After
completion
of
the
clear
water
flushing,
the
operation
mode
appears
in
the
display
and
the
normal
program
continues
to
operate
further,
corresponding
to
the
set
parameters.
In
case
a
chlorine
cleaning
routine
is
required
after
the
acid
cleaning
the
cleaning
menu
routine
must
be
started
again.
ATTENTION!
If
chlorine
cleaning
is
performed
after
acid
cleaning,
then
the
pipes
must
be
sufficiently
rinsed
(s.

1.6.2.2
Intensive
cleaning
in
separate
cleaning
tank
Description:
The
AQUALOOP
membrane
station
is
taken
completely
out
of
the
bioreactor
and
put
in
a
separate
cleaning
container.
(If
the
membrane
station
is
covered
in
sludge
it
must
first
be
cleaned
(s.
section
11.6.1).
The
cleaning
container
is
filled
with
the
cleaning
solution
(40
L
for
AL
‐
CTank60L
and
160
L
for
AL
‐
CTank350L)
and
water
up
to
the
top
of
the
pump
unit
(700
mm).
Please
see
the
cleaning
concentration
described
(s.
section
11.6.3)!
The
pump
unit
is
connected
with
the
control
unit
in
the
standard
manner.
The
goal
is
to
circulate
the
cleaning
solution
under
normal
pressure
and
flow
rate
for
24
hours.
Therefore,
the
start
times
T1
and
T2
and
filtration
cycles
have
to
be
set
as
follows:
Start
times:
T1
/
T2
=
16:00
/
04:00
Suction
cycles:
A1
/
A2
=
30
/
30
After
the
cleaning
process
the
cleaning
solution
is
disposed
of
and
clear
water
is
filled
into
the
cleaning
container
to
the
top
of
the
pump
unit
(700
mm).
After
flushing
with
clear
water
for
one
hour
the
used
clear
water
is
disposed
of.
A
second
cleaning
with
clear
water
is
made
in
the
same
way,
after
which
the
cleaning
process
is
finished.
The
membrane
station
is
then
put
back
into
the
bioreactor
and
connected
to
the
original
control
unit.
Example:
Cleaning
AQUALOOP
membrane
station
,
single
(one
membrane):
The
cleaning
tank
is
placed
near
the
system
to
connect
the
pumps
with
the
existing
control
unit.
Be
sure
the
room
in
which
the
cleaning
takes
place
is
well
ventilated!
Note:
The
bottom
aeration
distributor
should
be
swapped
with
the
flat
stand
(part
of
the
AL
‐
CTank60L)
to
close
the
tank
cover
during
cleaning.
