Endogenous Decay Coefficient in Design of a Complete Mix Activated Sludge Reactor Formulas

Endogenous Decay Coefficient refers to the rate at which microorganisms in the biomass consume their own cell mass in the absence of an external food source. And is denoted by k_d. Endogenous Decay Coefficient is usually measured using the 1 Per Day for First Order Reaction Rate Constant. Note that the value of Endogenous Decay Coefficient is always positive. Typically, the value of Endogenous Decay Coefficient lies in the range from 0.025 to 0.075.

FAQ

What is the Endogenous Decay Coefficient?

Endogenous Decay Coefficient refers to the rate at which microorganisms in the biomass consume their own cell mass in the absence of an external food source. Endogenous Decay Coefficient is usually measured using the 1 Per Day for First Order Reaction Rate Constant. Note that the value of Endogenous Decay Coefficient is always positive. Typically, the value of Endogenous Decay Coefficient lies in the range from 0.025 to 0.075.

Can the Endogenous Decay Coefficient be negative?

No, the Endogenous Decay Coefficient, measured in First Order Reaction Rate Constant cannot be negative.

What unit is used to measure Endogenous Decay Coefficient?

Endogenous Decay Coefficient is usually measured using the 1 Per Day[d⁻¹] for First Order Reaction Rate Constant. 1 Per Second[d⁻¹], 1 Per Millisecond[d⁻¹], 1 Per Hour[d⁻¹] are the few other units in which Endogenous Decay Coefficient can be measured.
