Section 2. Treatment Process Overview
Fuji Clea ’s o ta t filtratio treat e t is a si ple, ell e gi eered pro ess that o sists of a o trolled, ir uitous
flow train through anaerobic and aerobic chambers and in direct contact with assorted proprietary fixed film medias
on which biological digestion of organic matter occurs. Media is also designed and positioned to provide mechanical
filtration of process wastewater.
The system includes two air lift pumps (see diagram below) The Recirculating Airlift Pump returns process water and
sludge from the aerobic zone to the sedimentation chamber, recirculating 2-4 times inflow per day for CE models and
4-6 times inflow for CEN (enhanced denitrification) models. The Effluent Airlift Pump is designed to help equalize flow
and discharge treated effluent.

Blowers
State-of-the-art linear
diaphragm air blowers manufactured
by Fuji Clean Co sized to provide
about 2.8 cubic feet per minute to
most residential systems.
Chamber 2.
Anaerobic Contact
Filtration Chamber (spherical-
skeleton filter media) organic matter
decomposition by micro-organisms,
suspended solids captured and
nitrates are denitrified
Chamber 3A
. Storage Chamber (settling zone)
Two Air Lift Pumps. One
Recirculating Air Lift pump sending
process water and solids back to
Chamber 1, and one Effluent Air
Lift Pump for measured discharge
of treated effluent. (See airlift
pump info below).
Airlift Pumps. This generic illustration
sho s the e ha i s of the airlift
pu ps used i this s ste , hi h are
simple pipe conduits through which
pressurized air (from blower) is
introduced at the bottom and by fluid
pressure, water
is carried up the pipe
by ascending bubbles.
Flow Equalization
When water level
exceeds LWL, treated
water is discharged
through Chamber 3B
via the Effluent Air Lift
pump. If water level
exceeds HWL, then
treated water is also
discharged through an
overflow effluent weir.
Overflow Effluent Weir
During treatment,
water level fluctuates
between high and
low water levels
