ASM Aerobic Digestion Add-on (ASM_AeDigAddOn)

class qsdsan.process_models.ASM_AeDigAddOn(ID, k_dig=0.04, components=None)

Creates a Process object representing the degradation of particulate inert organic materials that typically occur in an aerobic digester. Stoichiometry is determined by rules of element conservation in corresponding activated sludge models.

Parameters:

k_dig (float, optional) – The 1st-order degradation rate constant, in d^(-1). The default is 0.04.
