A.
Inlet
Wastewater
enters
the
tank
or
basin.
By
gravity,
liquid
passes
through
the
cloth
membrane.
Solids
collect
on
the
outer
surface
of
the
media,
forming
a
mat.
The
filtered
liquid
then
enters
the
internal
portion
of
the
disk
where
it
is
directed
to
final
discharge.
B.
During
backwash,
disks
are
cleaned
in
multiples
of
two,
unless
a
single
disk
unit
is
utilized.
Disks
rotate
slowly,
allowing
each
segment
to
be
cleaned.
Backwash
water
is
directed
to
the
headworks.
Filteration
is
not
interrupted
during
this
cycle.
C.
The
AquaDisk
filteration
process
requires
no
moving
parts
during
normal
filtration
and
influent
wastewater
remains
in
a
quiescent
environment.
Some
heavier
solids
may
settle
to
the
bottom
portion
of
the
filter
tank.
These
solids
are
then
pumped
on
an
intermittent
basis
back
to
the
headworks,
digester
or
other
solids
collection
area
of
the
treatment
plant.
D.
An
automatic,
intensive
cleaning
process
can
be
initiated
as
needed
to
thoroughly
clean
and
prevent
biogrowth
on
the
cloth
media.
This
cleaning
process,
without
the
use
of
chlorination,
is
achieved
by
a
high-pressure
spray
which
is
an
integral
feature
of
the
AquaDisk.
Both
the
intensive
cleaning
process
and
the
automatic
backwash
process
are
controlled
by
a
simple
PLC.
