What is the maximum percentage of backwash water that should be used for dual media filters?

For dual media filters, the maximum percentage of backwash water that should be used is 6%. This guideline is established to ensure the efficiency and effectiveness of the filtration process. Using an appropriate amount of backwash water is crucial to remove accumulated debris and particles without disturbing the filter media layers or causing excessive wear.

Backwash is a process that helps to maintain the performance of the filter by flushing out trapped particles. If too much backwash water is used, it can lead to a significant loss of filter media and may result in poor filtration performance. Maintaining the backwash water percentage at the recommended level ensures that the filter operates optimally while preventing media loss and maintaining the structural integrity of the filter bed. Thus, adhering to the 6% maximum for dual media filters supports effective water treatment processes and promotes longevity of the filtration system.
