11.6.2.3 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 (s. Chapter 13 -Optional accessories-) (If the membrane station is covered in sludge it must first
be cleaned manually (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 , 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. See figure below:
