A. Backwashing filtering systems are available and are great for some applications (sediment filters, acid neutralizers, ion exchange systems, etc.). When used on a carbon system, it will remove the sediment buildup around the carbon, but does nothing to clean the actual carbon. Carbon absorbs chemicals like a sponge absorbs water. Once saturated, the carbon can no longer absorb any more chemicals and it must be disposed of. As of right now, we are not aware of any way in which the carbon can be cleaned and recycled.
