chi-blocking is "energy blocking". It blocks the chi flow through the body, causing undesirable effects. It may be temporary or maybe semipermanent (i.e. requires very advanced techniques to unlock, techniques that may be long lost or knowledge of which is restricted to few selected creature like lion turtle, thus Amon believes noone can give his victims' bending back) or permanent. So it is very possible that Zolt or Tahno have their bending ability "locked", and some very advanced technique (that they do not know to even exist) is needed to give thier bending back.

But when Amon does takes bending away, there is no energy coming out from victim's body; when Aang took Ozai's bending away, a powerful blue ray shoot to the sky.
