Summary
The
Situation
A food
company
that
manufactures
buttermilk
biscuits
on a
mass
scale,
faced
compliance
issues
with
the
local
pretreatment
program.
Oil
&
Grease
levels
in the
company's
wastewater
discharge
were
at levels
3-10
times
the
allowable
limits.
The
company's
wastewater
discharge
system
was
a series
of above
ground
tanks
that
transferred
wastewater
into
a large
grease
trap.
The
company
was
forced
to have
the
massive
grease
trap
pumped
twice
per
week.
The
Solution
Bio-Form LLC
recommended
a treatment
protocol
that
treated
each
above
ground
holding
tank
during
the
filling
stage.
A recommendation
was
also
made
to treat
the
grease
trap
directly.
The
Results
- The
company
has
gone
two
years
without
any
compliance
issues.
- The
grease
trap
only
requires
periodic
pumping,
saving
the
company
much
labor,
time
and
money.
- The
savings
associated
with
the
grease
trap
pumpings
have
paid
for
all
product
used
and
the
company
is
now
actually
saving
money.
