Treatable Compounds

Aerisa ionization technology “casts a broad net” over a host of odorous compounds related to wastewater and 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.

Most wastewater-related odorous compounds have IEs less than 12.07 eV (O2), to include Hydrogen Sulfide (10.46 eV) and Ammonia (10.07 eV).  Ionization has a unique capability to treat many types of compounds at the same time. Besides the H2S and NH3 stated above, it will oxidize mercaptans, reduced sulfur compounds and nitrogen compounds such as amines and skatoles. This capability makes Aerisa a great choice for your odor control needs.

For industrial applications, ionization is highly effective for VOC reduction.  Click here for more information.

“Within hours we noticed a significant improvement in our air quality. Now, six months later, the odors have been completely eliminated, and we’ve had no further odor complaints from the surrounding community. I would definitely recommend this system to any wastewater treatment facility facing similar issues. The Aerisa team delivered great results by solving our odor issues while saving us money on installation and long term operational costs.”
