Why is a water distribution system used for side filters?
Since a water distribution system is used, it is presumably to ensure even distribution to the filter media layer.
The function of the water distribution system is to ensure even distribution of backwash water across the entire surface of the filtration unit, while also enabling uniform collection of the filtered water during filtration. The distribution uniformity of the water distribution system has a significant impact on the effectiveness of backwashing. Uneven water distribution can cause some filter layers to expand insufficiently, while other layers expand excessively. In the areas where expansion is insufficient, the filter media cannot be cleaned properly ； In areas with excessive expansion, \"sand migration\" can occur; when the pebbles in the cushion layer move, it leads to \"sand leakage\".
