Which treatment process is defined as filling a tank, treating the water, and then emptying the tank?

• A. Batch process
• B. Continuous process
• C. Recirculation process
• D. Ion exchange

Answer: (A)

In batch processing, you load a defined amount of water into a tank, treat it, and then discharge it before starting the next batch. This exact sequence—fill, treat, then empty—fits the description given. It allows you to control treatment time and dosing for each discrete charge. Continuous processing, by contrast, keeps water moving through the system in a steady flow, without emptying a tank between loads. Recirculation involves looping water back through a unit to increase contact time, not a single fill-and-empty cycle. Ion exchange is a treatment method using resin to swap ions; while it happens in tanks or beds, it isn’t defined by the fill-treat-empty batch pattern.
