Treatable Compounds

Aerisa ionization technology “casts a broad net” over a host of compounds related to industrial processes. The effectiveness of ionization is related to the ionization energy of the compound to be treated. Ionization energy (IE) of an atom or molecule describes the minimum amount of energy required to remove an electron from the atom or molecule in the gaseous state. Those chemicals with lowest IE are most amenable to treatment by air ionization. Those with an IE greater than that of oxygen (since ionization creates oxygen ions) are more difficult.
