Immediate cause for ARGUS Immediate cause for ARGUS applicationapplication

WWTP OLAZ performance: Sludge volume index >250-300ml/g, washout of MLSS Nitrogen removal, external C-source COD recalcitrants

Secondary benefits: Sensitivity to toxically composition of leachate water reduced Sludge production reduction, sludge costs

Towards full-scale project:  lab research & selection go-no go selected aerobic granular

biomass cultivated and scaled up in propagators P1 and P2,

cultivated granular biomass transfered from P2 to the full-scale plant

full-scale plant scaling up via west street – P3

WWTP OLAZ: Laboratory tests

Go No Go Lab research Acceleration of ammonium oxidation; (between 1,4 -2

faster); Lowering methanol dosage (goal: reduction 30 - 50%); Improvement of sludge sedimentation: SVI <150 ml/g; Lowering sludge production (d.d.15-05-03 from ca. 97 kg

MLSS - per day; reduction 30 - 50%). Improvement of COD removal between 20 en 50 %

(depends on recalcitrant fraction), Total improvement ca. 20-50%; Increased tolerance on inhibitory effects of toxic substances. Energy reduction (less O2 for COD oxidation).
