Mudball formation, filter media cracks, or shrinkage are generally due to what?

High turbidity levels in water
Poor backwashing practices
Excessive flow rates
Improper media selection

The correct answer is: Poor backwashing practices

Mudball formation, filter media cracks, or shrinkage are typically associated with poor backwashing practices. Effective backwashing is crucial for maintaining the efficiency and longevity of a filtration system. When backwashing is inadequate, it can lead to the accumulation of debris and sediment on the filter media. This accumulation prevents proper filtration and can cause the formation of mudballs as excess material clumps together. Additionally, poor backwashing may not adequately displace trapped particles, which can lead to the degradation of the filter media itself. Cracks or shrinkage of the media can occur due to excessive pressure or blockage, which is often a direct consequence of not properly cleaning the filter through backwashing. Maintaining a consistent and effective backwashing procedure is essential to ensure that the filter operates efficiently and to prevent issues such as these from arising.
