Air-burst cleaning — pulses of compressed air fired back through the screen to shock off accumulated debris, silt and biofilm, keeping passive and traveling intake screens clear without interrupting supply.
Intake Screening for Water & Desalination Plants
Air-burst (air-backwash) cleaning periodically fires a charge of compressed air back through the screen from the inside, violently dislodging debris, silt and biofilm from the slots. It is the standard active cleaning method for passive cylindrical screens — wedge-wire, T-screens and pods — and is often retrofitted to traveling screens facing heavy biofouling or sediment loads.
Pulsed reverse-air cleaning
A charged receiver dumps a rapid air pulse through the screen.
Timed or differential-pressure-triggered bursts on a schedule.
Directs the pulse evenly across cylinders or panels.
Sequences bursts and integrates with the intake SCADA.
Added to existing passive or traveling screens.
Mechanical shock plus dosing controls stubborn biofouling.
| Parameter | Typical | Notes |
|---|---|---|
| Trigger | Timer or ΔP | Scheduled or on demand |
| Action | Reverse air pulse | From inside the screen |
| Removes | Debris, silt, biofilm | Restores slot open area |
| Supply | Stays online | No flow interruption |
| Fit | New or retrofit | Passive & traveling screens |
