| Conventional cake filtration | Recessed chamber | Compare chamber volume, filter media and the complete operating cycle. |
| Additional cake compression | Membrane | Check whether tests show a useful benefit from squeezing, and confirm the plate and pressure ratings. |
| A pressure-sensitive duty | High-pressure configuration | Evaluate the material response and the ratings of the plates, frame, pump and accessories together. |
| Less manual cake handling | Quick opening / vibrating | Review non-filtration time and discharge behavior; automation does not make the filtration cycle continuous. |
| Testing before scale-up | Laboratory | Use a representative sample and account for differences between the test and the production duty. |
