Biological removal of ammonia from wastewater
WebJan 30, 2024 · Nitrification is the most common way to biologically remove ammonia in wastewater lagoons. In this process, ammonia treatment occurs courtesy of bacteria already present in the water. These bacteria break down the ammonia and eventually promote the release of nitrogen gas into the atmosphere.
