Chemical
cleaning
routine
for
the
AQUALOOP
system:
A
cleaning
option
is
available
on
the
control
menu
of
the
AQUALOOP
controller
.
A
semi
‐
automatic
cleaning
of
membrane
cartridges
can
be
performed
without
the
need
to
dismount
the
membranes.
Menu
steps
for
cleaning
routine:
Proceed
to
menu
11
1.)
Confirmation
for
starting
the
cleaning
routine
2.)
Controller
automatically
starts
the
sludge
pump
until
the
minimum
level
of
water
is
reached
in
the
bioreactor
(BRmin).
Note:
If
no
internal
sludge
pump
is
connected,
then
the
bioreactor
should
be
pumped
out
with
an
external
(submersible)
pump
until
"BRmin
‐
"
appears
in
the
display
(with
a
simultaneous
sound
of
5
beep
tones)
Attention:
The
suction
pump
(lower
pump)
must
not
be
allowed
to
run
dry!
Also,
lowering
the
water
level
below
will
mean
that
the
system
will
not
re
‐
start
until
the
bioreactor
level
fills
up.
3.)
When
the
controller
shows
"BRmin
‐
",
then
a
backwash
process
is
automatically
performed
to
empty
the
backwash
tank.
This
procedure
ends
automatically
or
can
also
be
terminated
manually.
4.)
Now
the
cleaning
solution
(s.
section
11.6.3)
can
be
added
through
the
cleaning
connection.
In
small
tank
systems
with
good
accessibility
(e.g.
AL
‐
GW200)
the
cleaning
solution
can
be
filled
directly
into
the
backwash
tank.
Note:
The
cleaning
solution
must
be
refilled
during
the
cleaning
process
in
the
case
more
than
three
membranes
are
installed,
as
the
backwash
tank
has
only
6
L
of
capacity
and
each
membrane
requires
2
L
of
cleaning
solution.
5.)
When
the
cleaning
solution
is
filled,
then
the
cleaning
cycle
starts
with
ENTER.
A
pre
‐
set
cleaning
routine
now
runs.
The
routine
takes
about
one
hour.
6.)
After
the
completion
of
the
cleaning
routine
a
clear
water
flush
must
be
started.
At
least
two
litres
of
clear
water
must
be
filled
into
the
backwash
tank
for
each
membrane.
7.)
Press
ENTER
to
confirm
the
clear
water
flush.
The
routine
takes
max.
4
minutes.
Water
that
comes
out
of
the
pipe
must
be
disposed
of.
