Ammonia stripping / decomposition process

Ammonia recovery of required concentration

The ammonia in the waste water is recovered as ammonia aqueous solution or gas.
Ammonia decomposition by catalytic reactor is also possible.


  • Ammonia recovery of required concentration
  • Energy-saving type with heat pump
  • Complete decomposition of recovered ammonia by using catalyst
  • Air stripping with out using steam is possible.In addition, recovering stripped NH3 gas as salt solution by acid is possible.

Application examples

  • Waste liquid containing ammonia, distillated waste liquid of evaporator, waste liquid of semiconductor system.
