Tubular settlers and parallel plates improve the settling capacity of circular clarifiers and/or rectangular settling tanks by reducing the vertical distance that flocculated particles must settle before they coalesce to form larger particles.
The tube settler uses multiple tubular channels with an inclination angle of 60° and adjacent to each other. These channels are combined to form a larger effective settling area. This provides a particle settling depth that is significantly less than that of a conventional clarifier, reducing settling time.
The tube settler captures the fine settleable flocs escaping from the clarification zone below the tube settler and allows the larger flocs to move to the tank bottom in a more settleable form. The channels of the inclined tube settler collect the solids into a dense material, promoting the solids to slide down the pipe.

Why use Tube Settler Media?
Tubular settlers provide an inexpensive way to upgrade existing water treatment plant clarifiers and settling tanks to improve performance. They can also reduce the tank capacity/footprint required for new installations or improve the performance of existing sedimentation tanks by reducing solids loading on downstream filters.
Tube settlers are made of lightweight polyvinyl chloride and can be easily supported by minimal structures that usually include sump supports. They are available in a variety of module sizes and pipe lengths to suit any tank geometry, and are custom designed and engineered by the manufacturer.
Advantages of Tubular Settler
The advantages of tubular settlers can be applied to new or existing clarifiers/tanks of any size:
A clarifier/tank equipped with a tubular settler can operate at 2 to 4 times the normal speed of a clarifier/tank without a tubular settler.
It is possible to reduce the coagulant dosage by half while maintaining low incoming water turbidity to the treatment plant filters.
Less filter backwashing equates to significant savings in utility running costs.
New installations using tubular settlers can be designed smaller due to increased flow rates.
The flow rate of an existing water treatment plant can be increased by adding a tubular settler.
Tubular settlers increase the allowable flow rate by expanding the settling capacity and improving the solids removal rate in the settling tank.
