2.0 General Description of System
The Puraflo peat biofilter is an advanced
secondary treatment system that purifies
septic tank effluent to an extremely high
degree before final dispersal.
A typical Puraflo peat biofilter system
consists of:
Septic tank with a commercially-rated
effluent filter, with 1/32" filtration,
connected to the tank outlet pipe
Dosing tank and effluent pump, or siphon,
to accommodate dosing of the septic
tank effluent onto the peat fiber media
Biofilter modules where advanced treatment
occurs due to the physical, chemical and
biological processes that are optimized in
the peat fiber media.
Site specific, final effluent dispersal system
The filtered septic tank effluent is collected
under gravity in the pump tank. A timed dosing
system is activated by a programmable timer
or a siphon-dose system triggers, which
pumps the effluent through a flow splitting
inlet manifold located at the base of the
treatment modules. An orifice plate is located
inside the top of each inlet manifold which
allows the flows to be split equally and fed
simultaneously to each biofilter module.
The inlet manifold is connected to the base
of the biofilter module and is fed upwards to
a rectangular distribution grid located 6 inches
below the top of lid. The effluent percolates
laterally and vertically through the depth of
the peat fiber treatment media and emerges
as a clear, innocuous liquid from the base of
the system. The treated effluent is then
collected and dispersed.
The Puraflo peat biofilter system has been
tested, certified and listed by the National
Sanitation Foundation, International as
meeting the requirements of NSF/ANSI
Standard 40, Class 1. Puraflo is a modular
system with each module rated for 150 gallons
per day (gpd). The range and rated capacity
of the system is therefore a multiple of the
standard unit based on the 150 gpd per
module. Model P150N*3B, incorporating 3
modules and rated at 450 gpd, was the treat-
ment plant tested to NSF/ANSI Standard 40.

3.0 Introducing Substances to the System
The Puraflo peat fiber biofilter is designed for the treatment of domestic strength wastewater from
residences or other waste flows with similar wastewater strength characteristics. While the Puraflo
peat fiber biofilter will process most waste produced by the average household, in order to prevent
malfunctions, and to ensure optimum performance of the system, the following guidelines should
be followed:
Don’t:
Overload the system by introducing waste-
water flows greater than the design flow
Flush excessive amounts of grease, oil or
fat into your septic system
Dump excessive amounts of disinfectants,
cleaners or detergents (normal amounts
will not harm the system)
Allow storm water into your septic system
(storm water drains should not be connected
to the septic tank and landscaping should
divert storm water away from the modules)
Use additives (septic tank additives should
not be introduced into the septic tank for
grease reduction, stimulation of biological
activity or other purposes)
Dispose of large quantities of organic mate-
rial through a garbage grinder as this may
organically overload the system and cause
more frequent pumping of the septic tank
Flush cigarettes, tea bags, sanitary napkins,
tampons, diapers, condoms and other
non-biodegradable products capable of
blocking pipes or filters into your system
Dump solvents, oils, paints, thinners,
pesticides or poisons down the drain which
can disrupt the treatment process and
contaminate the groundwater
Dispose of water softener waste directly
into the septic system (where practical
design a separate disposal system or
balance flows into the septic system)
Do:
Conserve water to reduce the amount of
wastewater that must be treated and
dispersed
Repair any leaking faucets and toilets
(very important!)

4.0 Homeowner Do's and Don'ts
To ensure optimum performance of the Puraflo peat fiber biofilter system, the following Do’s and
Do Not’s should be followed:
Don’t:
Dig in your drainfield or build anything
permanent over it
Plant anything over your drainfield except
grass
Drive over your drainfield or compact the
soil in any way
Attempt any homeowner maintenance to
the septic tank, pump tank, electrical
controls or treatment modules – do not
remove caps or covers as potentially
hazardous gases and waste matter are
contained in the treatment tanks which
may result in death or bodily injury
Place heavy objects on or drive across your
treatment system
Bury or cover the modules with soil as the
Puraflo treatment is an aerobic process
that requires free passage of air through
the module lids
Do:
Maintain a stabilized/grassed landscaped
area around the modules in order to prevent
soil erosion (plants and suitable shrubs can
also be used to enhance the appearance of
the system)
Keep ant nests and other pests out of the
treatment modules by dosing externally
with suitable insecticides and pest controls
as necessary
Divert down spouts and other surface
water away from the system and drainfield
Keep your septic tank cover accessible for
tank inspections and pumping
ave your septic tank pumped regularly
and checked for leaks and cracks
ave the effluent filter cleaned annually
Test the pump alarm occasionally
(as applicable) by briefly activating the
test switch on the alarm
In the event of the alarm sounding after
electrical storms or power failure, check if
the electrical circuit-breakers tripped off
by first turning them off and then turning
them back on again
Call your Authorized Service Provider when
you have problems

5.0 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 Sept c 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. owever, 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 omeowner Troubleshooting
Checklist in the event that the control panel
alarm is activated.
5.3 Electr cal 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.

No heavy objects should be placed on top of
the system modules as imposed loads can
adversely effect the distribution and hence
the performance of the system. The modules
can be camouflaged with plants and small
root ball type shrubs placed no closer than
2 feet from the modules, however, no soil or
other obstruction should be placed within
four inches from the top of the module where
air is naturally circulated through the system.
5.4 Puraflo Modules
It is essential that the treated effluent is
allowed to drain freely from the modules and
that the final disposal system is kept in good
condition. Failure of the final disposal system
may cause backing up of effluent in the
Puraflo modules which could damage the
treatment capability of the system and the
peat fiber. The Authorized Service Provider
should be notified if there are any indications
of ponding on the final disposal system and
either standing water in or overflow from the
modules or sampling chamber.

Item Description
6.0 acation, Seasonal and Intermittent Use
The Puraflo system will function normally when
used in vacation, seasonal or intermittent
homes. During normal operation of the Puraflo
peat fiber biofilter a stable ecosystem exists
in the peat fiber media consisting of a diverse
population of microorganisms and also higher
life forms. During a period of reduced waste-
water flow to the Puraflo modules, the microbial
population correspondingly decreases in the
media. The degree of ‘feeding’ of the system
dictates to a certain degree the microbial
numbers in the media, however, the system
will continue to treat the wastewater. The
reason for this is that upon complete cessation
of wastewater supply to the bed a number
of changes occur to the resident microbial
population. Many types of bacteria and fungi
will form spores during periods of nutrient
depletion. These spores will remain dormant
until a fresh supply of wastewater is added
to the modules. Other non-sporing microor-
ganisms will remain in a dormant inactive state
until fresh nutrients are provided. Some
microorganisms and higher life forms will
persist in the peat fiber media feeding on the
residual biomass present, thus turning over
the microbial population in the peat.
Upon start up, when wastewater is once
again supplied to the system, the dormant
microorganisms and spores quickly resuscitate
and become metabolically active. Additional
beneficial bacteria will be provided by the
wastewater itself. The Puraflo peat fiber
biofilter very quickly reactivates to become
fully efficient.

7.0 Troubleshooting Checklist
Experience slow-flush but electrical
system is operational
Alarm sounds continuously and effluent
level rises steadily in the pump tank –
this can eventually lead to slow-flush
caused by sewage backing up and
could eventually cause effluent to
pond at the septic or pump tank
Alarm sounds periodically but resets
itself (indicating that the pump is still
operating)
Note: Some states require alarms that
are latched (continue to alarm after the
alarm event has been corrected) and
will not auto-reset themselves in which
case it will be necessary to reset the
alarm manually
No alarm warning – effluent level rises
continuously in the pump tank potentially
leading to slow-flush and/or effluent
