How does cleaning work and how long does it take before it can be reinoculated?

The reactor is equipped with rotary spray balls and a spray pump to wash the tank internally between culture runs. Cleaning and sterilizing between culture runs in a 2 step process: biofilm removal and chlorine sterilization. Downtime is very minimal and cleaning hardly takes any effort. Though the cleaning cycle takes 2-4 hours, you can be doing more productive things during that time, than cleaning the tank while you let the spray system work for you.
