Activated
carbon scrubbers are very effective pollutant
filters/scrubbers in both air phase and liquid
phase applications. But, when the activated carbon
becomes saturated with the pollutants the effectiveness
of the scrubbers falls off rapidly until catastrophic
failure occurs. Then the activated carbon scrubber
becomes a pain from a maintenance standpoint because:
First, it is no longer doing its job of removing
pollutants from the waste stream.
Second, activated carbon reactivation, replacement
and disposal are costly and a hassle to deal
with. In fact in many situations it never happens.
» Activated Carbon and Ozone Interact
Synergistically
Activated carbon and ozone work well together:
First, ozone is powerful oxidant, so it will
remove many of the pollutants before the pollutants
reach the activated carbon.
Second, any unused ozone will oxidize the pollutants
adsorbed by the activated carbon thereby cleaning
the carbon and ‘reactivating’ it.
As a result, when ozone and activated carbon
are used in conjunction with one another, the
effectiveness of the pollution control system
remains continually highly effective and the activated
carbon lasts almost indefinitely.
