Active Carbon

[mdm]

Can active carbon be "recharged"?

No it can't, once it is used up you have to replace it with new stuff.

It's a long thread about reusing old carbon.

Conclusion; you may be able to "recharge" old carbon but it's not really cost effective and the carbon will not be as good as the new one.
