Which type of chlorine gas feeder is most commonly used in water treatment?

• A. Gravity-fed system
• B. Vacuum system
• C. Diffusion system
• D. Pressure-fed system

Answer: (B)

The most commonly used type of chlorine gas feeder in water treatment is the vacuum system. This system operates by creating a vacuum that draws chlorine gas from a pressurized cylinder into a water solution, ensuring accurate dosing and control over the amount of chlorine introduced into the water. The vacuum mechanism is crucial as it minimizes the risk of gas leaks, providing both safety for the operators and consistent treatment performance. In practice, vacuum systems allow for reliable handling of chlorine gas, which is essential for disinfection processes in water treatment facilities. The ability to precisely regulate the chlorine concentration ensures that water is treated effectively, meeting public health standards. Other types of feeders may not offer the same level of safety and efficiency. Gravity-fed systems, for instance, rely on the weight of the chlorine or water to push gas into the system, which can be less controlled and may lead to inconsistent dosing. Diffusion systems, while effective in certain applications, are typically not as common in standard water treatment settings. Pressure-fed systems can introduce complexities associated with managing high pressures and potential release of gas, making vacuum systems a preferred choice for their simplicity and safety.
