Raw sewage is gravitated into the primary zone. Here the sewage is aerated as it passes through a constant stream of air bubbles, and the solids are broken up. The solids settle to the base of the unit and are drawn back up the distributor pipe by the bubble diffuser. When raw sewage enters the primary zone, mixed effluent is pushed into the equiescent zone where the solids fall out of suspension and return to the primary zone. The effluent which has undergone treatment flows into the outlet trough and is pumped or gravitated to the ditch, stream or soakaway.
