The activated carbon filter is identical in its construction to the media filters.
This filter uses a double bottom chamber separated by a welded reinforced steel plate. The upper chamber contains the granular activated carbon and the lower chamber is empty and collects the filtered water. The plate is covered by "mushroom" diffusers, which are plastic made, slotted conical units. The uniform dispersion of water ensures an effective wash of the whole media volume, avoiding the phenomena of channeling (caking). The filters are particularly suitable for backflushing - a process involving reversal of the water flow and causing a turbulent expansion of the media like a fluidized bed.
After the backflushing is completed, the filter resumes its normal filtering mode as clean as a new filter.
