A process in which a tank is filled, the water treated, then the tank is emptied, and the process repeated is called ______.

• A. Batch process
• B. Continuous flow
• C. Semi-batch
• D. Recirculation process

Answer: (A)

This is about a batch operation. In a batch process the tank is filled, the water is treated, and then the tank is emptied before starting the next cycle. Each cycle is a complete, self-contained unit, which allows you to control treatment conditions precisely for that batch and ensures no material carries over to the next cycle until the tank is restarted. Continuous flow would involve a steady, ongoing input and output with treatment happening as water moves through the system, not in separate fill-treat-empty cycles. A semi-batch blends elements of both, but the defining feature is not a pure fill-treat-empty cycle. Recirculation means part of the flow is returned to an earlier stage or looped back, rather than forming discrete treatment cycles in a single tank.
