System description and Operating principle
The Ecoflo® Peat filter system is a wastewater treatment system designed to treat domestic wastewater.
Your complete Ecoflo®Peat filter system includes a septic tank, an effluent filter, one or more Peat Filters
and, depending on the type of installation, a pumping station and a flow divider.
System description
The Ecoflo®Peat Filter is made of a concrete shell enclosing a
natural filtering media composed of two specific layers (bottom
and top layers) especially selected to treat residential wastewater.
Two polyethylene lids securely fastened limits the accesses to the
system. Under the main and secondary access lids is located an
insulating board that deflects the incoming air into 2 aeration
channel to feed the filtering media. That lid also insulates the
inside parts of the system.
Operating principle
To be treated, the wastewater goes first into the septic tank where it is submitted to a primary treatment. Then it goes through
the effluent filter, to prevent solids discharge to the effluent, and in the flow regulator to restrain the flow rate reaching the
Ecoflo®Peat Filter. Once inside the Ecoflo®, the water is directed into the tipping bucket in order to be split equally over the
distribution plates located on both sides of the central support plate. These plates include channels with orifices to distribute
the effluent evenly on top of the filtering media. Afterwards, wastewater trickles down into the filtering media where its
organic content is consumed by bacteria. The treated effluent is collected in the gravel bed and evacuated by gravity (STB-
650B series)or with an integrated pump (STB-650BR series).
Please take note that for models STB-650BR-H2/H3 series-A/NA the diagram differ slightly regarding the aeration and
drainage system but the same operating principle applies.

Peat filter system has been tested and listed
under standard 40. Each model of Ecoflo®Peat filter
described here meets Class I requirements as per ANSI/NSF
standard 40.

*Important: Gravity effluent discharge is available only in the STB-650B-H1-A/NA configuration.
Regarding the effluent discharge, there are two types of Ecoflo®Peat Filters (STB-650B and STB-650BR).
The first one has an effluent discharged by gravity to a pumping station, a disposal field, a tertiary treatment
or directly to a watercourse. The second one has a pump station included in the system that directs the treated
effluent to a disposal field, a tertiary treatment or a direct discharge to a watercourse.
There are also 3 heights of Ecoflo®Peat filter available depending on the local regulation. Models are H1, H2
and H3. They all have the same hydraulic loading rate, a nominal surface area of 70 ft2allowing a flow rate of
600 gal/d. Models H2 and H3 have a longer retention time capacity to adapt to local regulations.
Also, there are two different types of assembly of the systems. The letter Astands for a completely assembled
system shipped to the customer for installation with crushed stone and filtering media already inside the
Ecoflo® Peat filter, leaving only the distribution components installation and the in-ground installation. The
letters NA stand for a system shipped without the crushed stone and the filtering media inside the Ecoflo®
Peat filter. These components are set in place on site.
The quantity of Ecoflo®Peat filters per system is indicated by the numbers 1,2,3.

Guidelines for Use
The Ecoflo®Peat Filter is a biofiltration system designed to treat domestic wastewater from a residential house. It is installed
downstream of the septic tank equipped with an effluent filter and a flow regulator. It can also be used to treat wastewater from
commercial, communal and municipal projects. Please refer to the Commercial Design Guide for more information.
To ensure optimum treatment efficiency and operation of any septic installation (Ecoflo®Peat filter,
leach field, etc.), you should always:
Avoid discharging any of the following substances into the sewer:
•water softener backwash
•oil and grease (engine oil, cooking oil, etc.)
•wax and resins
•paint and solvents
•petroleum products
•pesticides of any kind
•any kind of septic tank additive
•toxic substances
•anything not easily biodegradable (e.g. coffee beans, cigarette butts, sanitary napkins, tampons, condoms).
Avoid:
•using an automatic toilet bowl cleaner
•using a garbage disposal or sewage pump (upstream of the septic tank)
•
And never:
•cover or bury the access lids of the Ecoflo®Peat filter system
•plant trees within 10' of the Ecoflo®Peat filter
•open or enter the Ecoflo®Peat filter system without prior authorization
•connect a drainage pipe, roof gutter or sump pump to the septic system.
Note:
There is no special action required if the system is to be used intermittently or if extended periods of non-use are anticipated
What You Should Know
Keep heavy weights off your septic installation
Never drive vehicles or place objects weighing over 500 lbs within 6' of the lid. If you are planning to do some landscaping or
any other type of work, make sure you advise those involved so they do not damage your septic system.
Do not shovel or blow snow so that it accumulates on top of the septic system. The overload could cause damage.
Mark/indicate the location of system components.
Concerning your home
Your home must be equipped with a working air vent, and plumbing must conform to the local building Code. Any change in
the use or function of your home, or any modification to your Ecoflo®Peat filter system must be authorized by the local
authorities, and Premier Tech Environment must be informed. The warranty for the Ecoflo®Peat filter system will be void
if this condition has not been fully respected.

