Overview of AS500-3, AS650-3, AS750-3, AS1000-3,
AS1500-3 System and Terminology
The Aero-Stream®AS500-3, AS650-3, AS750-3, AS1000-3, AS1500-3
systems use an aerobic process to treat the wastewater prior to dispersing
into an absorption component.
The Aero-Stream enclosure, Figure 1, delivers a constant flow of air through
the air line to the diffusers. The diffuser assemblies are installed in the
center of the most downstream outer Bio-Brush®clusters. The diffusers
break the air flow into micro-bubbles that allow oxygen to be dissolved into
the water as the air bubble stream rises to the surface.
The Bio-Brush®clusters provide a media for attached growth bacteria. The
attached growth bacteria stabilizes the system during shock loading. The
Bio-Brush clusters also filter particulate matter from the mixed liquid.
Residual dissolved oxygen and suspended growth aerobic bacteria exit the
tank through the outlet baffle and pipe and enter the drain field, trenches, or
mound. The dissolved oxygen allows aerobic bacteria to live in the drain
field, trenches, or mound and further clean the wastewater.
The effluent filter (if required by local or state codes) in the outlet baffle
prevents large objects from entering and clogging the outlet pipe.
The AS500-3, AS650-3, AS750-3, AS1000-3, AS1500-3 systems are
designed to treat residential strength wastewater. This includes human
waste and moderate amounts of typical household cleaning products. See
Best Septic System Practices section of this manual for proper wastewater
system use.
