Consider a falling film evaporator that processes whey permeate. A totally clean evaporator may be able to process 40,000 L/hr of whey permeate. By the end of a run, perhaps only 32,000 L/hr can be processed and give the same product. This has two effects. Firstly, at the end of the run the reduced flow rate must still be spread over the same area.
