Premier Tech 27 / 64 Solido SMART
DOKK5110E 15.04.2020
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.
