Operating principle
TFB elements can use cloth or metal/polymer sintered media. Solids leave with the concentrated slurry, allowing a smaller discharge valve. Tighter element spacing than a typical TFA arrangement provides more filtration area in the same vessel size.
The dual-manifold design is central to continuous operation. One manifold transfers filtrate; the second regenerates or precoats a selected branch while the remaining branches stay online.
Workflow
- Fill the vessel with feed.
- Precoat when required, or start with a suitably rated cloth.
- Transfer filtrate through the active manifold branches.
- Regenerate branches sequentially according to cake thickness, flow, differential pressure or time.
- Open the bottom valve when the concentrated slurry reaches the discharge condition.
The achievable concentration and continuity depend on solids loading, particles, regeneration and downstream slurry handling, and should be validated with the actual material.
