WebNov 26, 2014 · Continuously Stirred Tank Reactor (CSTR) A reactor is used to convert a hazardous chemical A to an acceptable chemical B in waste stream before entering a nearby lake.

WebA unique feature of a biological CSTR is the washout point. When the flow rate is increased so that the microbes can no longer reproduce fast enough to maintain a population, the microbes wash out of the tank, and the reaction ceases. This washout point represents the limits of maximum flow rate for operation. IV.D.2 Classification WebA CSTR is a simple and inexpensive design for an ...
