What is the function of an eductor tube in a chlorine container?

The function of an eductor tube in a chlorine container primarily relates to the ability to facilitate the withdrawal of liquid chlorine. An eductor tube uses the principle of venturi flow, where a high-velocity liquid stream creates a low-pressure area that draws in a secondary liquid (in this case, the liquid chlorine) from the container.

This mechanism allows for effective transfer of chlorine when it is needed without requiring additional pumps, making it a vital part of chlorine delivery systems in wastewater treatment facilities. The ability to withdraw liquid chlorine efficiently is crucial because it ensures that operators can maintain appropriate chlorine levels for disinfection processes while also supporting safety measures to handle the chlorine gas as it converts to its gaseous state when needed.

The other options touch upon different processes but do not accurately describe the primary role of an eductor tube in chlorine handling. While regulating gas flow and enhancing diffusion are important aspects of gas management in disinfection practices, the specific function of the eductor tube centers around the withdrawal of the liquid chlorine for use in treatment processes.
