clarifiers, are used to remove solids in the waste water treatment.tube settlers are single plastic profiles combined to tubes. This design multiplies the sedimentation area up to 15 times per square meter surface area and helps to improve sedimentation in water and waste water treatment plants.Different executions support a better process and cost reduction of the plant.

Tube settlers increase the settling capacity of circular clarifiers and/or rectangular sedimentation basins by reducing the vertical distance a floc particle must settle before agglomerating to form larger particles. The settlers use multiple tubular channels sloped at an angle of 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. Tube settlers capture the settleable fine floc that escapes the clarification zone beneath the tube settlers and allows the larger floc to travel to the tank bottom in a more settleable form. The settler's channel collects solids into a compact mass which promotes the solids to slide down the tube Channel.

The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size: Clarifiers/basins equipped with tube//lamella settlers can operate at 4 to 8 times the normal rate of clarifiers/basins without tube or lamella settlers. It is possible to cut coagulant dosage by up to half while maintaining a lower influent turbidity to the treatment plant filters. Less filter backwashing equates to significant operating cost savings for both water and electricity. New installations using tube can be designed smaller because of increased flow capability. Flow of existing water treatment plants can be increased through the addition of tube or lamella settlers. Tube increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
