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.
