How does
Acoustic
Advanced
Oxidation
do what
it does?
-
It
makes
available
greater
porosity
(especially
micro-pores)
in
the
sand
system
so
pollutants
are
adsorbed
instead
of
released
-
It
oxidizes
adsorbed
VOCs
-
It
alters
the
surface
charge
of
the
clay
-
It
provides
better
hydration
of
the
clay
Beneficial
Results
of
Acoustic
Advanced
Oxidation
-
Reduced
organic
pollutants
-
Higher
strength
per
unit
of
clay
binder
-
Less
clay
and
coal
needed
to
produce
quality
castings
Summary
of
ongoing
clay and
coal
pore
structure
government
funded
research
-
The
pore
structure
of
foundry
sand
changes
-
The
increase
in
porosity
allows
the
entire
green
sand
system
to
act
in a
similar
way
to
an
activated
carbon
adsorption
bed
-
Acoustic
AO
changes
the
pore
structure
of
foundry
clay
recycled
from
air
pollution
control
systems
more
than
standard
AO
methods
-
The
pore
structure
is
not
available
in
non-AO
systems:
fewer
pores
are
created
and/or
pores
are
clogged/filled
-
Continuing
research
allows
us
to
improve
the
process

SONOPEROXONE®
INSTALLATIONS
-
The
first
system
was
developed
to
reduce
condensable
organic
particulate,
odor
and
smoke
in
1994
-
The
second
was
installed
to
reduce
scrap
rate
caused
by a
wet
collector’s
oily
residue
in
the
conventional
blackwater
system
-
The
third
was
installed
to
reduce
Organic
HAPs
and
to
study
clay
recycle
methods
-
All
systems
have
reduced
neighborhood
odor
complaints
and
associated
legal
costs
-
Most
are
now
installed
to
reduce
clay/coal
consumption
and
solid
waste
costs
-
Most
achieve
scrap
rate
reductions
after
the
systems
are
fully
implemented
and
sand
properties
are
re-optimized
