Ammonia is a prevalent problem in the wastewater of many industries. Because Ammonia is widely used as a cleaning agent in many processes, it will end up in the plant wastewater and it must be treated or removed from water prior to it being discharged back into the environment. Membrane Contactors offer a great alternative for removing ammonia from wastewater in many industries and our membrane contactors can remove up to 95% or more of the incoming ammonia.

Contactors extract ammonia from wastewater and convert it into a harmless ammonium salt which has some commercial value as a fertilizer. All systems will vary based in the process parameters and our technical service engineers will be happy to size a system based on the parameters of your application. Ideal process parameters for ammonia removal with  Membrane Contactors are as follows:

• NH3 inlet concentration > 500ppm
• Pre-filtration <5µm abs
• Temperature 40-55°C
• Feed stream pH>10
• Acid stream pH<2
• Sulfuric Acid as stripping media, 96% by weight
