Designing the cleaning system — suction-scanner, backflush or brush mechanisms that clear the screen online with minimal water loss.
Self-Cleaning Filter Design — in depth
The cleaning mechanism defines the “self-cleaning” performance. We design the right approach — a traversing suction scanner, a focused backflush, or a brush/rake — triggered by differential pressure or timer, to clear the screen online with the least purge water and no process interruption.
What matters in practice
Vacuums debris off the screen in place.
Reverse flow focused on a screen segment.
Mechanical clearing for sticky solids.
Cleaning on pressure rise or schedule.
| Method | Purge loss | Best for |
|---|---|---|
| Suction scanner | Low | General duty |
| Backflush | Medium | Fine screens |
| Brush | Low | Sticky solids |
| Trigger | dP or timer | Automatic |
