Ammonia can be hazardous to the environment and that is why its concentration must be regulated. For instance, when ammonia leaks into a stream or lake, it is disintegrated into nitrates by oxygen-thriving organisms. Too much nitrates can degrade the water supply and overall quality of the habitat. There are many ways of removing ammonia from wastewater, and one of the most effective is the ion exchange system. It is highly favored because of its flexibility, low labor demand and affordability. Pollutants in the water are seemingly encouraged to degrade with the use of aerador.
Ion exchange systems can be installed easily into existing wastewater treatment equipment possibly a tanque. It must be installed at the point where ammonia is introduced well before it gets to the main wastewater stream. Alternatively, it can be installed at the end of the waste treatment process prior to discharge. Either way, these systems can also be easily uninstalled. For instance, once the ammonia source has been determined and removed, the columns may be returned to the vendor easily. Ion exchange equipment consists of a number of columns that contain resins and a pump, along with a filter for the removal of particulates.
The first column gets filtered wastewater and often contains carbon, which can remove organics from the water to avoid fouling the resins contained in the other columns. The next columns have ion-selective resin which is created for the removal of ammonia. For several applications, ion exchange systems can be put up small scale with a 2 ft x 8 ft footprint or smaller. The required flow rate and the ammonia concentration in the wastewater dictate the size of the system.
In terms of regeneration, ion exchange resins do get drained after several uses, meaning they become less effective. When this happens, ion exchange resins can be regenerated so they can work like new again. There are two options for this, and one is onsite regeneration. In this case, there has to be a hard-piped regeneration system installed. This is an expensive method because capital equipment and chemicals must be purchased. Aside from the ion exchange system itself, extra space is also needed, as well as a method for the treating the chemical-filled wastewater used in the regeneration process.

The second option is the exchange of columns for offsite regeneration. There are some industrial water treatment companies that have column exchange programs, the most versatile option for manufacturers. This process involves the vendor exchanging columns that contain the exhausted reins for fresh ones. This means wastewater treatment systems can continue to work while the exhausted resins are regenerated. Since the process will be carried out offsite, wastewater treatment from a regeneration process is not necessary, and there is no requirement for more space.
