The
ALSI
Consolidation
Dewatering
System
offers
cost
effective
continuous
paint
sludge
collection,
consolidation,
dewatering
and
removal.
ALSI
equipment
designs
are
compatible
with
all
suspension/flotation
chemical
programs.
ALSI
design
objectives
are
to
optimize
scrubber
efficiency,
reduce
disposal
costs,
and
minimize
booth
downtime
for
cleaning.
ALSI
systems
have
been
online
since
the
early
1980’s.
Our
track
record
includes
hundreds
of
installations
of
all
sizes
and
complexities.
From
central
systems
to
satellite
booths,
ALSI’s
high
performance
sludge
processing
systems
are
suitable
for
any
type
of
wet
booth
design,
single
or
multiple.

three
chamber,
CheckMark
design
optimizes
a
wide
operating
range
of
chemical
treatment
programs
to
produce
dry
paint
sludge.
Liquid
Extraction
Chamber’s
(LEC)
deep
pool
provides
substantial
buffer
for
variable
sludge
feed
rates
and
adequate
residence
time
for
solids
coagulation
and
the
wicking
away
of
free
water.
Dry
Down
Chamber’s
(DDC)
enhances
water
removal
utilizing
warm
air
flow
down
and
across
the
sludge
cake
producing
dewatering
efficiencies
as
high
as
50%
by
weight.
Media
Release
Chamber
(MRC)
aerates
the
filter
media
from
below,
drying
the
sludge
and
allowing
release
and
separate
disposal
of
sludge
and
media.
Dewatering

Filter
Operatio
n
Wet
paint
sludge
enters
the
LEC
(1)
and
begins
to
form
a
cake
(2)
on
top
of
the
filter
media
(3)
that
is
supported
by
the
permanent
flat
wire
belt
(4).
As
the
sludge
cake
builds
to
optimum
depth
and
density,
the
Level
Detector
(5)
initiates
the
automatic
media
index
cycle.
The
media
drive
motor
(6)
is
energized,
and
as
fresh
media
takes
its
place,
the
spent
media
with
drying
sludge
cake
rides
up
the
sloped
Drying
Ramp
(7)
into
the
DDC.
The
adjustable
Doctor
Blade
(8)
sets
the
depth
and
density
of
the
sludge
cake
assuring
even
drying
airflow.

Two

combine
to
dry
the
sludge
cake.
The
V2
Vacuum

in
the

The
V1
Vacuum
Producer’s
(10)
high
volume,
low

warm

accelerates
dry

as
the
paint
sludge
moves
through
the
DDC.

The
combined
warm
air
output
(11)
from
both
Vacuum
Producers
flows
over
and
through
the
sludge
cake
to
maximize
sludge
dry
down
efficiency.
A
split
stream
of
the
Vacuum
Producers’
warm
exhaust
is
directed
under
(12)
the
sludge
cake
in
the
MRC
to
provide
additional
drying
and
then
separate
the
cake
for
release
from
the
media.
