Ammonium Removal

Ammonium Removal via Efficient Ammonia Stripping

Reliable removal of ammonium (NH₄⁺) from wastewater, construction water, and groundwater—using Prantner’s proven countercurrent stripping technology.
Ammonium-containing waters are a key environmental and permitting issue in many industries. Our systems reliably convert ammonium into gaseous ammonia and remove it through efficient stripping processes.

Process Principle

In a first step, the bound ammonium is converted into free ammonia under alkaline conditions. This is then stripped from the wastewater in a Prantner packed-bed countercurrent column—a robust and energy-efficient process that operates reliably even under high loads. This process corresponds exactly to the process used in previous Prantner technology and forms the core of our ammonia desorption systems.

Technical Highlights

  • Packed counter-current columns for high separation efficiency
  • Efficient air or gas flow for optimal stripping performance
  • pH adjustment to ensure safe ammonia release
  • Optional: Exhaust air treatment / activated carbon / scrubbers, depending on the project
  • Can be automated for continuous industrial processes
  • Modularly expandable
