Techniques

Chapter 1: Techniques

Dewatering with Roepress Technology

Roepress technology, synonymous with Roediger Pittsburgh's belt filter presses, utilizes a sophisticated dewatering technique based on vacuum filtration. This technique relies on a series of belts, supported by rollers and a pressure-applying system, to effectively separate solids from liquids.

The process involves the following steps:

1. Slurry Feeding: The slurry to be dewatered is fed onto the filter belt, which is typically made of synthetic material like polyester or polypropylene.
2. Vacuum Application: A vacuum system draws liquid through the filter media, creating a pressure differential that drives the dewatering process.
3. Filtration and Cake Formation: As liquid passes through the filter media, the solid particles are retained, forming a concentrated cake on the belt surface.
4. Belt Movement and Cake Discharge: The belt continuously moves through the press, transporting the formed cake towards a discharge point.
5. Cake Washing (Optional): In certain applications, a washing stage can be incorporated to further reduce the liquid content and improve cake purity.
6. Cake Discharge: The dewatered cake is discharged from the belt, ready for further processing or disposal.

Roepress technology offers several advantages over traditional dewatering techniques:

• High Efficiency: The vacuum filtration process achieves high levels of cake dryness, minimizing liquid discharge and maximizing solid recovery.
• Continuous Operation: Belt filter presses operate continuously, ensuring a steady flow of dewatered solids and consistent processing.
• Versatile Application: Roepress systems can handle a wide range of slurries with varying viscosities and solids content.
• Minimal Footprint: Compact design allows for space-saving installation in various industrial settings.