Maintenance
Ecoflo®Peat Filter
The owner of a biofiltration system shall follow the manufacturer’s recommendations respecting maintenance of the
system. For that purpose, he must at all times have a valid contract with the manufacturer or its representative, and a copy of
the contract must be filed with the local authorities where the system is located.
Because maintenance is essential to the proper functioning of the Ecoflo®Peat Filter, it comes with a maintenance
agreement binding Premier Tech Environment to service the Ecoflo®Peat Filter, free of charge for a limited period of time
following its installation (please see maintenance agreement for more details). Every Ecoflo®Peat filter system sold has to be
serviced annually for the duration of its useful life.
Bi-annual maintenance for the first two (2) years and annual maintenance for
the following six (6) years (5 annual services) are carried out by Premier Tech
Environment or an authorized agent. This service includes a visual inspection
of all components to ensure the system is functioning properly and an effluent
quality inspection consisting of a visual assessment for color turbidity and an
olfactory assessment for odor. It also includes the raking of the filtering media
on an annual basis and the cleaning of the tipping bucket failure sensing device.
You will be given a maintenance record after each inspection, which you shall
keep with this manual in a safe place. If a problem is observed during the
inspection that cannot be remedied at the time of the inspection, the maintenance record will include an estimated date of
correction.
The filtering media should normally be replaced every eight (8) years at the most, depending on use and compliance with
the above guidelines. The filtering media is easily pumped out with a regular sewage disposal truck. The replacement media
must be installed by an authorized agent. Easy access to the lids is essential for maintenance purposes. If the peat filter is still
in good conditions, it is possible to extend the initial maintenance agreement on a case by case basis.
Septic tank
Emptying your septic tank as instructed helps keeping your septic system in proper working order. We recommend that you
keep proof of pumping (invoice) with this owner’s manual so as to keep a record of complete system maintenance. The
pumping standards of the septic tank prescribed by local authorities must be respected. For main residences, the septic tank
should be inspected yearly. It should be pumped out (first and second compartments) at least every 2 years or when a
maximum depth of sludge of 20 inches is reached in the first compartment, whichever comes first. However, when a by-law
governing the pumping of septic tanks has been adopted by a municipality or county, a septic tank may need to be pumped out
after measuring the scum or sludge layer. Consult your local regulations for prescribed inspection and pumping frequency.
PTE's effluent filter EFT-080R (H/H2)
We recommend an inspection of the filter once a year. Cleaning of the effluent filter should be
done each time the septic tank is pumped. However, the frequency of maintenance will depend on
wastewater flow, regulation requirement and the type of establishment. Pull the cartridge out of its
container and gently hose it off to remove any scum. You must do this while holding the filter over
the septic tank first compartment so that scum washes back into the tank.
Visual and audio alarm Unit
The Ecoflo®Peat filter system is equipped with a high-water level alarm float fixed to the effluent filter
and another one is included in the Ecoflo®Peat filter. A third alarm float is located in the pumping station
of the STB-650BR series only. All floats are connected to an alarm panel. This panel must be installed
inside the residence so the alarm can be heard as soon as it comes on. The operation of this unit is
described below.
If water reaches an unusually high level, the visual and audio alarm comes on. To turn it off, push the
“SILENCE” button. It is important to note that this will not solve the problem. If this situation happens,
call a service representative right away. You can test the alarm system to make sure it is operating properly
by pushing the “TEST” button; the visual and audio signals should come on.

Version 6.1: 2007-02-01
What to do in case of...
Flooding
Certain sites are prone to flooding or phreatic rise, which can cause malfunctioning of the Peat Filter or any other septic
system. If this happens, contact Premier Tech Environment.
Backflow
Backflow rarely occurs in homes. It is generally caused by the septic tank. If it happens, the visual and audio alarms will come
on. Your septic system installer or septic tank pumper can usually tell you what to do.
Odors
The positioning of the air vent, as well as other factors unrelated to the Peat Filter, can prevent proper dispersion of septic
gases and lead to odors. If this happens, contact Premier Tech Environment for solutions.
To obtain information such as serial number, system capacity, system classification or service, you should refer to the system
data plate located on the alarm panel or inside the main access. To access the system data plate in the Ecoflo®Peat Filter main
access, you have to unscrew the lag screws located at the corner of the lid. Do not remove the blue insulating board located
inside the main access which sealed the Peat Filter with Premier Tech ty-raps.
For any problem, broken or missing part,
contact our customer service at 1-800 632-6356
