&
Sludge
Reduction
A rendering
facility
had
numerous
wastewater
lagoons
where
they
faced
a number
of issues.
- Heavy
sludge
build
up
- Oil & Grease
caps
had
begun
to
take
over
the
lagoons
- Local
businesses & residents
complained
of
odors
-
Regulatory
limits
were
in
jeopardy
-
Possible
need
to
dredge
the
lagoons
and
dispose
of
the
sludge
United-Tech
personnel
proposed
a bioaugmentation
program
that
consisted
of the
addition
of BZT®
Waste
Digester
throughout
the
lagoon
system.
United-Tech
proposed
that
an initial
seed
application
be performed
followed
by regular
weekly
maintenance
applications.
The
program
was
designed
to decrease
overall
sludge
volume,
decrease
oils
&
greases,
and
keep
odors
under
control.
THE
RESULTS:
Within
days
of the
initial
seed
application,
there
was
an impressive
decrease
in the
odor
generated
from
the
lagoons
and
the
oil
and
grease
cap
had
been
taken
under
control.
Eventually,
the
odors
from
the
lagoons
were
ELIMINATED.
Sludge
depth
readings
were
taken
at 60
days
and
120
days.
The
initial
readings
at 60
days,
showed
an average
sludge
reduction
of 45%
across
all
the
lagoons.
The
sludge
depth
readings
taken
at 120
days
showed
all
but
3-6
inches
[7.62cm-15.24cm]
of sludge
left
in two
of the
lagoons,
with
sludge
reductions
of over
60%
in two
other
lagoons.
The
company
continues
to rely
on BZT®
Waste
Digester
for
its
performance
and
benefits.
The
corporate
headquarters
of the
subject
company
is now
introducing
BZT®
Waste
Digester
and
United-Tech
to many
of its
other
facilities
nationwide.
