Ammonia is used as a cleaning and bleaching agent in the production of fertilizers, plastics, explosives, and many other products. Industries using ammonia have to treat their wastewater to remove ammonia so that it is not discharged back into the environment, where it can negatively affect human health, agricultural production, and natural ecosystems.

3M™ Liqui-Cel™ Membrane Contactors offer a great alternative to conventional ammonia removal methods that often produce secondary waste streams that are difficult to treat. The large surface area of Liqui-Cel membrane contactors facilitates fast separation of ammonia from wastewater. In addition, the membrane contactors can provide cost savings by reducing the ammonia load on the wastewater treatment system.
