Activated Sludge Process in a Batch Reactor
Contributed by:
R. Ricardo Sánchez
THINGS TO TRY
Slider Zoom
Gamepad Controls
Automatic Animation
SNAPSHOTS
DETAILS
The total suspended solids concentration is given by:
.
The rate of the attachment step is taken as:
.
The uptake substrate into the biomass follows Monod kinetics:
.
Cell death is assumed to follow first-order kinetics:
.
Notation:
: mass transfer coefficient
: storable substrate fraction (dimensionless)
: saturation constant
: specific death rate
The model is described in detail in [1, Example 3.3.1. Model of a Batch Activated Sludge Process].
