If media collects in the wash water troughs, what does it indicate?

When media collects in the wash water troughs, it indicates that the wash rate is too high. A high wash rate can cause excessive turbulence and flow velocities, leading to the mobilization of media that should ideally remain stationary in the filtration system. The primary function of the wash water is to remove accumulated solids without displacing the filter media. Therefore, if the media is being washed out, it suggests that the operational parameters of the washing process are not properly calibrated, emphasizing the need for careful monitoring and adjustment of the wash water flow rates to ensure effective cleaning without media loss. This understanding is crucial for maintaining the efficiency of the filtration system and avoiding the need for frequent media replacement.
