PROCESS DESCRIPTION
1. Sedimentation Chamber
This chamber is designed to physically separate solids
from the incoming water. Scum is the floating material
and sludge is the material that has settled at the bottom.
2. Anaerobic Chamber
This chamber contains a spherical skeleton-type filter
media, 4.3 inch diameter (109 mm). Through bacterial
growth processes on the surface of the filter media,
biological anaerobic treatment thrives while suspended
solids are captured. Furthermore, the microorganisms
in this chamber convert nitrates in the recirculated water
returning from the aerobic chamber to gaseous nitrogen.
The gaseous nitrogen then escapes to the atmosphere.
3. Aeration Chamber
The aeration chamber consists of an aerated upper
section and a filter media lower section. The chamber is
filled with hollow, cylindrical filter media 0.6 inch diameter
(15 mm) and 0.55 inches long (14 mm). Biological
treatment takes place on the filter media surface.
Aeration is continuous. Residual suspended solids are
captured by the filter media circulating in this section.
During normal operation, a recirculation line transfers
water back to the sedimentation chamber by way of an air
lift pump.
The filter media in the aeration chamber are backwashed
regularly (twice a day, 5 or 10 minute cycle) by the
backwash system located at the bottom of the chamber.
The accumulated sludge is transferred by an air lift pump
back into the sedimentation chamber for further digestion.
4. Storage Chamber
This chamber is designed to temporarily store treated
water exiting the aeration chamber. This treated water is
ready for discharge.
The complete wastewater treatment system will typically consist of
the Fusion ® treatment components and a soil absorption field for final
disposal of the liquid effluent. Some states or counties may require
the addition of a septic tank before the Fusion ® to increase the
sedimentation chamber capacity and retain more solids. Please see
Figure 11 for a typical Fusion ® system. Variations to the typical system
will be made to suit your particular site and system design needs.
Please contact your authorized Fusion ® installer or maintenance
provider for further information about your system design.

CERTIFICATION MARK
The Fusion ® treatment unit comes with an electronic, dual-
port blower designed specifically for use with this system. The
blower utilizes a linear motor and two diaphragms to generate
the air flow necessary to aerate and recirculate water within the
system. This style of compressor is quieter and more efficient
than traditional rotary vane compressors. Once installed and
adjusted, circuitry within the blower will automatically switch the
unit from normal recirculation mode to backwash mode and back
again when appropriate. In the event of a power outage, the
blower will stop, but a backup battery within the unit will retain
the correct time and backwash settings.
