Aerobic treatment units use biological processes to transform both dissolved and solid constituents into gases, cell mass and nondegradable material. Aerobic treatment units typically include three primary components:
a trash tank
an aeration chamber
a clarifierThere are benefits to a trash trap, but sometimes ATUs are installed without either a trash trap or a clarifier. The generic terminology for these types of systems is an adaptive mechanical aerator. An AMA is a hybrid aerobic treatment unit that introduces air into a treatment component. Air is introduced to increase the oxygen available for digestion of organic matter and subsequent reduction in biochemical oxygen demand and total
