The present invention comprises a method and a system for the treatment of liquid, such as coming from an air washer for removing ammonia from air streams, wherein the method comprises the following steps: (a) providing nitrite-comprising liquid, preferably from washing ammonia-comprising air; (b) adding a nitrite-converting substance, preferably sulfamic acid to the system, wherein the nitrite in the liquid is chemically converted into nitrogen gas, leading to a treated liquid. The invention can be used for the treatment of air streams generated in fertilizer processing, biogas plants, composting processes, livestock farming or industrial processes. |
