Summary
The
Situation
A major
rendering
facility
was
experiencing
problems
with
its
Wastewater
Treatment
Plant
because
of high
influent
loading
during
the
summer
season.
Odor
from
the
plant
was
headlined
in news
articles
and
foaming
attributed
to filamentous
bacteria,
which
plugged
pumps
and
decreased
the
plant's
efficiency.
The
Solution
Bio-Form LLC
proposed
a bioaugmentation
program
that
consisted
of the
addition
of BZT®
Waste
Digester
to the
system.
It was
proposed
that
an initial
seed
application
be performed
followed
by regular
weekly
maintenance
applications.
The
treatment
program
was
designed
to:
- Reduce
solids
- Enhance
Stability
- Reduce/eliminate
odor
- Breakdown
H2S
- Reduce
the
total
overall
sludge
volume
- Increase
plant
capacity
and
efficiency
- Increase
plant
ability
to
handle
upsets
and
shocks
The
Results
Within
one
month,
solids
were
reduced
by up
to 20%.
The
odors
had
all
but
disappeared.
The
foaming
and
filamentous
problems
were
greatly
reduced
after
two
months,
and
eliminated
after
three
months.
The
program
provided
positive
payback
within
three
months,
attributed
to:
- Reduction
in
hauling
costs
- Reduction
in
polymer
usage
- Elimination
of
chlorine
The
program
has
demonstrated
the
broad
ranging
effects
of BZT®
Waste
Digester
and
its
ability
to reduce
the
odor
in the
surrounding
community
and
save
thousands
of dollars.
