activated carbon filter is identical in its construction to the
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.
