I am trying to implement in my model a condition that could let me to automate an specific bypass of a % of the influent flow to the primary decanter depending on the value of the DQO/NTK relationship. For example, two orders that I want to create are that when DQO\NTK= 6, then the 0% of the influent flow bypasses the primary decanter, but when DQO\NTK= 8, then the 25% of the influent flow bypasses the primary decanter.
As a first step, I am able to create the new variable "DQO\NTK in the influent" with the calculator tool, but I am not sure about what other blocks I should use in order to create this kind of automation that I would like to implement. I do not see a direct application to this aim with the typical blocks of control like "timers" and "PI", etc....
Thanks for your help and time.
