<p>A method and apparatus for stripping ammonia from an alkaline regenerant solution used for the regeneration of a zeolite ion exchange bed. The regenerant passes through a stripping column. An acidic working solution is circulated from a holding tank through a vacuum creating means and then back into the holding tank. The ammonia is stripped from the regenerant under a vacuum created in the stripping column by the vacuum creating means so as to cause the stripped ammonia to chemically react with the working solution to form an ammonium salt solution. Carbon dioxide free air is passed upward through the column countercurrent to the flow of regenerant.</p> |
