6.4 Take sample of activated sludge from reactor chamber
•
measure current water level in reactor ( HR )
•
aerate reactor per manual mode for 2min
•
evaluate mixing and size of bubbles
•
take 250 ml sample of mixed activated slugde and fill into 1000 ml cylinder
•
fill up with 750 ml of clearwater from sample pot (using the small sample
taking device) to reach “1+3 dilution”
•
allow settlement for 30min
•
multiply resulting sludge level by factor 4 to get SSV30 in ml/l
•
take picture and save it as part of maintenance report
•
Measure sludge volume in all chambers/tanks.
•
Contrary to regular SBR-plants the Solido SMART system is working with
comparatively high sludge volume values.
Why dilute 1+3?
Example after 30min
sedimentation:
The result of
600ml/l is
much closer to the real
conditions in the tank.
Undiluted
SSV30=
930ml/l
Dilution „1+3“:
SSV30= 150ml/l x 4 =
600 ml/l
