Operation and Maintenance
The Puraflo peat fiber biofilter is a passive biological treatment system. There are no mechanical
parts with the exception of the pump and controls which dose the treatment modules. To assure
the efficient operation of the Puraflo system, it is important that the septic tank is well maintained
and sludge carryover is avoided. The measures recommended for a standard septic tank treatment
system also apply to the Puraflo system which works on the same basic principles. To ensure opti-
mum performance of the Puraflo system, the practices outlined below should be followed.
5.1
Septic Tank
A well maintained septic tank is essential for
most on-site treatment systems as the septic
tank provides the first step in wastewater
treatment (also called primary treatment).
During use, the heavier solids settle to the
bottom forming a sludge layer while the
lighter solids, greases and oils float to the top
to form a scum layer. The anaerobic conditions
created in the septic tank by the scum layer
allow anaerobic and facultative microorgan-
isms to break down (feed on) and reduce the
sludge and scum volume. In this manner
approximately 40 percent of sludge and
scum volume can be reduced. However, the
remaining solids accumulate in the tank and
must be pumped out on a regular basis.
The septic tank should be inspected annually
and pumped in accordance with State and
Local guidelines. Depending on use, a typical
home will produce sufficient sludge requiring
the septic tank to be pumped every 2 to 10
years. The importance of desludging can
not be over-emphasized since the Puraflo
system is designed to treat effluent from a
well functioning septic tank where a significant
portion of insoluble solids have been allowed
to settle out. The effluent filter installed with
the Puraflo system should be cleaned annually
or at the time of system inspection. The
inspection/desludging should be carried out
by a qualified septic pumper and should not
be attempted by the homeowner.
Note: A filter is installed on the septic tank
outlet pipe to prevent the carry-over of solids to
the treatment system. If septic tank mainte-
nance recommendations and practices are not
followed and in particular, if large objects are
disposed into the septic tank, the filter will clog
causing wastewater to backup into the house.
5.2
Pump Alarm
The pump alarm should be checked on a regular
basis by briefly pushing the test switch on
the alarm. This activates the audio alarm
buzzer and visual alarm light for a short peri-
od before it reverts to its automatic position.
Refer to the Homeowner Troubleshooting
Checklist in the event that the control panel
alarm is activated.
5.3
Electrical Control Panel
In the event of an electrical storm or power
failure, the circuit-breaker switches on the
electrical lines feeding the Puraflo pump and
alarm should be checked to see if they
tripped to the “off” position. If a circuit
breaker switch is tripped, the power supply
to the alarm/pump should be restored by
resetting the breaker. If the Puraflo system
still fails to operate, please call the
Authorized Service Provider or Anua.
