The process in which a tank or reactor is filled, water is treated, then the tank is emptied, and the cycle repeats is called which?

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

Answer: (A)

This is a batch process. In a batch setup, you charge the tank with a fixed amount of water, treat that specific quantity through the process, and then discharge it before starting the next charge. The cycle—fill, treat, empty, then repeat—shows discrete, separate lots being processed rather than a continuous flow through the system. If it were continuous, water would be constantly moving in and out at steady rates, keeping the tank in a near-constant state without a complete emptying between cycles. A semi-batch would involve adding material during the process or removing part of the content while still feeding, rather than fully emptying the tank after each treatment. So the described operation aligns with a batch process, reflecting discrete treatment cycles.
