An air stripping unit is a process used to remove volatile gases such as hydrogen sulfide, hydrogen cyanide, and ammonia from wastewater by blowing air through it. This process facilitates the transfer of contaminants from a liquid phase to a gas phase, effectively removing nitrogen compounds. The principle behind air stripping units involves the high solubility of ammonia in water, requiring a large quantity of air to transfer ammonia from the water to the air. There are three different configurations of stripping units, which are detailed in literature such as Montgomery (1985).
