Aerobic Recovery System On-Site Treatment Systems™

Description of Technology

Descriptions for proprietary technologies are from the Massachusetts DEP Approval Letters for the technology.

The System is designed to convert an anaerobic system into an aerobic system and reduce the strength of the wastewater received by the existing soil absorption system (SAS). Prior to System installation the septic tank must be pumped to remove settled solids. The System consists of an Aero-Stream aeration unit, 120 volts operated on a continuous basis, with an airline piped into an existing septic tank or a new septic tank designed in accordance with 310 CMR 15.223 through 15.228. The airline feeds a Micro Bubble Diffuser with floats within the septic tank. The adjustable floats are connected to the airline and keep the diffuser suspended at the proper level in the tank, typically 18 inches from the bottom.

Aerobic treatment is established in the septic tank and maintained using the AeroStream aeration unit. The aerator mixes the contents of the septic tank with the bacteria and aerates the wastewater. The System’s biomass reduces the strength of the wastewater in the septic tank. The aerated effluent from the septic tank is designed to reduce the thickness of the existing biomat in the SAS, thereby improving the soil absorption capacity.
