GENERAL

:
Petroleum

Wastewater
Issues
TOPICS
DISCUSSED
AND
ACTION
TAKEN
Mr.
Pickering
called
me
in
response
to
an
e­
mail
contact
with
U.
S.
Filter.
I
asked
him
about
the
use
of
activated
carbon
to
control
releases
of
toxic
organic
compounds
from
petroleum
refineries.
Mr.
Pickering
said
he
was
familiar
with
a
number
of
facilities
that
add
powdered
activated
carbon
(
PAC)
to
their
biological
treatment
system
so
that
their
effluent
can
"
pass"
toxicity
tests.
They
add
sufficient
carbon
to
pass
the
test.
The
PAC
can
be
added
on
a
"
once­
through'
basis,
meaning
that
it
is
discarded
with
waste
biological
sludges.
In
some
cases,
the
refinery
uses
on­
site
wet
air
oxidation
to
regenerate
the
carbon
and
reuse
it.
Whether
on­
site
regeneration
is
economical
depends
on
the
size
of
the
facility
and
amount
of
carbon
used.

For
further
information
about
U.
S.
Filter's
fluidized
GAC
system
and
wastewater
treatment
in
the
petroleum
refining
industry,
Mr.
Pickering
suggested
that
I
contact
Tom
Schultz,
U.
S.
Filter's
market
manager
for
the
petrochemical
industry.
Mr.
Schultz
is
in
the
Envirex,
Waukesha,
WI
