Chemical cleaning routine for the
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 pump until "BRmin -"
appears in the display (with a simultaneous 5 beep tones)
Attention:
The filtration pump (lower pump) must not be allowed
to run dry!
3.)
When the controller shows "BRmin -", 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.
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.
