What is tube settler

Tube settlers, also called lamella clarifiers, are used to remove solids in wastewater treatment. Tube settlers use multiple tubular channels sloped at an angle of 60° and adjacent to each other, This design multiplies the sedimentation area up to 15 times per square meter surface area and helps to improve sedimentation in water and wastewater treatment plants.

Tube settler & Lamella is a very significant unit of clarifiers in the water and wastewater treatment plant. Tube settler & Lamella improves effluent water quality and results in a significent decrement in plant costs. Lamella is usually made of PP and PVC.

How does tube settler work?

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.
Tube settlers offer an inexpensive method of upgrading existing water treatment plant clarifiers and sedimentation basins to improve performance. They can also reduce the tankage/footprint required in new installations or improve the performance of existing settling basins by reducing the solids loading on downstream filters.
