1. Prepare Tools and Materials for Cleaning the Backwash Filter:

2. Power Off and Depressurize:

Ensure the power to the backwash filter is off, and release all internal pressure.

3. Disassemble the Filter Screen and Filter Layers:

Depending on the structure of the filter screen (for multi-layer screens, disassemble layer by layer), use appropriate tools to safely remove the filter screen and filter layers.
Handle with care during disassembly to avoid damaging the filter screen or other components.

4. Clean the Filter Screen and Filter Layers:

For the filter screen, use a high-pressure water jet or a soft brush along with a cleaning agent to thoroughly remove accumulated dirt and debris.
For the filter layers (e.g., sand or gravel media), rinse repeatedly with clean water and use a vacuum if necessary to remove any remaining residue.

5. Inspect and Replace the Filter Screen:

After cleaning, inspect the filter screen for any damage or deformation to ensure it is in good condition.
If any damage to the filter screen or significant media loss is found, replace it with a new filter screen or media promptly.

6. Reinstall the Filter Screen and Filter Layers:

Reinstall the cleaned filter screen and filter layers in their original positions.
Check all connections to ensure they are secure and leak-free, then restore power and resume operation.

7. Record Cleaning Information:

Document each cleaning session, including the date, cleaning medium used, and its concentration, to facilitate future reference and optimize the cleaning procedure.

Precautions:

Avoid directly spraying any chemical solvents onto the filter screen during cleaning to prevent damage to the filter media.
Use caution with the pressure of the water jet or brush to avoid unnecessary damage.
Regularly check the sealing performance of the backwash filter to ensure there are no leaks.
Adjust the cleaning frequency and intensity based on actual operating conditions to achieve optimal cleaning results.
