System and Terminology
The Aero-Stream AS500-3, AS500HO-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. Aero-Stream,
AS500-3, AS500HO-3, AS650-3, AS750-3, AS1000-3, and AS1500-3, Bio-Brush, & Aero-Alert are
trademarks of Aero-Stream, LLC.
The air compressor delivers a constant flow of air through the air line to the diffuser(s). The diffuser
assembly is installed in the center of a Bio-brush clusters. The diffuser breaks 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
stabilize 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.
An effluent filter (if required by local or state codes) in the outlet baffle prevents large objects from
entering and clogging the outlet pipe.

Unpack and Inspect Parts
Remove and identify the product from the package and check for any missing or damaged parts. The
images shown are representative only as this manual covers multiple models.
Handle the parts carefully! The air compressor and sintered stone diffuser(s) are especially fragile and
can be easily damaged.

Exceeding the design flow rate limits will allow high strength wastewater to flow into the absorption
component and cause premature failure of the absorption component.
A properly functioning system will be completely odorless. If odors are present, this indicates an
equipment or process malfunction. Contact your authorized service provider listed on the label of the
product, the front cover of this guide, or Aero-Stream at 877-254-7093.
Your system has an audible and visual alarm to alert you of system issues. An alarm event sound
indicates a high water event or a lower air event. Contact the authorized service provider to correct the
issue. Have the model name and serial number, as found on the bottom plate of the enclosure unit,
available when contacting the authorized provider.

Installation Process –Bio Brushes
Figure 10, Single Bio-Brush Cluster
1. Figure 10 above represents a single Bio-brush cluster. The brush cluster is comprised of a top float
ring, center media fibers, & the bottom ballast ring. Bio-brush clusters will need to be connected at the
base (bottom ballast ring) as shown in Figure 11 through Figure 15. The brush fibers are hidden for
clarity in the following figures. The process of connecting the brushes and rings is best completed
inside the tank. Do not remove any cable ties from this assembly.

2.Connect the black poly tubing together at base of Bio-brushes as shown in Figure 16 by slipping
provided Oetiker clamp over tubing & sliding tube onto barb fitting. Secure Oetiker clamps at joint as
shown in Figure 17 and 18 by crimping ears of clamp with Oetiker Tool or Side Cutters/Cutting Pliers.

3.Once fully assembled, carefully cut and remove the packaging stretch wrap and discard. Cut a slit in
the poly wraps on the Bio-brushes about (1) inch long along the axis of each Bio-brush. Grasp the poly
sleeve opposite of the slit and tear the sleeve downward until it is completely removed from the Bio-
brush. Discard the poly sleeve. Repeat this for each Bio-brush.
Figure 19, Bio-Brush Unwrapped
4.After all clusters are unpackaged, systematically raise each Bio-brush vertically from the tank floor
(Figure 21) and feed each of the yellow float ropes through the lid of the tank.
5. For AS500-3, AS500HO-3 (Figure 11), AS650-3 (Figure 12), AS1000-3 (Figure 14), and AS1500-3
(Figure 15), the center-outlet side Bio-brush cluster should be slid over the center outlet housing as
noted in Figure 20.
The AS750-3 model (Figure 13) incorporates an offset outlet housing configuration using the same
process for positioning the Bio-brush around the outlet baffle.
Figure 20, Bio-Brush Cluster installed around Outlet Baffle
6.Raise the float rings vertically until the Bio-brushes are fully extended. Feed yellow ropes through
access port of tank and temporarily anchor ropes.

Installation Process –Diffuser(s) and Air Line
1. Locate on the approved plans where the air line will exit the tank (for example, through the side of a
riser, or tank top). As required, drill a 5/8-inch hole. (Figure 21 and Figure 22). Models AS1000-3 and
AS1500-3 with multiple air compressors will require multiple holes.

2. Remove two-(2) stainless screws from center diffuser section. See Figure 23.

3. Slide ballast tube onto bottom of diffuser section (Figure 24) with a slight back and forth twisting
motion until the small hole on diffuser section is in the center of the large hole in ballast tube. Insert
screw and tighten until screw head is flush. Repeat process for attaching float tube to top of diffuser.
(See Figure 26)
Figure 24, Ballast and Float Tube Install
4. Slide air line retainer towards top of float tube. Retainer should be approximately 1” below the top of
the float tube. See Figure 25.
Figure 25, Float Tube Air Line Detail Figure 26, Diffuser Fully Assembled
Repeat step 2 through step 4 as needed for models containing multiple diffuser assemblies (AS1000-3
and AS1500-3).

5. Fill the tank with water or wastewater prior to installation of the diffuser assembly. Slowly lower the
air line and diffuser assembly into Bio-brush cluster (Figure 27) in the location shown in approved plan.
When the diffuser hits the bottom of the tank, you will feel the air line become light. Diffuser should be
in vertical position.
