Expert Solution
Step 1
  •  In this process, ammonia treatment occurs via bacteria already present in the water.
  • These bacteria break down ammonia and eventually promote the release of nitrogen gas into the atmosphere.
  • Water containing ammonia is treated by ammonia react with the disinfectant hypochlorous acid (HOCL) in solutionto form monochloroamine (NH2Cl)
