This question asking what can be done for air binding in filters is from a reader who was having a problem with entrapped air causing the filter runs to be cut short, thus losing media during backwashing. The article recommends that the filter should be filled slowly from the bottom until the media is covered. This will exhaust air trapped in the filter and prevent the media from being further disturbed by incoming water. Recommendations for backwashing a filter with retained air are also given. Training opportunities are mentioned, along with a new manual on filtration.
