Product Description
Tube / Plate/ Lamella settlers are modern unconventional solid - liquid separation systems units. These settling units due to higher settling area and effective arrangement of multiple tubular channels sloped at an angle of 55°- 60° and adjacent to each other, increases the rate of settling. These modern settlers provides 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.
Why Tube Settlers ?
The Tube settler contains inert, non corrosive UV resistant PVC inert media placed in inclined manner and arranged in structured manner with its self interlocking system. The smooth surface ,inclined arrangement and adequately designed void space helps large solids, flocs and particulate matter the move downwards of the settler. The tube setters has sharp conical bottom which enables to effective setting and reduces footprint. Due to such arrangement the extra mechanical scrapping arrangement which is usually and integral part of conventional clarifier is not required. This also provides benefit of choice of geometry of settling unit which is very essential during space planning of compact systems. The tube 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. Made of lightweight PVC, tube settlers can be easily supported with minimal structures that often incorporate the effluent trough supports. They are available in a variety of module sizes and tube lengths to fit any tank geometry, with custom design and engineering offered by the manufacturer.
Advantages of Tube Settlers
The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size:
- Clarifiers/basins equipped with tube settlers can operate at 2 to 4 times the normal rate of clarifiers/basins without tube settlers.
- It is possible to cut/ reduce coagulant dosage by up to half while maintaining a lower influent turbidity to the treatment plant filters.
- Saves electricity as no mechanical and rotating equipment's it also lowers Operational Expenditure(OPEX).
- Less filter backwashing of downstream units equates to significant operating cost savings for both water and electricity.
- New installations using tube settlers can be designed smaller because of increased flow capability.
- Flow of existing water treatment plants can be increased through the addition of tube settlers.
- Tube settlers increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
- Extended life of unit as no mechanical or rotating units are involved.
- Inert PVC material has very long life and can be replaced or top-uped easily.
