Yes. There are some OEM pre-qualification requirements for specialized applications such as this. The OEM should have experience/expertise with filtration and acid/caustic handling. 3M has written a Technical Brief regarding the ammonia recovery process; it is found in our download section.  Please note that: (a) Liqui-Cel end caps need to be Noryl material. (b) Liqui-Cel is best used in a rough reduction of NH3 and will not provide a high reduction. (c) The residual NH3 would need to be removed by ion exchange resin. (d) Sulfuric acid is typically used in the Liqui-Cel module for this application which requires special design/materials of construction. If the end use is to precipitate out the ammonium sulfate for use in sales as fertilizer, a final precipitation step is needed.
