HeliThickener: A Game Changer in Sludge Dewatering & Environmental Treatment
In the realm of environmental and water treatment, sludge management is a crucial yet often complex aspect. One key technology used for sludge dewatering is the HeliThickener, a revolutionary innovation that offers substantial advantages over traditional methods.
The HeliThickener: A Unique Approach to Sludge Dewatering
The HeliThickener is a type of centrifugal thickener that utilizes a unique helical screw conveyor to dewater sludge. This "interrupted flight screw conveyor," developed by Walker Process Equipment, is the defining characteristic of the HeliThickener and sets it apart from other thickeners.
Interrupted Flight Screw Conveyor: A Closer Look
The interrupted flight screw conveyor consists of a helical screw with gaps between the flights, allowing for the passage of water and solid sludge particles. The conveyor's rotation creates a centrifugal force that pushes water outwards, while the interrupted flights allow solid particles to settle and move towards the center. This continuous process results in a concentrated sludge cake, while the clarified water is discharged.
Advantages of the HeliThickener:
- High Dewatering Efficiency: The HeliThickener boasts exceptional dewatering efficiency, yielding a significantly higher solids content in the final sludge cake compared to traditional gravity thickeners.
