Tube Settlers

Tube Settlers

    Product Information

    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.

    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 tube settler’s channel collects solids into a compact mass which promotes the solids to slide down the tube channel.

    Made of lightweight PVC, tube settlers can be easily supported with minimal structures that often incorporate the effluent trough supports.

    The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size

    • Minimise turbidity load on filters
    • Cut coagulant dosages by up to half
    • Multiple tubular channels sloped at an angle of 60°
    • Flame-resistant, self-extinguishing PVC that is also inert to naturally occurring constituents in water and wastewater
    • Tested and certified by NSF to ANSI/NSF Standard 61

    Technical specs
