Sand washing for circulating water filters
Thread Content
How to shut down and clean the graded sand and gravel in the circulating water filter? Is there any procedure for this?
What type of filter do you use? We have filters that can be cleaned without shutting down operations; feel free to call for more details
We have self-cleaning filters that don’t need to be cleaned.
When the filter pressure difference reaches the target value, it is switched off, and backwashing is performed via the backwashing line from the filter outlet back into the wastewater pipeline.
For the friends on the fourth floor, is backwashing done continuously? Does it not need to be taken apart for cleaning?
There is no need to disassemble it for cleaning; it’s automatic.
It can be used for about 3 years; after that, the sand inside needs to be replaced.
