The characteristics of continuous operation are as follows:
Snapshot 1: steady state; after an initial startup period, there is no variation of concentrations with time
Snapshot 2: constant reaction rates, where

is the biomass reaction rate,

is the reaction rate of the consumed reactant and

is the product reaction rate
Snapshot 3: Washout of the organisms (cells) will occur when the dilution rate

is greater than the specific growth rate

. This corresponds to the complete removal of cells by flow out of the tank. In many references, including [1], the variables

,

,

and productivity

are plotted versus the dilution rate

, which characterizes the steady state in a chemostat. See Related Links.
Some suggestions for the user:
Increase

interactively to note effect on washout.
Change the feed substrate concentration

to alter the steady state.
Investigate the influence of maintenance requirements on the steady-state biomass concentration.
Operate initially as a batch reactor with

, and switch to chemostat operation with

.

is the maximum specific growth rate, and in this case was set up to

.
Calculate

, the biomass-substrate yield, making use of the yield graph.
