6.6 Desludging
•
Make sure of desludging (on demand) if SSV90
norm
-level (referred to HRmax) is
reaching 700 ml/l (measure with dilution 1+3 and multiply result by 4) .
•
For desludging make sure to use integrated desluding/inspection pipe (d=160mm)
indicated by this pictogramm only, in order to enable proper desludging and to
prevent damage to components.
•
Avoid desludging during sedimentation phase (around 12 to 2pm).
Recommended: between 2 and 3 pm, low water level after clearwater discharge.
•
There is no need to open the lid of the system or take out the capsule for desludging.
•
The design of the pipe will make sure that at least 10% of the volume will stay inside
the tank. This is mandatory to keep up the performance of the plant right after
desludging.
•
It is recommended to fill up tank with water after desludging (around 1/3 of max. level)
•
Make sure to document desludging in operations logbook
With SMART+P EM2 (two chamber tank M2) the desludging is done in the same way.
There is an opening in the baffle at a specific height, in order to desludge the first
chamber almost completely and leaving a water level of about 25cm in the second
chamber. Considering the whole volume there will remain enough sludge to continue
the biological process.
