Auto backwash filters utilise a special filtration medium that traps impurities as water flows through the system. When the filter becomes clogged or a pre-set pressure difference is achieved, the backwashing cycle is triggered automatically. During the cycle:
- Reverse Flow: The trapped debris is flushed from the filtration medium by utilising water or air.
- Self-Cleaning Mechanism: The system releases contaminants through a drain valve without disrupting the operation.
- Automation: Backwashing can be initiated on a time basis, pressure differential, or other conditions for maximum performance and minimal maintenance.
Some systems, like bead filters, retain biofilm under backwashing to supply biological filtration along with mechanical filtration. Pairing complete monitoring systems with auto backwash filters allows you to automate performance optimization. These systems monitor filter efficiency and trigger backwashing cycles as required, ensuring uninterrupted operation and superior water quality.
