How an Aerobic Septic System Differs from a Traditional Model
Aside from the presence of oxygen, there are some other striking distinctions between how the two designs operate. With a conventional model, all the wastewater from a building enters a tank through a primary line. The majority of tanks have two compartments, though a few of the older ones have a single compartment. As the wastewater streams into the tank, it divides into three layers. The buoyant materials, such as grease and toilet tissue, increase to the top, and the dense products sink to the bottom. The liquid in the center is described as "effluent," which moves from one chamber to the next, then is dispersed into an underground absorption field or leach field, where the bacteria in the soil completes cleaning it before it reaches the water table.
