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.

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.

Vacation, 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.
