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. step 6 above)
11.6.2.2 Automatic In-Situ cleaning in the bioreactor (multiple control unit)
Description:
The fully automatic cleaning requires the AL-ACLEAN accessory (optional) and is automatically controlled
by the central control unit.
The required daily treatment flow can be set via the setting in the multi controller menu. If the value falls
below this value on four consecutive days, automatic cleaning is activated.
A chemical cleaning with citric acid is carried out if local water hardness is >6°dH. For this purpose, the
cleaning solution is pressed into the membrane fibers at a defined time interval with 5 dosing cycles.
Cleaning, including rinsing the pipes (into the sewer), takes approx. 2 hours.
After a rest phase of 1 hour, the chemical dosing with chlorine takes place. This cleaning step also requires
2 hours with a rest phase of 1 hour.
After approx. 6 hours, the system returns to filtration mode.
