an aeration chamber
a clarifier
In a past article, we discussed the benefits of 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
