Almost all commercial products contain ammonia. The ammonia runs through water system and results to wastewater. This article discusses the techniques in removing ammonia from wastewater.

Nowadays, almost all cleaning agents contain ammonia. Many window sprays, toilet bowl cleansers, oven foam and a lot more household cleaners usually contain ammonia. These commercialized products with ammonia are made with regulated concentration of ammonia because ammonia can be hazardous. Even in a very low concentration, inhaling air with ammonia, or getting the solution on your skin can more often cause injuries like burning, fainting or, worst, death. Since ammonia is used often industrially, we should be alarmed of their waste products that usually results into wastewater. With these facts, we should be wary about how to remove ammonia from waste water.

There are several ways in removing excess ammonia in the wastewater. One of the methods developed is with the use of a Steam Stripping, Catalytic Oxidation and Self Steam Compression. These are some of the technological system developed to control the ammonia level in the wastewater. It will all start with the ammonia-rich wastewater, fed into the Ammonia Stripper. This wastewater will be heated up with the help of steam. Then, the ammonia in the wastewater will be stripped into the steam, which would produce ammonia-rich steam. This ammonia-rich steam will be released from the stripper and then it will go directly to what we call the Steam Compressor. Now while inside the steam compressor, the ammonia-rich steam will be reheated and then the ammonia-rich steam will then be utilized as the heat supply for the Reboiler. Another process will take place in the Reboiler. After the heat trading at the reboiler, the ammonia-rich steam will go to the Ammonia Catalytic Converter. The converter will then decompose the steam and turn parts of it into Nitrogen and some into just regular gas. After all the reactions that happened, it is important to know that the gas would still contain some minute amount of ammonia. The gas would be cooled down, and then they would release it.

Although the gas contains harmless amount of ammonia, if it will accumulated, it’s pretty much hazardous too. So another method proposed is by using Nitrifying bacteria. This method is surely Earth-friendly because these bacteria are naturally occurring in our environment and they also convert the excess ammonia into something that can be useful to other organisms. There are two kinds of Nitrifying bacteria that works on the excess ammonia. The first one is the Nitrosomonas spp. converts the excess ammonia into Nitrite. This nitrite will be then converted to Nitrates by the second nitrifying bacteria called Nitrobacter spp. The nitrates can now be maximized by the organisms that need it.

Membrane contractor is also a popular way on eliminating excess ammonia in the waste water. In this membrane contractor, the ammonia will be eliminated immediately and then will be converted into some kind of ammonia salt. It’s like hitting two birds with one stone. You’re eliminating ammonia in the wastewater and at the same time, you can also make fortunes by profiting with this ammonia salt.

In Japan, they are really making efforts in discovering ways on how they can eliminate ammonia in waste water. Their government is mandating that ammonia should only be no more than 100 ppm in water.
