How to recover ammonia from water?
Another option for recovering ammonia from waste water is to use the mechanics of the ammonia-water thermal absorption cycle. Using this option, ammonia can be recovered either as a liquid or as ammonium hydroxide. The advantage of the former is that it is much easier to handle and transport, whereas the latter also has a commercial value when a concentration of 30 percent ammonium hydroxide in solution is produced.
