The aeration stage and the disinfecting stage are the primary differences from a traditional septic system; in fact, an aerobic treatment system can be used as a secondary treatment for septic tank effluent. [1] These stages increase the initial cost of the aerobic system, and also the maintenance requirements over the passive septic system.
Onsite sewage facilities (OSSF), also called septic systems, are wastewater systems designed to treat and dispose of effluent on the same property that produces the wastewater, in areas not served by public sewage infrastructure. A septic tank and drainfield combination is a fairly common type of on-site sewage facility in the Western world.
A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [ 3 ] organic waste, such as food, cardboard and horticultural waste.
A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of some material, such as rocks , coke , gravel , slag , polyurethane foam , sphagnum peat moss , ceramic , or plastic media, over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm ) to grow, covering the bed of ...
Effluent sewer systems, also called septic tank effluent gravity (STEG), solids-free sewer (SFS), or septic tank effluent drainage (STED) systems, have septic tanks that collect sewage from residences and businesses, and the liquid fraction of sewage that comes out of the tank is conveyed to a downstream receiving body such as either a ...
