Which process is used to maintain clean filters in pools?

Backwashing is the correct process used to maintain clean filters in pools. This technique is essential for ensuring that the pool's filtration system operates efficiently. During backwashing, water is temporarily reversed through the filter to dislodge and flush out the debris and contaminants that have accumulated in the filter media. This process helps maintain optimal water clarity and circulation by preventing clogs that could reduce the filter's effectiveness.

While filtration is the overall process of removing impurities from the pool water, it does not address the cleaning of the filters themselves. Disinfection and super chlorination are methods aimed at sanitizing pool water by killing bacteria and controlling algae growth, but they do not serve to clean the filters. Backwashing specifically targets the maintenance of the filter, making it an essential practice for proper pool operation and ensuring a clean swimming environment.
