The Eco-Pure Waste Water Systems 300 Series Peat Moss Biofilter is an advanced
secondary wastewater treatment system that utilizes a specially cultivated and harvested
sphagnum peat moss for the treatment of septic tank effluent. Sphagnum peat moss
provides an excellent environment for micro and macro organisms that provide a high
level of wastewater treatment. The treatment occurs by a combination of physical,
biological and chemical processes. Due to it’s unique process, the 300 Series Peat
Moss Biofilter is patented.

The raw wastewater first enters a septic tank where pre-treatment of the wastewater
occurs. Please note that a septic tank effluent filter is required for every Eco-Pure
system. From the septic tank, the effluent enters the Eco-Pure 300 Series Peat Moss
Biofilter either by gravity or through the use of pump tank containing a small incremental
horsepower effluent dosing pump, typically 1/3 to 1/4 HP.

The above parameters are considered the Advanced Secondary Treatment Standard for
wastewater.

The wastewater first enters a septic tank where pretreatment of the wastewater occurs.
Please note that a septic tank effluent filter is required for every Eco-Pure system. After
the septic tank the effluent enters the Eco-Pure 300 Series Peat Moss Filter either by
gravity or through the use a small horsepower effluent pump. The wastewater enters the
300 Series Peat Moss Filter at the top of the module and is evenly distributed over the
peat bed through a distribution plate. The effluent flows downward through the peat and
the highly treated effluent is discharged at the bottom of the module.

Overview
Eco-Pure Peat Moss Biofilter System Overview

Each module is capable of treating peak flows of up to 600 gallons of wastewater per
day from a four bedroom home up to 3,200 square feet in size (homes larger than this,
with 5-8 bedrooms, require a second peat unit). This is based on typical, residential
strength wastewater. Properly installed, operated and maintained, test results have
shown the effluent discharged from the 300 Series Peat Moss Biofilter to meet the
following standards:

•        < 20 mg/l Biochemical Oxygen Demand (BOD5)
•        < 20 mg/l Total Suspended Solids
•        99.99% Fecal Coliform Bacteria Removal

The wastewater enters the 300 Series Peat Moss Biofilter at the top of the module and
is evenly distributed over the sphagnum peat moss bed through a high density
polyethylene distribution plate, placed directly on top of the peat moss. The retention
time of the septic tank effluent within the sphagnum peat moss is critical to the
performance of the 300 Series Peat Moss Biofilter. This allows time for each organism
within the peat moss to do it’s role in treating the septic tank effluent and allows for
proper filtration of the wastewater. Depending on daily flows, detention time can range
from 8 to 24 hours.
A predetermined amount of sphagnum peat moss is placed within the proprietary high-
density polyethylene (HDPE) module. This amount was determined through the
extensive research and development of the system.
The amount of peat moss used is controlled by the use of pre-packaged peat “pillows”.
The pillows are mesh, polypropylene, non-degradable bags filled with sphagnum peat
moss. The pillows are filled to the appropriate amount using an automated machine at
Eco-Pure’s facility.
Each module contains 42 pillows. Properly placed, the pillows will fit together without
any void space. The pillows are placed in two rows, perpendicular to each other, one on
top of the other. In order to fill in any potential voids, the placement of ten (10) loose peat
moss bails is required. The peat moss pillows and bails are placed on a pallet and
shrink wrapped. One module contains one pallet of peat.

The treated effluent is collected at the bottom of the module in a 4” diameter collection
pipe. This 4” pipe sits in the channels manufactured in each module. The treated effluent
is discharged at the bottom of the module.
The 4” pipe also serves as a vent pipe for the 300 Series Peat Moss Biofilter and is
critical to the performance of the system. The vent pipe runs to the top of the module
and is connected to the vents located on each side of the cover. This cover cannot be
buried to allow for air movement throughout the peat moss. Many of the organisms
responsible for treating the wastewater cannot live in an anaerobic (without air) thus
blocking the air vent is detrimental to the system.
The dimensions of the high density
polyethylene (HDPE) module are 7 feet
wide x 10 feet long x 4 feet high. Eco-Pure,
Inc. manufactures the module at it’s Fort
Myers, Florida facility, using the rotational
molding process. Eco-Pure uses only
virgin HDPE resin for the module. This
assures uniformity and structural integrity
of the module. In addition, the resin
contains the highest form of protection
against harmful ultra-violet (UV) light.
